Analysis of Hail Causes in Wafangdian City on May 20,2014
摘要
Abstract
Hail disaster conventional data and hail census data in Wafangdian City from 1951 to 2009 were analyzed.Using MICPS conventional observations,zone automatic observation stations live,satellite images,radar puzzles with topographic features,we analyzed the hail causes in Wafangdian City on May 20,2014.The results showed that Chaoyang,Dandong and Shenyang were hail-prone land,Wafangdian area was one of the hail disaster-prone area in Liaoning Province;Wafangdian region had the largest hail in June,followed in September.Ascending movement caused by weather systems of upper trough line,low-level shear line radiation,is the strong convective weather trigger mechanism;Southwest jet provided water vapor for short-term heavy rainfall,increased magnitude of heavy precipitation;’Trains effect’ was an important factor to produce heavy rain,prompted hail,thunderstorms and other severe convective weather short-term strength increase;Terrain and wind uplift mountain slope were the driving force of this hail weather conditions occur;upward motion caused by back storm,generated new convective clouds in valley were the main reason for the region’s large hail.关键词
