潮汐对局地性降雨的作用

The Effect of the Coasted Local Rain on the Tide

根据调研资料，运用大气物理学原理从宏观和微观两个角度，初步分析了夏季期间潮汐的变化对华南沿海局地降雨形成的影响。发现遇到涨潮时，海上积云移到沿海陆地上空容易造成局地性降雨，即在开始降雨前几小时通常是高潮位。

The effect of the tide variation during summer on the formation of coastal local rain in South China has been analysed preliminarily from the macro and micro angles on the basis of research dare and atmospheric physics. When the flood tide occurs, cumulus moves toward the land and the local rain happens easily. In other words, the high tide level appears usually several hours before it begins to rain.
