Multi-component wastewater from finely dispersed impurities treatment intensification

The article deals with the intensification of flocculation wastewater treatment from finely dispersed suspended dust particles that are formed in the foundry shop at machine-building productions. The dependence of the floc sedimentation rate and wastewater clarification on solid phase concentration and flocculant flow rate was experimentally researched using model wastewater created by mixing dust and water. The multicomponent impurities of ionic flocculants on the aggregation process impact were experimentally proven, and anionic and cationic flocculants combination high efficiency was shown. The optimal parameters for the wastewater treatment process were established. The best flocculating effect and minimum flocculant consumption were observed at a solid phase concentration of 8-14 g/l. It was established that the most effective aggregate formation process is observed when two flocculants’ types are used simultaneously: anionic A-19 and cationic K-7, not each type separately. Flocculant flow rate experimental and calculated dependences for the wastewater treatment process depending on solid phase concentration and floc sedimentation speed necessary for effective sedimentation have been established. A technological scheme for wastewater treatment from suspended dust impurities that are formed in foundry shop at machine-building enterprise has been developed. The scheme includes: wastewater flocculation; water clarification in a sedimentation tank; and water deironing by aeration with coagulant addition and further filtration. It is proposed to use purified water in enterprise technological cycle that helps to reduce tap water consumption.

A computational analysis on two phase Eyring-Powell (non-Newtonian) dust particles flow for heat and mass transfer phenomenon with variable thermal features

In this instigation, the heat and mass transfer pattern on Eyring-Powell nanofluid with suspension of dust particles is focused. For heat transfer phenomenon, the Eyring-Powell nanofluid capturing the variable thermal conductivity. Furthermore, the variable and mass diffusivity assumptions are entertained for summarizing the observations chemical reaction phenomenon. The flow is endorsed to magnetic force impact. The additional impact of Brownian motion and thermophoresis consequences have been adopted. The numerical computations with shooting technique are performed. The physical aspects of parameters have been observed graphically. Based on depicted observations, it is examined that the fluid velocity reduces due to interaction velocity parameter which reverse trend is noted for dust particles velocity. The temperature profile for dusty fluid particles enhanced due to interaction parameter for temperature. Furthermore, the concentration profile reduces due to concentration interaction parameter. Current results present applications in solar energy, thermal processes, heat transform devices cooling systems, plasma, manufacturing processes, energy systems, etc.

Measuring the concentrations of some gaseous air pollutants and dust particles in the western city of Hamzah in Iraq

This research concentrates on studying and analyzing the spatial and temporal variation of the concentrations of air pollutants in the Hamzah-western city during the four seasons of the year 2022 by studying the concentrations of gaseous pollutants in the air, such as NO2, SO2, CO, CO2, and O3, as well as measuring the concentrations of dust particles suspended in the air, such as PM2.5 and PM10. The number of sampling sites reached six, distributed into five different sectors (industrial, residential, transport, agricultural, and a mixed sector combining industry and transportation) in order to show the discrepancies in the concentrations of pollutants and explain their causes. The results of in situ measurements and laboratory analyses showed that there is a spatial and temporal variation in the concentrations of air pollutants. The highest concentrations of carbon monoxide CO, carbon dioxide CO2, and sulfur dioxide SO2 were recorded in sector 1 and during the summer season at concentrations of 38.5, 337, and 2.9 ppm, respectively. While the highest concentrations of nitrogen dioxide (NO2) were recorded in sector (2) with a concentration of 0.65 ppm, and all those concentrations were outside the permissible limits, the lowest concentrations were recorded for gases in sector (6), which covered all the study semesters. As for the concentrations of suspended dust particles in their sizes (PM2.5 and PM10), the highest concentrations were recorded in Sector (2), during all seasons of the study, and at 383.81 and 389.38 ppm concentrations, respectively. While the lowest concentrations of suspended particles of both sizes were recorded in Sector 6, a value of 119.65 ppm was recorded for PM2.5 minutes and 115.65 ppm for PM10 minutes. Thus, all their values during the study period were greater than the permissible limits.

Dusty non-Newtonian nanofluid flow along a stretching curved sheet via chemically reactive and heat source/sink imapct: Two-phase model

The momentousness of studying the similar solution of MHD flow along a curved stretching surface of non-Newtonian Casson nanofluids with suspended dust particles is due to stretching curved sheets applications across various industries and disciplines, additionally potential applications of dusty nanofluid in various fields. chemical reaction factor is tested in addition to sink and heat sources in the thermal boundary layer. The transformed equations (ODE) are obtained with the help of appropriate similarity variables to facilitate numerical processing. The numerical treatment of the reduced equations is performed employing a numerical technique known as MATLAB function bvp4c to solve our problem equations with the help of the Runge–Kutta method of fourth order. This investigation yields significant conclusions, one of which is that sphere-shaped dust particles in suspension cause the velocity to decrease. That is, the movement declines with the increase in the concentration of dust particles in the fluid. The dust phase’s speed drops, whereas the fluid phase velocity boosts with the curvature factor. Furthermore, the terms skin-friction and the numbers of Nusselt Nus and Sherwood Shs were verified and argued numerically as we found that the Non-Newtonian Casson parameter supports skin-friction. In addition, the liquid–particle interaction factor for temperature increases Nus, and Shs improves with the liquid–particle interaction factor for concentration. The curved stretching surface is recently used in this research to investigate the movement of the boundary layer, as well as the mass and heat transformation properties of a non-Newtonian nano liquid containing spherical dust particles.

EMHD stagnation point flow of dusty hybrid nanofluid over a permeable stretching sheet: Radiative solar applications

The primary objective of this paper is to investigate the impact of dusty hybrid nanofluid electromagnetohydrodynamics (EMHD) on the stagnation point flow in the presence of solar radiation. Base fluids contain ethylene glycol, water, silver, titanium alloy, and suspended dust particles. Nonlinear differential equations with two or more independent variables define fluid flow phenomena. The governing equations can be solved by the MATLAB solver by employing a suitable numerical method, like R–K fourth order via shooting method. The isothermals for various parametric values have been explained. Because it has the potential to greatly advance the disciplines of industrial and thermal engineering, this proposed model is useful. When compared to using a single base fluid, the combination of two additional base fluid qualities provides noteworthy results. Because we were able to acquire a lower freezing point than water and better heat conductivity than pure ethylene glycol when we employed the combination of the two base fluids. Glycol water is used in car coolant and solar heating systems for a variety of purposes. Impact of embedded physical quantities like electric field parameter, ratio of specific heat, porosity parameter, stagnation parameter, radiation parameter, heat source parameter, and fluid particle interaction parameter for both velocity and temperature are illustrated graphically. Dust particles have a notable impact on various sectors, including the food and pharmaceutical industries. Specifically, they are special importance in applications such as wastewater treatment, solids drying, and the presence of plastic-coated metal items. In the present work, we observe that the stagnation parameter enhances the momentum boundary layer (MBL) thickness because the dusty fluid dominates the dusty hybrid nanofluid while incorporating the Ag + Ti alloy/EG + Water. The radiation becomes more efficient at evenly spreading heat, potentially resulting in a more uniform temperature distribution. Silver and titanium alloy particles may affect the thermal conductivity of dusty hybrid nanofluid when compared to the dusty fluid. The porosity parameter enhances the fluid flow and penetration by the porous medium, which lowers friction between the skin and the surface and reduces resistance.

Nonlinear Dust Acoustic Waves in Exosphere of Mercury

The exosphere of Mercury, which has much in common with the exosphere of the Moon, can also contain suspended dust particles, which, under the action of intense solar radiation, acquire positive charges and form one of the components of the dusty plasma system. In addition to dust particles, there are photoelectrons above the planet surface, formed as a result of interaction of solar radiation with the planet surface, as well as with suspended dust particles. Mercury, unlike the Moon, has its own magnetosphere, which affects the parameters of dusty plasma system. The dusty plasma parameters near the Mercury surface can vary depending on the distance from the planet to the Sun, which considerably changes when the planet moves along the elongated orbit, and also depending on the localization of the region under consideration on the planet surface. Thus, near the magnetic poles, the solar wind can reach the planet surface, which must be taken into account when determining the plasma parameters. Far from the magnetic poles, the effect of the solar wind can be neglected. In the dusty plasma near the surface of Mercury, one can expect the development of linear and nonlinear wave processes. In this paper, nonlinear waves are considered, namely, dust acoustic solitons and nonlinear periodic waves. The profiles of potentials of high-amplitude solitons and nonlinear periodic waves are obtained, as well as the soliton amplitudes as functions of the altitude above the planet surface and soliton velocity.

Significant roles of aged dust aerosols on rapid nitrate formation under dry conditions in a semi-arid city

Mineral dust can accelerate secondary aerosol formation under humid conditions. However, it is unclear whether it can promote secondary aerosol formation under dry conditions. To investigate this issue, two years of comprehensive observations was conducted at a semi-arid site, near the dust source regions. Three types of episodes were selected: dust, anthropogenic-dominated, and mixed (mixed with dust and anthropogenic aerosols). Compared to anthropogenic-dominated episodes under humid conditions, rapid nitrate formation was still observed in mixed episodes under dry conditions, suggesting that active metallic oxides in dust, such as titanium dioxide, could promote photochemical reactions of nitrogen dioxide. The detailed evolutionary processes are further illustrated by a typical dust-to-mixed episode. After the arrival of the dust, titanium sharply increased ten-fold and rapid nitrate formation was observed, together with a rapid increase in the two most important photochemical pollutants, ozone and peroxyacetyl nitrate. The increased secondary organic carbon further illustrated that the suspended dust particles accelerated the atmospheric oxidative capacity, thereby enhancing secondary aerosol formation and eventually leading to haze pollution. These results differ from those in humid regions and therefore expand the scientific understanding of the impact of dust aerosols on haze pollution under dry conditions.

Nonlinear stability of two dusty magnetic liquids surrounded via a cylindrical surface: impact of mass and heat spread

The current article examines a nonlinear axisymmetric streaming flow obeying the Rivlin–Ericksen viscoelastic model and overloaded by suspended dust particles. The fluids are separated by an infinite vertical cylindrical interface. A uniform axial magnetic field as well as mass and heat transmission (MHT) act everywhere the cylindrical flows. For the sake of simplicity, the viscous potential theory (VPT) is adopted to ease the analysis. The study finds its significance in wastewater treatment, petroleum transport as well as various practical engineering applications. The methodology of the nonlinear approach is conditional primarily on utilizing the linear fundamental equations of motion along with the appropriate nonlinear applicable boundary conditions (BCs). A dimensionless procedure reveals a group of physical dimensionless numerals. The linear stability requirements are estimated by means of the Routh–Hurwitz statement. The application of Taylor’s theory with the multiple time scales provides a Ginzburg–Landau equation, which regulates the nonlinear stability criterion. Therefore, the theoretical nonlinear stability standards are determined. A collection of graphs is drawn throughout the linear as well as the nonlinear approaches. In light of the Homotopy perturbation method (HPM), an estimated uniform solution to the surface displacement is anticipated. This solution is verified by means of a numerical approach. The influence of different natural factors on the stability configuration is addressed. When the density number of the suspended inner dust particles is less than the density number of the suspended outer dust particles, and vice versa, it is found that the structure is reflected to be stable. Furthermore, as the pure outer viscosity of the liquid increases, the stable range contracts, this means that this parameter has a destabilizing effect. Additionally, the magnetic field and the transfer of heat don’t affect the nature of viscoelasticity.

Significance of Tiny Particles of Dust and TiO2 Subject to Lorentz Force: The Case of Non-Newtonian Dusty Rotating Fluid

This work examined the thermodynamics of the MHD rotating dusty Maxwell water-based nanofluid with suspended dust particles. This study examines the importance of increasing the volume fraction of tiny particles of TiO2 and dust on fluid dynamics. With appropriate similarity transformations, the governing PDEs for both fluid and dusty-phase models are transformed into non-linear linked non-dimensional ODEs. To acquire graphical consequences, the bvp4c technique is implemented in MATLAB scripts. The primary and secondary velocities’ magnitude in both phases decreases with an increase in the dust particle volume concentration, Lorentz force, rotating, and Maxwell fluid parameters. The growing strength of tiny particles of dust and TiO2 is responsible for the upshot of temperature in both dust and nanofluid phases. A visual representation of the Nusselt number and skin friction coefficients are is provided.

STATISTICAL ASSESSMENT OF THE DYNAMICS OF CHANGES IN THE CONCENTRATION OF PM 10 AND PM 2.5 PARTICLES IN THE AIR OF URBANIZED AREAS

This article addresses the issue of atmospheric pollution caused by solid particles in urban environments. The presence of PM10 and PM2,5 particles in the air of major cities and industrial areas worldwide has been examined. An evaluation of atmospheric pollution levels with PM10 and PM2,5 particles in Kostopil, considering current air quality standards in Ukraine and the European Union, has been conducted. The authors employed the gravimetric method to measure the levels of suspended dust particles (PM10 and PM2,5) in Kostopil from autumn 2022 to winter 2023. The study revealed an excessive amount of fine dust particles in the city's air, exceeding the maximum permissible values outlined in regulatory laws by 2.1-2.7 times. Furthermore, the monitoring of changes in suspended dust particle levels showed peak values of PM10 = 1.15 mg/m³ in January and PM2,5 = 0.96 mg/m³ in December. The results of the statistical analysis of particle level distribution in Kostopil's urban areas indicated the statistical significance of certain distribution parameters, specifically SW-W and D for PM10 and PM2,5 particle classes.

ON THE EQUILIBRIUM OF STRATIFIED VISCOELASTIC PLASMA WITH QUANTUM PRESSURE AND SUSPENDED PARTICLES SATURATING POROUS MEDIUM

Stability of stratified incompressible viscoelastic plasma arranged in horizontal strata with quantum pressure and dust particles saturated by a porous medium is investigated. The rheology of the plasma is described by the Walters (model B). The set of non-linear partial differential equations defining the physical system are reduced to linear ordinary differential equations by using the perturbation method, linear theory and normal mode technique. The density, viscosity, viscoelasticity and quantum pressure are assumed to stratify exponentially along the vertical, to obtain exact solutions satisfying the physical boundary conditions and the dispersion relation. The values of growth rate of the unstable perturbed modes are computed numerically to investigate roles that the various variables play on the stability on the considered physical system and are shown graphically. It is observed that the suspended dust particles density and relaxation time factor have a destabilizing effect on the system; whereas viscoelasticity in the presence of suspended dust particles lead to more damping in the frequency of perturbed waves. This work finds applications in diverse fields viz. modern technology, industries, astrophysics, petroleum oil additives, equipment of aero planes etc.

Promoted Activity of Surface Hydroxyls on γ-Al2O3 Mineral Dust with the Coexistence of SO2 and NH3.

Sulfate and ammonium formed on mineral dust can be mutually accelerated through the heterogeneous reactions of coexisting SO2 and NH3. However, little is known about the underlying mechanism, especially the pivotal reactive sites. Using combined Born-Oppenheimer molecular dynamics simulations and density functional theory calculations, the results show that, compared to that of SO2 or NH3 alone on the γ-Al2O3 surface, the increased level of formation of sulfate and ammonium can be attributed to the promoted activity of the surface-bridged hydroxyl with the coexistence of SO2 and NH3. In the specific mechanism, the O and H of the surface-bridged hydroxyl group are attacked by the adjacent SO2 and NH3, respectively, which directly enhances the formation of absorbed sulfite and ammonium, and indirectly facilitates the production of sulfate by oxidation of atmospheric O2. The proposed mechanisms can be broadly applied to other aluminum-based suspended dust particles, such as kaolinite, montmorillonite, and clay dust.

Simulations of Dusty Flows over Full-Scale Capsule During Martian Entry

Suspended dust particles can have adverse effects on heat shields during Mars atmospheric entry. For instance, they can increase both surface heating and surface recession. Current studies on this subject often make many simplifications, focus on a specific physical process, or include flow conditions different from those on Mars. To address this, we perform computational fluid dynamics simulations of hypersonic dusty flows over a full-scale entry capsule based on a realistic flight trajectory. The simulations are performed with an Euler–Lagrange methodology in which the carrier gas solution is obtained with a discontinuous Galerkin method. We employ a recently developed physics-based drag correlation that obtains better agreement with experimental data than popular existing correlations. To improve understanding of the relevant physical processes, which are still not very well understood, the effects of various factors, such as particle size distribution, angle of attack, and two-way coupling, on dust-induced heating augmentation and erosion are assessed.

Significances of magnetic dipole flow and melting heat transfer over suspended dust particles along with carbon nanotubes

The current research letter is materialized to examine the combined effect of thermophoretic dust particle diffusion and magnetic dipole flow toward a stretchable sheet. The slip effect is used in the development of the momentum equation. Water is considered as a base fluid, and single-walled carbon nanotubes and multiwalled carbon nanotubes are nanoparticles. The aforementioned rheological model is formulated in the way of nonlinear partial differential equations (PDEs). The structure of nonlinear biformed ordinary differential equations (ODEs) is obtained from the modeled nonlinear PDEs by incorporating valid sameness transformations. The system of ODEs is then figured out by employing the tool of MATLAB function bvp4c. The significant nature of the contributing parameter for both the single-wall and multiwall cases is presented via graphs. From the results, we conclude that an impact of the melting effect, mounting of Pr, reported a thinner thermal boundary layer thickness. Furthermore, a clear rise of nanofluid temperature is noticed for the greater melting M1 parameter. The slip parameter plays a significant role in the enhancement of the velocity profile.

Detecting dust loads in the atmosphere over Thar desert by using MODIS and INSAT-3D data

• Dust detection algorithm based on MODIS and INSAT-3D were developed for Thar desert. • Brightness temperature difference and dust indices were used to detect dust load. • Integrated dust detection approach using MODIS and INSAT-3D was complementary. • Dust load detection over Indian Thar desert was successfully validated and tested. Suspended dust particles in atmosphere have adverse impacts on environment, ecosystem as well as on human health. To avoid negative impacts of dust storm events, early warning system to predict it well in advance may be a suitable option. However, for this purpose, assessment on magnitude of dust load and its dynamics in atmosphere is a primary requirement. The present study aims to develop remote sensing based assessment of dust load in atmosphere specifically over the Indian Thar Desert region. The severe dust storm event occurred on 5 th June 2017 over the Indian Thar Desert has been used in this study to develop integrated dust detection algorithm using split window technique, mid-infrared technique and different dust indices derived from MODIS and INSAT-3D data. Evaluation of the developed algorithm revealed that the area classified under dust load depends on threshold value of dust indices used in the algorithm, type of dust detection techniques followed and the specifications of remote sensing sensors used to retrieve the dust image. The integrated dust detection algorithm developed in this study has the capability to eliminate the problem in variations of predicted dust loadings in atmosphere. Validation of the developed algorithm to detect dust pixels showed good agreement with independent observations on aerosol optical depth (AOD), wind speed profile data and ground visibility data. The method adopted can be helpful to implement an operational system for detection and monitoring of dust storms over the Thar Desert region.

Impact of dust accumulation on the physiological functioning of selected herbaceous plants of Delhi, India.

Plants are now widely recognized for their potential role in improving the air quality by dispersion and deposition of atmospheric dust particles. However, suspended dust particles negatively affect plant growth and physiological development. The present study aims to assess the amount of dust accumulation on the leaf surface and to evaluate the effect of foliar dust on leaf gas exchange parameters, photosynthetic pigment, and metabolite content of five roadside herbaceous plant species (Amaranthus viridis, Achyranthes aspera, Acalypha indica, Parthenium hysterophorus, Trianthema portulacastrum). Two sites (site I and site II) were selected that differed in their surrounding anthropogenic activities and dust pollution levels. Results showed that the average amount of dust accumulated on the leaf surface was significantly greater in plants grown at the polluted site. Among the five species examined, the highest amount of foliar dust load was observed for A. aspera (0.49mgcm-2). Dust accumulation caused substantial changes in plant physiology as indicated by the significant decline in chlorophyll content, photosynthetic rate, stomatal conductivity, and transpiration rate in plants grown at the polluted site. Moreover, an increase in antioxidant activity, total ascorbate, and metabolite content, responsible for maintaining plant defense, was higher in plants at polluted site. Biochemical response of the individual plants studied was variable, which suggests that different plants adopted different mechanisms to cope with the stress induced by dust particles.

Usage of Atmospheric Sounding to Characterize the Meteorological Events on the Night of 23/24 August, 2022

Abstract At the end of summer, the episode of atmospheric instability in the Moldavia region, is attributed to the predominantly eastern circulation, which directed air masses from the Asian continent to Romania. This context is the result of the presence of a high-pressure area, located in northern Siberia and extended to north-eastern Europe. Romania was located in the flow of the eastern circulation, behind the warm front. The emersion of unforeseen factors, as was the case with the transport of dust from the dry regions of Asia, due to background of a circulation from the east, or the specificities of the relief, make it difficult to forecast the phenomena associated with instability. In this sense, atmospheric soundings are among the most used tools in forecasting atmospheric instability. In this sense, we used atmospheric soundings estimated by the GFS and ECMWF numerical forecast models to analyze the atmosphere vertically. Also, the cross-section profiles drawn in the EUMeTrain application showed the differences between the west and the east of Moldavia and described the vertical atmosphere in the analysed interval. The evolution of the convective episode was described through satellite images. The forecast models anticipated the instability but did not estimate the amounts of cumulative precipitation. The increase in the amount of precipitation was, among other things, attributed to the existence in the atmosphere of Moldavia of dust particles that acted as condensation nuclei that increased the amount of precipitation. High concentrations of dust were also noticed after consistent rain showers, as explained by Cloudnet data processed. The analysed case was one of the most representative instability episodes for summer of 2022 in Moldavia and played a decisive role in the soil water reserve. Here’s how air quality and changes in the atmosphere have a major impact on the environment. The notable frequency of detected electrical discharges, was probably also the result of the presence in the atmosphere of suspended dust particles (due to a natural air pollution process), driven towards the Moldavia region.

An extensive dust storm impact on air quality on 22 November 2018 in Sydney, Australia, using satellite remote sensing and ground data

Recurrent dust storms represent a significant concern in Australia because of their related hazards and damages since particulate matter (PM) has harmful impacts on the environmental, health and economic sectors. The particulate matter may be released from natural sources and human activities. The major part of natural particulate matter is emitted into the air by wind erosion processes from desert and semi-desert areas at the world scale. A huge dust storm crossed over several areas of New South Wales (NSW), Australia, including the Sydney region on 21–22 November 2018 and decreased the horizontal visibility to less than 1 km for 22 h. This study examined the synoptic weather conditions, and assessed the air quality and identified the source and transport trajectory of the dust storm over Sydney using ground and satellite remote sensing data. PM10 (< 10 μm) concentrations were obtained from selected air quality monitoring sites operated by the Environmental Protection Agency in NSW. The highest hourly concentration of PM10 (578.7 μg/m3) was recorded at Singleton in the Hunter Valley, while concentrations in Sydney ranged from 480 to 385 μg/m3, well above the standard air quality level in Australia (50 μg/m3 per 24 h). The HYSPLIT back trajectories of air parcels suggest that the potential sources of the dust episode originated from the Lake Eyre Basin and northeast South Australia, the Mundi Mundi plains west of Broken Hill, Cobar and the grazing lands and the red sandplains in northwestern NSW. It then travelled towards the east coast. These long-range airflows transported suspended dust particles, raising air quality to hazardous levels (elevated PM10 levels) over most areas of NSW. The results from the HYSPLIT model for dust movement are confirmed by MODIS satellite images. Many areas of NSW experienced this intense dust storm due to northwest wind generated by the low-pressure systems and cold fronts over South Australia and many parts of western NSW as it moved eastward.

Detection of fungi and yeast in the air dust outdoors of the city of Morelia, Mich, Mexico

The air we breathe contains suspended dust particles which can host filamentous fungi that can cause respiratory problems and allergies in humans. Generally, the propagules can survive depending upon the environmental conditions, such as humidity, temperature and cleanness. The aim of this research work was to detect the fungi in dust of outdoor air at the city of Morelia, Mich, México. So far similar study is not reported in this city. For this purpose, the samples were collected at fixed places from October to December 2017 at two times during the day. Results demonstrate the existence of the various fungi genera, from high to low concentration levels: Aspergillus fumigatus, Penicillium sp, A. niger, Monilia sp, Alternaria sp, Mucor sp, Acremonium sp Cladosporium sp, and Chrysosporium sp including more than one genus of yeasts such as Candida tropicalis and Rhodotorula rubra were isolated from the dust precipitated from the outside air, regardless of the intensity of solar radiation The existence of A. fumigatus and C. tropicalis represents a risk for human population who lives in this city in that sense a sanitary measures should be apply.

Turbulence in the Lower Atmosphere of Mars Enhanced by Transported Dust Particles

AbstractA recent article by Wu et al. (2021, https://doi.org/10.1029/2020JE006752) reports unprecedented turbulence‐resolving numerical simulations for Mars, in which the radiative impact of suspended dust particles transported in convective circulations is resolved for the first time. Those simulations demonstrate that in certain conditions, a dustier Martian atmosphere may result in stronger turbulence and mixing in Mars' planetary boundary layer, as a result of the inhomogeneity in the distribution of dust particles being reinforced by turbulent convective cells. This effect competes with what was hitherto thought to dominate in a dustier atmosphere, that is, a turbulence weakening related to surface shading by suspended dust particles. Wu et al. (2021 https://doi.org/10.1029/2020JE006752)'s work has many implications for future studies of Mars' meteorology and climatology.
