近40年云南省平均总微雨量占年总雨量比例、年平均总微雨日占年总雨日比例均呈下降趋势，并有从北向南逐渐减少的分布规律；近40年云南省年平均能见度也呈下降趋势，其趋势分布同微雨降水趋势分布比较一致；微雨降水的变化同干燥晴天能见度存在正的相关关系，其中云南省东部地区相关显著；而温度与微雨降水存在负相关；云南省气溶胶在一定程度上抑制微雨降水，云南东部气溶胶对微雨的影响比较显著。
近40年雲南省平均總微雨量佔年總雨量比例、年平均總微雨日佔年總雨日比例均呈下降趨勢，併有從北嚮南逐漸減少的分佈規律；近40年雲南省年平均能見度也呈下降趨勢，其趨勢分佈同微雨降水趨勢分佈比較一緻；微雨降水的變化同榦燥晴天能見度存在正的相關關繫，其中雲南省東部地區相關顯著；而溫度與微雨降水存在負相關；雲南省氣溶膠在一定程度上抑製微雨降水，雲南東部氣溶膠對微雨的影響比較顯著。

The total average annual of the trace of precipition in accounted for the proportion of the total annual rainfall and The total average annual date of the trace of precipition in accounted for the proportion of the total an- nual rainfull date all have decreased in nearly 40 years. Moreover, the regularity of distribution shows that the quantity has decreased from north to south. The visibility has also decreased, and The trends of distribution is more consistent with the distribution of the trace of precipitation. There was a positive correlation between the change of the trace of precipitation and the visibility of sunny day, particularly in the east of Yunnan. However, there was a negative correlation between the trace of precipitation and the temperature. The Aerosol restrain the Trace of Precipitation to some extent, also particularly in the east of Yunnan.
