What is the meaning of snow in Baoan, Shenzhen?

Shenzhen suffers from freezing due to cold wave

Introduction: Weather Network News This morning (24th), in Fuyong Tangwei Community, Baoan, Shenzhen, I heard the sound of breathing coming from the window. Many people were cheering that it was snowing in Shenzhen! When I walked downstairs, I saw ice particles falling from the sky, hitting the roofs of cars and leaves. A nearby shop owner said that he had never seen snow falling in Shenzhen in the past 20 years. Passing through ice particles like this is a rare occurrence in 20 years. From a meteorological point of view, this is not called snow, but clouds. It is commonly known as snow seeds, snow rice, and snow beans among the people. At 11 pm on January 23, the Shenzhen Meteorological Observatory announced that due to low temperatures and strong winds, as well as the fact that the top of the mountain has been shrouded in rain and fog in recent days, the thatch, branches and even the automatic weather station on the top of the mountain have frozen. A layer of ice shell, but this is not snow, it is a "frozen" phenomenon. This phenomenon is more common in southern mountainous areas in winter, but rare in Shenzhen.

What exactly is "frozen"? It is understood that. This is a meteorological disaster that often occurs in mountainous areas in southern my country. Municipal meteorological experts pointed out that this kind of freezing is not a mysterious phenomenon, but is an atmospheric physical phenomenon. The meteorological explanation is: it continues. In low-temperature and rainy weather, supercooled water droplets (raindrops, fog droplets) in the air collide with the surface of objects near the ground temperature below 0°C and freeze quickly, and gradually form ice with an opaque or translucent layered structure covering the surface of the object. Shell, including smog, rime, mixed smog, etc.
