Abstract
Data visualization uses charts, graphs and maps to illustrate some information. Visualizing data helps us understand information faster. The study of droplet dynamics is a critical part of cloud physics and includes studying droplet properties. The aim of this work is to visualize the droplet dynamics obtained from DNS (Direct Numerical Simulation) data due to evaporation and condensation of the droplets. This simulation contains coupled Eulerian and Lagrangian frames. Animation is created for both Eulerian grid data and Lagrangian droplet movement. Scientific visualization provides a way to analyze these turbulent properties in a part of a cloud and learn about the nature of droplets and mixing process in such highly turbulent areas.

Weather forecasting centers manage a large amount of meteorological data
It is difficult to examine the properties by just looking at Direct Numerical Simulation
This work shows, the data obtained from Direct Numerical Simulation of entrainment and mixing processes in cloud affect the droplet dynamics due to condensation and evaporation
Summary
Weather forecasting centers manage a large amount of meteorological data. This work shows, the data obtained from Direct Numerical Simulation of entrainment and mixing processes in cloud affect the droplet dynamics due to condensation and evaporation. The turbulent entrainment and mixing of dry air with moist or cloudy air influences the cloud's lifespan by changing the properties. Such modifications are responsible for the droplet dynamics. This mixing process is quite complex, and it is difficult to study it during field observations It illustrates how all of the droplets will evaporate by the same number, or the subset of the droplets evaporates entirely, while the other droplets remain intact in the cloud turbulence. This work uses ParaView for visualization because of its ability to analyze extremely large datasets rather than using expensive commercial software
