Michelle Si Nuo?

Michelle (meteorological term): the phenomenon of solid precipitation in weather phenomena. It is composed of white opaque oblate ice particles with a diameter less than 1 mm, and does not rebound when falling on hard ground.

In the relatively stable and relatively low temperature gas layer, there are Leng Yun drops or fog drops whose temperature is lower than zero degrees Celsius but not frozen. In the process of falling ice crystals at high altitude, Leng Yun drops or fog drops are encountered, which are frozen and fused into rice snow. (explore the reason? )

The meteorological conditions for the formation of rice snow require small disturbance and relatively low temperature, which generally comes from stratus clouds with low height, and sometimes rice snow can form in dense fog and fall to the ground. Generally, the precipitation formed in the process of a rice snow precipitation is not large.
