What is the snow in July?

If the cold and warm air conflict violently, it will produce heavy rainfall; However, if the airflow suddenly pulls the low-level cumulonimbus clouds containing ice crystals or snowflakes to the ground, there will be a spectacle of snowflakes flying in a small area in a short time.

Meteorologists say that such weather should be the result of cold and warm convection. Cumulonimbus clouds are not large, and the zero layers of clouds are not distributed at the same level. Part of it will be concave to the ground, and these clouds contain snowflakes and hail. In the hot summer, the cold and warm air convection is intense, and the sudden strong wind pulls the low-altitude cumulonimbus clouds containing snowflakes and hail blocks to the ground quickly. Because the local temperature is too low, in some areas, there will be a short-term snowflake flying in the hot summer.

"Seven In the snow" is usually in hot summer, and the zero layer of the atmosphere is generally three or four kilometers above the ground. Snowflakes, hail, unstable supercooled water, etc. Can only appear on the zero floor. Hail is often seen in summer, because it is not easy to melt, and it is rare for snowflakes to fall from the sky without melting.
