龙门山脉东麓一次强风暴灾害气象特征分析
Analysis on Meteorological Characteristics of a Strong Storm Disasters in the Eastern Foot of Longmen Mountain
摘要
Abstract
Using surface observation data,sounding data and Doppler radar data,the high precipitation supercell storm occurred in Deyang Sichuan Province in the night of 5 May 2016 is analyzed in detail.The sounding data before the storm show some severe convective weather characteristics such as heterogeneous structure through the whole aerosphere,wasp waist structure in the middle layer,roll-flow wind field in the almost layers and cooling layer at the troposphere.Storm possesses a inflow V-notch,bounded weak echo region (BWER) at middle level and mesocyclone which develops from middle level to low level and high level.The evolution of vertically integrated liquid and vertically integrated liquid density are a significant signal to the formation and attenuation of hails which accompanied by heavy rain and surface gale.关键词
