Every year, the number of weather anomalies is growing everywhere. This summer was also marked by squally winds that swept through many regions of the Russian Federation at the beginning of the calendar summer: the hurricane that swept through Moscow caused not only serious multimillion-dollar material damage, but also injured and killed people. It should be recalled that storm winds include squalls and tornadoes, which are dangerous hydro meteorological phenomena. According to the classification proposed by the International Committee of Meteorology such winds are measured in points, where 8 points wind – storm, strong wind with speed of 20 m/s, which hampered any movement against the wind; 12 points – hurricane speeds over 29-33 m/s. Squally winds are accompanied by powerful cumulonimbus clouds. Such cloud formations are called mesoscale convective systems (MCS). The formation and formation of the ISS is related to atmospheric physics, where powerful dynamics of cold air mass and vertical wind shear are observed against the background of static stability. It is important to emphasize that the force of Gale-force winds carries great destructive power, despite the short-term impact
