摘要
利用NCEP/NCAR再分析资料和TBB资料对华南暴雨与亚洲两支越赤道气流的关系进行了探讨。分析结果表明华南暴雨与亚洲两支越赤道气流的变化联系紧密 ;在华南暴雨发生前 ,在索马里和 10 5°E赤道附近存在经向风扰动增强现象。阿拉伯海地区和孟加拉湾地区的风速在华南暴雨发生前逐渐增强。另外还发现华南暴雨发生前华南地区存在季风涌过程。
By using the NCEP/NCAR reanalyzed data and TBB data, the relationship between the Asian tropical monsoon and the heavy rain in South China is studied.The main results are as follows.The heavy rain in South China has close relationship with the Asian tropical monsoon.The northwards cross-equatorial flow at the area of 105°E has an intensification course prior to heavy rain,so does the velocity in Bengal gulf and in the Arabia sea.Prior to heavy rain ,there is a monsoon surge in South China.
