THE MESOSCALE CONVECTIVE SYSTEMS DURING IOP608 OF HUAMEX

National Laboratory for Severe Storm Research, Department of Geophysics, Peking University, Beijing 100871, China

摘要

摘要: 给出了海峡两岸及邻近地区暴雨试验1998年6月7～10日加密观测期的日平均红外云图的云顶亮温T_BB的分布,并通过对逐时红外云图的普查共发现了14个中-α尺度的对流系统和若干个中-β尺度对流系统。重点分析了6月7日和9日给台湾中部和珠江口带来暴雨的多个中尺度对流系统连续发生过程及其发生的环境条件。利用可视化系统LiveView展示出了高、低空水平风场和垂直环流之间的联系及湿空气运动的三维轨迹。

Abstract: Given the distributions of the daily mean temperature of black body of satellite infrared images from June 7 to June 10,1998 during HUAMEX,fourteen meso-α-scale convective systems and a number of meso-β-scale convective systems are examined using the satellite infrared images in 1 hour interval. The mesoscale convective systems on June 7 and June 9,which resulted in severe rainstorm over the middle of Taiwan and the estuary region of Zhujiang River,are emphatically analyzed. The serial development of mesoscale convective systems is revealed by the distributions of the black body temperature of satellite infrared images. The environmental conditions that many mesoscale convective systems continuously occurred are diagnosed. The visualizing tool,LiveView,displays the link between the upper and lower horizontal wind fields and vertical circulations,and 3-dimensional trajectories of moist air motions,based on the data of objective analyses.
