It rains when it is sunny. Why?

We often encounter rain in our daily life. Usually, when it rains, dark clouds are gathering. But there is also a very special situation, that is, it rains heavily on sunny days, and sometimes it can even rain for a long time. This sunny and rainy situation is what we call it? Sun rain? , is a relatively rare weather condition. So why are there sunny days and rainy days? In fact, this is all caused by the rapid change of cumulonimbus clouds in the sky.

? Sun rain? The conditions for formation need clear skies.

When the weather is good, the local weather is sunny. There may not even be many clouds in the sky at first, but the whole earth only has sunshine. To form the so-called solar rain, such a clear sky is essential. Cumulonimbus clouds or two clouds with different charges are slowly approaching in the distance.

Cumulonimbus clouds or two clouds with different charges come into play.

At this time, those unusual clouds in the distance began to appear and play a role. Some solar rain is caused by dark clouds in the distance and is blown to the sunny side 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 the air in some areas and rapid evaporation of water vapor by solar radiation.

Another possibility is that the weather suddenly changed and it began to rain. But before the rain falls in the sky, the clouds have been blown away or disappeared, and the sky has begun to clear up. This situation may also cause the formation of solar rain.

Compared with normal rainfall, the duration of solar rain is short and the rainfall is small.

Compared with normal rainfall, "solar rain" takes a short time to form and ends quickly. What did this lead to? Sun rain? In terms of rainfall, there is very little, and the time of solar rain is relatively short, which is determined by the unique characteristics of solar rain. As a relatively rare rainfall pattern, solar rain? It can be regarded as a very immature rainfall process, and it is normal for rainfall time and less rainfall.

So we don't need to be so surprised whether it was sunny or rainy that day. This is just a rare normal weather process, which can't represent anything or explain anything. And the old saying in China that it's sunny and rainy, plant yellow seedlings and eat white rice. ? It refers to the sun rain, which is considered as a good omen for a good harvest when sowing seedlings. Maybe it's just the beautiful expectation of a bumper harvest in the hearts of our working people!
