A common situation is that there is a small-scale cumulonimbus cloud next to a place, or at the edge of the cumulonimbus cloud, the cloud is on one side and the sun is on the other. Raindrops falling in the clouds meet the wind in mid-air, fall obliquely at a certain angle, and fall to the area where the sun shines, forming solar rain.
Cumulonimbus clouds? The king of clouds? , is the most in the cloud family? Is it tall? When clouds and cumulonimbus clouds appear, they are often accompanied by lightning, and sometimes even severe weather phenomena such as hail, short-term strong winds and tornadoes appear.
One of the characteristics of cumulonimbus clouds is that a single shadow can only bring rain! Thunderstorms in summer are brought by cumulonimbus clouds. If several cumulonimbus clouds in an area gradually develop and merge together, a wide range of short-term thunderstorm weather may occur in this area; However, if only a few cumulonimbus clouds are mature in an area, it may be raining where these clouds float, but the place that cumulonimbus clouds do not affect is the situation where the sun shuttles through the clouds.
Another situation is that the small-scale weather system in the air changes rapidly, and the short and rapid updraft may lead to sudden cloud rainfall in a small area.
After a short rain, the updraft weakened and the clouds quickly disappeared. Because water drops will encounter air resistance in the process of falling, it takes some time to fall. When the rain falls, the clouds have dissipated, and then there will be solar rain.
Solar rain is common in midsummer season, and the atmosphere is full of energy and unstable, which is easy to trigger this special weather phenomenon on a small space-time scale.
Finally, this kind of weather is more common in the south, especially in summer in the south, where there is often sun rain, and then you can see rainbows.
