Analysis on A rainstorm in Aug.4, 2012 in Puyang City
摘要
Abstract
By using routine sounding, encryption ground data, satellite cloud map and new generation weather radar products, a diagnosis analysis was conducted on a heavy rainstorm formed by Sula typhoon inverted trough during Aug. 4-5, 2012. The result suggested that: the ty-?phoon, subtropical high and North China high caused the heavy rainfall process, that is typical of low latitude systems interaction process. The east side of the inverted trough the rainstorm area southeast LLJ from the low-latitude sea transport of heat and moisture, at the same time, become a source of strong mesoscale convective systems in its left front. A marine generate new typhoon westward movement approaching typhoon airflow superposition of heavy rainfall. The rainstorm area locate on back side of strong convergence area below a convergent line of α mesoscale close anticyclone in 200 hPa high level jet right rear side, and left frontage in 700 hPa southeast low level jet. Mighty and steady subtropical high run out south of North China from Yellow Sea and Bohai Sea, which blocks off the west precipitation system and leads that β mesoscale rainstorm cloud clusters move slowly which park, rotate, develop in northeast of Henan for a long time conducing local heave rainfall.关键词
