摘要
利用全球NCEP/NCAR资料,采用诊断分析方法,对2003年夏季6月29日～7月4日发生在淮河流域的特大暴雨过程成因进行了分析.结果表明:暴雨出现与大气环流异常以及水汽输送、西南季风的异常偏强有关;暴雨区的水汽来源于阿拉伯海至孟加拉湾及北太平洋至中国南海地区.
An analysis was made on the causes of heavy rains that occurred in the Huaihe River Basin from June 29 to July 4 of 2003 by use of the global NCEP/NCAR data and the diagnosis analysis method. The results show that the occurrence of the heavy rains is mainly induced by the abnormity of atmospheric circulation, moisture transport, over-mightiness of southwest monsoon, and that the water vapor of the rainy zones mainly comes from the regions from the Arabian Sea to the Bengal Gulf and from the north Pacific Ocean to the South China Sea.
