2、析了华南前汛期降水异常与水汽输送的关系,并对旱、涝年进行了比较分析。结果表明:华南地区经向水汽输送的异常变化将导致该地区的异常旱涝,而纬向水汽输送的异常变化只导致该地区出现小范围的降水异常。旱年和涝年的异常水汽输送不是简单的反位相关系。来自印度洋和西太平洋的水汽对华南地区前汛期的降水异常没有明显的作用,南海(主要是其北部)才是华南降水异常的关键区。 关键词:华南前汛期;水汽输送;降水异常,(1),4,An analysis on the relation between the precipitation anomaly of the first flood period in south C
3、hina and the water vapor transportation Abstract: The relation between the precipitation anomaly of the first flood period in South China and the water vapor transportation is analyzed by using the daily precipitation data of 57 stations in South China and the NCEP/NCAR reanalysis daily data for wat
4、er vapor transportation form 1958 to 2000, and the differences between the drought year and flood year are studied. The results show that the meridian anomaly of water vapor transportation in south China causes drought or flood of south China, but the longitudinal anomaly only cause local precipitat

9、na and the NCEPNCAR reanalysis daily data for water vapor transportation form 1958 to 2000. Results show that the anomalies of meridianal water vapor transportation in south China is responsible for the widespread drought or flood over that region, while the zonal transport changes only cause precip
10、itation anomalies in a smaller or local areas, and that the water vapor transportation feature in drought years is not simply just an out-of-phase contrast to that of flood years. Evidence further suggests that it is not the water vapor coming from the Indian and Western Pacific Oceans, but that fro
11、m the key area of South China Sea, particularly its north part, that plays an critical role in causing the precipitation anomalies during the first flood period in South China.
