cause

The special condensation phenomenon of sleet requires temperature, which mainly occurs when the temperature of the part closest to the ground is slightly higher than the freezing point of water (0℃ or 32℉). For low-level warm air below freezing point, the air layer thickness of warm air will vary from 230 meters to 460 meters, so as to deepen the snow falling from high clouds into rain.

This change is caused by the mass of snowflakes and the vertical temperature gradient of the melting layer atmosphere. When the thickness of dissolved layer atmosphere enters this range, rain and partially melted snow will naturally mix together and fall to the ground to form sleet.

For low-level warm air, its temperature gradient will affect the thickness of melting layer. When the temperature gradient is large, the height of melting layer required for snow melting will be small during snowfall, and vice versa.
