How did the mammalian cloud form a rare meteorological wonder?

Mammatus cloud (mammatus? Clouds), also known as "milky cumulus clouds", are milky white cumulus clouds formed under cumulonimbus clouds. When the cold air in downward flow meets the warm air in the updraft, a pouch-shaped milky cloud is formed. The appearance of mammary clouds often indicates the arrival of storms.

Its strange appearance makes many people think that a big storm or thunderstorm is coming, and the information on some websites also confirms this. But more websites prove that it is usually formed after heavy rain. Whether it's true or not, this bomb-like appearance can't help reminding people whether there are countless terrible unknowns hidden in the clouds and crushing everything on the ground.

Mammatus cloud has a more vivid name, "bumpy cloud", which is a milky cumulonimbus cloud formed under cumulonimbus clouds. It is formed when the cold air in the downdraft meets the warm air in the updraft. It can extend for hundreds of miles in many directions, and each tiled cloud can stay still for 10 to 15 minutes. Beauty comes at a price, and its appearance often indicates that there may be storms or other extreme weather in the future. Many people often mistakenly believe that milky clouds are a precursor to tornadoes or hurricanes. But experts say that the appearance of mammatus clouds often indicates the arrival of storms. When you see this kind of cloud, you often can't help but imagine that maybe a tornado will come in the middle of mammatus cloud and destroy everything.
