Abstract:
Based on the relevance between the number of the stations where had a hail weather in the northern Fujian and the physical element fields from 2003 to 2005, the physical factors closely related to hail weather in different seasons (March to April in spring, and May to June in flood season) in the northern Fujian are identified. In combination with the numerical physical element forecast products of T213 and the actual physical element products summarized from the practical forecast experiences of several years in Fujian, the objective forecasting system of hail weather for different seasons in the northern Fujian is established by using the index superposition method. This system achieved good result in operation from 2008 to 2010, in which there was no missing alarm and very low false alarm rate after using the unique elimination conditions in the model.
