| 摘 要： | 利用云南省123个气象台站1960年以来的降雨量资料,使用年降雨量距平百分率方法,分析楚雄强震与降雨量的关系,结果发现：年降雨量距平百分率≥0.25的台站数大于8,次年云南地区皆有Ms≥6.0地震,也是楚雄地区发生6级强震背景条件；楚雄地区强震前表现涝异常,即该区域强震具有涝—震特征.

| Abstract: | Using precipitation data from 123 stations in Yunnan Province since 1960 and the method of annual precipitation anomaly percentage, we obtain the results.①if there were more than 8 stations with annual precipitation anomaly percentage〉0. 25, earthquakes with M≥6.0 would happen in Yunnan region, which is also the background condition that earthquakes with M≥6.0 would happen in Chuxiong area;② strong earthquakes in Chuxiong area basically happened in the places where stations with annual precipitation anomaly percentage〉 0. 25 comparatively centralized; ③ there were waterlogging abnormity before strong earthquakes in Chuxiong area, that is waterlogging-earthquake character. |
