中文摘要：

华南海西南季风(SCSSM ) 的活动在雨季期间在广东省在重要天气的异例上有直接影响。彻底地在省探索有重要天气异例的 SCSSM 和它的关系的活动模式因此是必要的。在这份报纸，合成分析和关联统计的方法被用来学习在发作日期和 SCSSM 和重要天气的紧张之间的关系，例如在广东省在期间的 降水趋势每年第一和第二雨季，预定每年首先并且上次台风和在广东登陆的台风的数字省。降雨是的结果表演不到在第二期间在第一雨季期间正常，却非常正常并且有更热带的气旋，在早 SCSSM 的年里在广东省登陆发作。降雨在第二雨季期间多于正常，有更热带的气旋，在强壮的 SCSSM 的年里在广东省登陆。在 4 月的 SST 之间的关系 -6 月， 7 月 -9 月和以前的冬季(12 月 -2 月) 并且 500 hPa geopotential 高度和发作日期和 SCSSM 的紧张被分析。在发作日期和在广东省的 SCSSM 和重要天气异例的紧张之间的一些机制 preliminarily 被探索。结果能在短期的气候预报被用于参考。

英文摘要：

The activity of South China Sea southwest monsoon （SCSSM） has direct impacts on the anomalies of important weather in Guangdong province during the raining seasons. So it is necessary to explore thoroughly the activity pattern of SCSSM and its relationship with important weather anomalies in the province. In this paper, the methods of composite analysis and correlation statistics are used to study the relationship between the onset date and intensity of SCSSM and the important weather, such as precipitation trends in Guangdong province during the annually first and second raining seasons, the timing of the annually first and last typhoon and the number of typhoons landing in Guangdong province. The results show that the rainfall is less than normal during the first raining season, but more than normal during the second one and there are more tropical cyclones landing in Guangdong province in the years of early SCSSM onset. The rainfall is more than normal during the second raining season and there are more tropical cyclones landing in Guangdong province in the years of strong SCSSM. The relationship between the SST of April - June, July - September and previous winter （December - February） and 500 hPa geopotential height and the onset date and intensity of SCSSM is analyzed. Some mechanisms between the onset dates and intensity of SCSSM and the important weather anomalies in Guangdong province are preliminarily explored. The results can be used for reference in short-term climate forecast.
