What is the weather sign of freezing rain?

Freezing rain: It is a disastrous weather in early winter or late winter and early spring. It is composed of ice-water mixture and freezes immediately after colliding with objects with a temperature below 0℃.

Freezing rain hazard

1, expressway traffic is blocked by ground icing, and traffic accidents also increase. If the ground freezes, it will freeze the green winter wheat or the crops planted in early spring. In addition, freezing rain will also destroy young forests and frostbitten fruit trees in a large area.

2. A lot of freezing rain will crush power lines and telephone lines, and severe freezing rain will make houses collapse. When an airplane flies in a cloud with supercooled water droplets, the wings and propellers will accumulate water, which will affect the aerodynamic performance of the airplane and cause a crash.

Extended data:

The condensate of freezing rain is called "Song Yu", which is a glass-like transparent or dim ice sheet with rough surface formed when supercooled precipitation hits the surface of an object with a temperature equal to or lower than zero degrees Celsius.

Song Yu is harder, more transparent and denser than other forms of ice particles (0.85g/cm3), while Wusong, which is similar to Song Yu, has a density of only 0.25g/cm3. The rain song has a clear structure and a smooth surface, commonly known as "tree hanging" or ice tree condensation. In southern China, freezing rain is called "the next ice", "the sky" or "cowhide".

In the wettest season, warm spring and autumn prevail in the northern part of winter. For example, the wettest month at Tianchi weather station in Changbai Mountain is May, with an average of 5.7 days, followed by September, with an average of 3.5 days. Due to the low temperature, there is no rainy season in winter from February to March in 65438.
