Abstract: | A method of forecasting the heavy convective precipitation zones is based on the computation of the Q-vector divergence and moist equivalent-potential vorticity in the layer from 925 to 700 hPa. The prognostic fields of meteorological parameters from NWP models in GRIB or GRIB2 codes are used for the computation. Presented are the results of the statistical analysis. The coefficients of linear regression are computed and the working equation for forecasting heavy convective precipitation zones during the cold season is derived. Analyzed are some heavy snowfalls in the central region of the European part of Russia. |
