| 摘 要： | 利用南昌、赣州2个探空站1988～1997年7～9月07：00与19：00探空资料和江西省85个气象台站1988～1997年7～9月降雨量资料，对降水效率进行计算和分析，结果表明，江西省历年(1988～1997)季降水效率为7．65％，7、8、9月各为7．04％、9．90％、6．02％，降水效率最大值为1377％，最小值为3．55％。低压辐合类天气影响时降水效率最大，季平均值为20．48％，其它依次是低槽、台风低压、大陆高压、东风波影响时降水效率也比较大，季平均值各为11．90％、8．56％、7．05％、7．04％，台风外围影响时降水效率最小为3．33％。 |

| Abstract: | Usual radiosonde data (1988 to 1997,07:00,19:00) and surface precipitation data (1988 to 1997) are used, and the natural precipitation efficiency in summer in Jiangxi is calculated and analyzed. The results indicate that the average precipitation efficiency in summer is 7.65% in the period of 1988 to 1997, 7.04%, 9.90%, 6.02% in July, August, September in Jiangxi Province, respectively. The maximum precipitation efficiency is 13.77%. The minimum precipitation efficiency is 3.55%. Under the influence of the weather of low-pressure convergent systems, the precipitation efficiency is the greatest (20.48%) and under the influence of the weather of typhoon low systems, the precipitation efficiency is the least (3.33%). The precipitation efficiencies are 11.90%, 8.56%, 7.05%, 7.04% under the weather systems of low-though, typhoon low pressure, continental high pressure, easterly wave, respectively. |
