Hey, what’s the weather like? It’s sunny over there and it’s raining over here.

Sun Rain.

How come it sometimes rains when there is a clear sky? The rain at this time is called "solar rain". In fact, when it rains, it still rains. There are clouds. Some solar rain is caused by dark clouds in the distance producing rain, which is blown to another place by strong winds. Some are caused by a sudden change in the weather and it starts to rain. The rain falling from high altitudes has disappeared before it hits the ground. So although the weather seems sunny, it starts to rain.

This is caused by the collision of two high-altitude particles with different charges under the action of the solar wind, resulting in excessive water vapor content in the air in local areas. , and due to solar radiation, water vapor evaporates quickly. The rain falling from high altitudes has disappeared before it hits the ground, so although the weather looks sunny, it is raining.
