| 摘要: |
| 本文利用1961～2014年贵州省76个气象台站的逐日降水资料对贵州省秋季绵雨的总体特征和分月特征进行分析。研究表明：全省年均秋绵雨次数最大值区域位于贵州省西部和中部高海拔地区一带，贵州秋季绵雨次数具有自西北向东部或向南部递减的分布规律。9～11月各月秋绵雨天数最大值区域均位于贵州省西部一带，但其分布规律不尽相同，从变化趋势来看，9～11月各月秋季绵雨次数距平百分率变化的倾向率均呈不同程度的减少趋势。 |

| Abstract: |
| Based on the daily precipitation data of 76 meteorological stations in Guizhou Province from 1961 to 2014, the general characteristics and monthly characteristics of autumn continuous rain in Guizhou Province are analyzed. The results show that the maximum annual average autumn sponge rain frequency is located in the western and central high altitude areas of Guizhou Province, and the autumn sponge rain frequency in Guizhou has a decreasing distribution pattern from northwest to east or south. The maximum number of autumn rainy days in September to November is located in the western part of Guizhou Province, but the distribution law is different. From the change trend, the trend of the percentage change of the number of autumn rainy days in September to November is decreasing in varying degrees. |
