Abstract
The causes of aircraft crashes were investigated for several accidents, such as the Tu-154 and the Airbus A320-211 crashes near Sochi, Russia; the Airbus A320-232 crash near the Perpignan airport; and the Airbus A310-324 crash during landing in Moroni, Comoros Islands. Failures related to aircraft aerodynamics caused these air catastrophes. Upon encountering an upward vertical front, the airstream over the plane wing was disrupted and, as a result, the aerodynamic lifting force suddenly and dramatically decreased. The critical value of the vertical wind speed in a sea-land front (SLF) was determined to be ~0.5–1.0 m s−1. Some recommendations are proposed to prevent such aircraft accidents near coastal airfields. Forecast predictions of a sea-land breeze w-Front and of MWT (Mountain Wave Turbulence) were performed by regional atmospheric models with a resolution no lower than 2 km. Further, a possible reason for the sudden disappearance of aircraft near the coast of Florida is suggested.

During take-off, a Tu-154B-2 aircraft with the serial number RA-85572 crashed on December25, 2016, after refuelling at the intermediate airport in Sochi/Adler, Russia
Since the crash of the aircraft was at the land–water interface, much attention has been paid to studying the Sea Breeze Circulation (SBC) for the time of the aircraft crash
Summary
During take-off, a Tu-154B-2 aircraft with the serial number RA-85572 crashed on December. It is generally thought that, at high altitudes, with exception the only exception beingflying aircraft flying storm fronts, w-Fronts are not a frequent phenomenon Mesoscale meteorology is applied to predict such phenomena as thunderstorms, mesoscale convective systems (MCSs), tropical storms, land/sea breezes, mountain/valley breezes, downslope windstorms, gap flows, cold air damming, nocturnal low-level jets, lake-effect snow bands and others. Regional meteorology with a resolution of 6–8 km can describe such atmospheric phenomena as sea-land circulations, mountain turbulence, secondary phenomena in convective currents (CIT), small circulations in cyclones and many others. The goal of this work is to study the various meteorological situations observed during aircraft crashes by using a regional model, as well as to identify the causes of these crashes and to develop recommendations for flight safety. The calculation of the aerodynamic lift force, which depends on the wing profiles, is beyond the scope of meteorology and is not considered in this study
