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

Key words: Meso-α-scale convective system, Yellow Sea, investigation

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(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。
