| 摘 要： | 利用GEOS-9卫星红外1云图对2003年6月21日至7月22日淮河流域大水期间的MCS做了普查分析.结果发现：（1）淮河大水期间共有10个MαCS和24个MβCS,其产生频数远大于常年的平均值;（2）绝大部分MCS初生于淮河流域并且其成熟时的位置位于淮河流域是造成这次大水的主要原因之一;（3）淮河流域大水期间部分MCS的形成时间与一般MCS有所不同.最后,结合常规资料对产生MCS的天气背景进行了分类,发现该期间MCS形成的天气背景具有多样性.

| Abstract: | Based on the GOES-9 satellite IR images during inundation from 21 June to 22 July 2003, the mesoscale convective systems are investigated over the Huaihe River region. The results revealed: (1) There are total 10 and 24 , the frequency is much larger than the average of an ordinary year. (2) The large number of MCS originated and maturated in Huaihe River region is a main cause of this inundation. (3) The formation time of some of MCSs is different from general MCS. (4) The synoptic environment conditions of the MCS are various. |
