1993～1996黄海及其周边地区M_αCS的普查分析

Meso-α-Scale Convective Systems over Yellow Sea Region during Summers of 1993～1996

使用日本GMS静止卫星红外云图普查了 1993～ 1996年夏季黄海及周边地区中 α尺度对流系统 (MαCS)的发生情况。结果表明 ,该地区是一个MαCS的多发区 ,并且MαCS的发生发展具有一定的间歇性。影响该地区的MαCS多数发源于大陆 ,但也有相当数量发源于海洋上 ,发源于朝鲜半岛的较少 ;有一半以上的MαCS在海洋之上消散 ;只有少数的MαCS对朝鲜半岛有影响。

Based on the GMS satellite IR images during the summers of 1993～1996,the meso-α-scale convective systems (M αCS) were investigated over the Yellow Sea region.The results revealed that the Yellow Sea region is a favorable zone for M αCS in eastern Asia and there exist active-M αCS period and null-M αCS period during summer in the region.The majority of M αCSs originated from the mainland of China,while the minority from the ocean and few from the Korea Peninsula.More than half of M αCSs dissipated over the Pacific Ocean,and there was few M αCSs influencing on the Korea Peninsula.
