It rained when the sun was shining. Why?

As the name implies, solar rain is rain with the sun. There are many reasons for the formation of solar rain, some of which are dark clouds floating in the distance and blown to another place by strong winds; Some clouds with different charges collide with each other under the action of the solar wind, resulting in excessive water vapor content in some areas; Some are formed by the rapid evaporation of water vapor caused by solar radiation; Some are formed by sudden changes in the weather.

Characteristics of solar rain

If the sun is at a low enough angle, solar rain often leads to rainbows. This phenomenon has very similar common names in cultures all over the world, such as fox getting married, tiger getting married, or names related to demons, although there are many different themes? .

Composition: The main component of rainwater is water (chemical formula H2O), and a small amount of sulfur dioxide (chemical formula SO2) and nitrogen dioxide (chemical formula NO2). Usually, the PH value of rain is around 5.6, and rain with a PH value less than 5.6 is acid rain. In thunderstorm weather, rain will contain a small amount of ozone molecules (caused by lightning), as well as various impurities and floating dust in the air.
