Abstract: 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_αCS influencing on the Korea Peninsula.

摘要： 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(M_αCS)的发生情况。结果表明，该地区是一个M_αCS的多发区，并且M_αCS的发生发展具有一定的间歇性。影响该地区的M_αCS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M_αCS在海洋之上消散；只有少数的M_αCS对朝鲜半岛有影响。
