| 摘 要： | 利用江西周边11个探空站资料与江西省内84个站1959—2007年降水资料,根据天气学原理和数理统计学方法,对江西省大气中总水汽量、总云水量、水汽交换次数、水汽更新率、实际总降水量等进行计算分析。结果表明:总水汽量、总云水量最大值均出现在6月(1975年),最小值出现在12月(1963年);中度干旱频率区域总云水量值最大,轻度干旱频率区域总云水量值最小;水汽交换次数平均为7.23次/月;水汽更新率平均4.22天/次;总水汽量、总云水量的地理分布呈北部高、南部低趋势分布;总水汽量、总云水量、总降水量相关性比较好,年变化呈现多峰型。

| Abstract: | Using the radiosonde data from 11 meteorological stations and precipitation data from 84 meteorological stations over Jiangxi Province from 1959 to 2007, according to the synoptic meteorological principles, computation and analysis are conducted with the mathematical statistic method on the total water vapor, total cloud water, the number of water vapor exchanges, water vapor turnover rate, actual total precipitation, etc. The results indicate that the maximum value of total water vapor and total cloud water appeared in June （in 1975）, the minimum value appeared in December （in 1963）; maximum total cloud water was found in the area with moderate drought frequency, and minimum total cloud water in the area with low drought frequency. The number of water vapor exchanges was averagely 7.23 times per each month, and the water vapor turnover rate was averagely 4.22 days for each time. The correlations between total precipitation and total water vapor, total cloud water are good, and the annual variation exhibited a multi-peak pattern. The geographic distribution of the total water vapor and total cloud water shows a tendency of high in the north and low in the south. |
