| 摘 要： | 利用NCEP 1979—2003年1~12月再分析的OLR逐日、月平均资料及同期云南雨季开始期资料,通过相关统计、对比合成等方法,重点分析了南海和孟湾海区的OLR场变化对云南雨季开始期的影响。结果表明,南海和孟湾海区OLR在云南雨季开始偏早年与偏晚年之间差异明显,南海海区前期的对流活动对云南雨季开始期有更显著的指示性,但孟湾海区对流的强弱仍是影响云南雨季开始期的重要因素之一。

| Abstract: | Using the OLR data of NCEP reanalysis value from 1979 to 2003 and the rainy season onset data of Yunnan Province,the influence of OLR over South China Sea and Bay of Bengal on the rainy season onset of Yunnan Province are analyzed.It is found that the OLR over South China Sea and Bay of Bengal is obvious difference in earlier and later years of the rainy season onset of Yunnan Province.There is a very close relationship between the rainy season beginning of Yunnan Province and the OLR over the South China Sea more than the OLR over the Bay of Bengal,but the influence of convection of Bay of Bengal on the rainy season beginning of Yunnan Province is still important. |
