Rossby波列传播效应在梅汛期强降雨中期预报中的应用研究
An Applied Research About Spread Effects of Rossby Wave in Medium-Range Forecast on Heavy Rain During Meiyu Flood Period
摘要
Abstract
This paper primarily discusses the synoptic and climatic characters in heavy rain during Meiyu flood period (June--July) based on the thirty year (1981--2010) observational data at 46 stations and the reanalysis dataset from 1981 to 2010. Main circulation characters and impacting systems of heavy rain in Jiang Huai Basin at 500 hPa and wind distribution characters at 850 hPa are summarized by integratively analyzing abundant historical examples. A conceptual model of heavy rain and study respects of medium range forecast are put forward. Ten durative heavy rain weather processes in the last thirty years are dis cussed, and the results show that the easterly propagation of Rossby wave is in favor of occurrence of the durative heavy rain weather processes in Jiang-Huai Basin. The downstream development of Rossby wave provides some new ideas for medium range forecast.关键词
