METHOD OF DEFINING METEOROLOGICAL PARAMETERS

FIELD: physics. ^ SUBSTANCE: current values of a true wind, atmospheric pressure, temperatures and humidity of air, height of the bottom border of clouds and meteorological visibility range are determined. Meteorological parameters are forecasted at the observation points spaced apart to reveal dangerous and especially dangerous phenomena. Said points of observation are equipped with a meteoradar apart from the other equipment. In analysing the content of abnormal values, hydro meteorological information from meteorological artificial satellites is additionally used. The forecast of meteorological parameters is executed by constructing a semiempirical model of fluctuations of streams and disturbances depending upon wind speed, direction and duration at least three high-altitude echelons. In forecasting the dangerous and especially dangerous phenomena, additive parameters distribution charts are plotted and the phenomena, defined by distribution of abnormal values of additive parameters are identified. The content of abnormal values is analysed by comparison of the measured meteorological parameters at each observation point. The change of increments of parameters in time allows determining the direction of movement of the dangerous phenomena. Note here that the measured meteorological parameters obtained with the help of meteorological station with greater meteorological potential are taken to be reference values. ^ EFFECT: increased forecast reliability, expanded performances. ^ 1 dwg
