Analysis on Radar Echo Characteristics of Hail Clouds in Spring and Summer of Anhui Province
摘要
Abstract
Analysis of the hail echo artificial in Anhui in spring and summer is important for hail preven-tion.By using the hail data collected in Anhui during 2002 - 2013,CINRAD data,the Storm Cell Identification and Tracking (SCIT)algorithm,we got 59 hail processes from March to August and ana-lyzed statistically the echo intensity and height of hail clouds,and VIL.The results show that hail proba-bility is the greatest in June and July,especially in from afternoon to evening (15:00-18:00 BT).Over the Anhui Region,hail echo intensity of spring and summer is at least 55 dBz,mostly is 60-70 dBz,VIL is at least 30 kg·m-2 ,mostly is 40-80 kg·m-2 .The varying trend of VIL is similar with the maximum reflectivity,and their maximum values tend to occur near the onset time of hail.The average echo top of hail storm is 13.6 km in spring and summer,average top storm height of 30 dBz is 12.1 km and the maxi-mum echo top height is above 17 km.关键词
