摘要 利用NVAP-M卫星资料和ERA-I再分析资料分析了1979—2008年海南岛夏半季、冬半季和年平均大气可降水量(PW)的时空分布特征及异常年成因。结果表明:海南岛及周围区域 PW整体呈现南湿北干分布,有明显地区差异和季节变化。冬半季南海洋面大气可降水量达50 mm,随纬度增加,向北递减,五指山山区为低值中心,夏半季平均 PW大于冬半季;海南岛8月平均值最大(55.05 mm),年变化为一明显单峰结构。近30 a来,海南岛PW呈总体减少趋势,减少率为0.53 mm·(10 a)-1;夏半季 PW干湿异常年水汽通量存在较明显差异,来自孟加拉湾北部和南海的水汽输送及辐合是造成海南岛夏半季干湿年PW异常的关键因素。

Abstract: Based on the data of NVAP-M and ERA-I reanalysis from 1979 to 2008, the temporal and spatial distributions of rainy-season, dry-season and annual mean precipitable water vapor (PW) were analyzed. The results show that there exist considerably clear regional (southern wet-northern dry), seasonal, and interdecadal changes of PW over Hainan Island. The value of dry-season PW over South China Sea can reach 50 mm. The water vapor amount decreases with the latitude increasing, and the low center of dry-season PW is located in Wuzhi Mountain of Hainan Island. The mean PW in rainy-season over Hainan Island is greater than in dry-season. There is a single peak in annual cycle of monthly mean PW, and the maximum value(53 mm) appears in June. There is also a decreasing tendency about PW with an average decrease of 0.53 mm/10a in recent 30 years. The water vapor fluxes are obviously different between anomalously high PW years and low PW years. Water vapor transport and moisture convergence from the north Bay of Bengal and the South China Sea to Hainan Island is the key factor for rainy-season anomalous PW over Hainan Island in dry and wet years.
