ON THE POSSIBILITY OF FORMULATING PROGNOSTIC SIGNS OF DANGEROUS ATMOSPHERIC PHENOMENA BASED ON THE ANALYSIS OF VARIATIONS IN GEOPHYSICAL FIELDS

We discuss a new approach to the development of a comprehensive prognostic feature of atmospheric fronts causing dangerous atmospheric phenomena in the form of hurricanes, squalls, severe thunderstorms and volley precipitation. Our approach is based on the analysis of joint variations of meteorological parameters of the atmosphere and geophysical fields (primarily electric and magnetic fields) in the period preceding the arrival of the front and the onset of the most intense phase of these dangerous phenomena. It is shown that 5‒8 hours before the arrival of powerful atmospheric fronts of the 2nd kind, variations in the geophysical characteristics of the surface atmosphere are observed, which can be used as the basis for the formulation of prognostic signs of dangerous atmospheric phenomena. The data provided can be used to prevent negative consequences and increase the reliability of short-term forecasting of negative effects of atmospheric phenomena.
