| Abstract: | Aiming at the heavy snow weather process occurred in Hinggan League on December 9, 2010, this paper analyzed the sequencing of this heavy snow weather process in every, meteorological station in history and it＇s impact for white disaster. The influence of the relative humidity, vorticity, divergence, vertical velocity and wind field in physical quantity field for this heaW snow weather process were analyzed in the aspects of the influence system of high altitude circulation feature, the distribution characteristics of wind field and the moving direction and location of ground infrabar. Finally, the forecast effect of numerical forecasting products in Europe and T639, Germany and Japan grid precipitation, Japan fax diagrams were tested. |
