METHOD FOR DETERMINING THE STABILITY CLASS OF THE ATMOSPHERE BY MEASURING METEOROLOGICAL PARAMETERS BY AN UNMANNED AERIAL VEHICLE Russian patent published in 2021 - IPC G01W1/08 

FIELD: meteorology.

SUBSTANCE: invention relates to the field of meteorology and can be used to determine the class of stability of the atmosphere. An unmanned aerial vehicle (UAV) moving under the influence of the wind and equipped with navigation and meteorological instruments is launched into the area of ​​interest. The wind speed and air temperature are measured at an altitude of 100 m, the wind speed and the swing of the wind direction at an altitude of 25 m. Wherein, the UAV in the horizontal plane is directed along several routes intersecting at one point. At the same time, directly under the point of intersection of the UAV routes, measurements of wind speed at a height of 10 m and air temperature at a height of 2 m are carried out by means of a mobile meteorological kit, which is placed considering the orography. The received data is automatically transmitted via radio communication channels with a given discreteness to a ground-based computer complex. The stability parameter is determined as the ratio of the averaged values of the air temperature at heights of 2 and 100 m and the wind speed at heights of 10 and 100 m. Taking into account a certain stability parameter, data on the wind speed and the amplitude of wind direction fluctuations at an altitude of 25 m, the atmosphere stability class according to Pasquill is determined.

EFFECT: improving the accuracy and efficiency of forecasting environmental pollution by harmful impurities from emergency sources remote from equipped meteorological sites.
