Is sleet snow?

No, sleet and snow are special precipitation phenomena.

Sleet refers to a special precipitation phenomenon formed by rainwater mixed with partially melted snow and falling at the same time. Snow and sleet are both meteorological phenomena, both belong to precipitation, and are weather phenomena under low temperature conditions, but they have the following differences: 1. The physical properties and physical forms of the precipitation water are different; 2. Weather (Temperature) conditions are different; 3. Meteorological properties are different.

The special condensation phenomenon of sleet and snow has temperature requirements. It mainly occurs when the temperature of the part of the atmosphere closest to the ground is slightly higher than the freezing point of water (0℃ or 32_). For the low-level warm air below the freezing altitude, in order to melt the snow falling from the high clouds into rain, the thickness of the warm air layer will vary between 230m and 460m, and this change is caused by the mass of the snowflakes. Produced by the vertical temperature gradient with the melting layer of the atmosphere. When the thickness of the melt layer atmosphere enters this range, rain and partially melted snow will naturally mix together, forming sleet as it falls to the ground.
