What is freezing rain, how is it formed, and what is the harm?

Freezing rain composed of supercooled water droplets is a weather phenomenon seen in early winter or late winter and early spring. The harm of freezing rain can be divided into two aspects: on the one hand, traffic, on the other hand, agriculture.

1, transportation

A lot of freezing rain will accumulate ice and crush telephone poles, which will not only affect people's normal life and communication, but also affect traffic and travel. Heavy freezing rain will lead to serious road icing, easy skidding of vehicles and high traffic accident rate. In addition, too cold rain will affect the wings and propellers of the aircraft, affect the normal flight of the aircraft, and even lead to aircraft accidents in serious cases.

2. Agriculture

When freezing rain falls on plants, plants will be frostbitten or die, especially some growing seedlings, which are very easy to die in a freezing rain; Larger fruit trees will also be frostbitten, which will affect the yield; Farmland will be frozen, the seedlings to be germinated will be affected, and the best period of soil emergence will be missed, which will affect the normal development of seedlings and cause serious agricultural losses.

The formation of ice rain:

In general, when the temperature of rainwater reaches below freezing point, it will turn into ice and form snow. However, if the temperature of the air layer is high, the ice will return to the liquid state and fall to the ground or objects in the state of cold rain. Such a rainfall process is freezing rain. When freezing rain falls and accumulates too much, it forms the rainy season.

A natural phenomenon that occurs when winter and spring alternate. Spring has come, the cold current has not retreated, it began to rain, and the ground turned into ice. When the local surface temperature is below zero degrees Celsius, the rain turns into ice. After the rain falls, it can't gather together or blend with the ground, but it freezes in a large area.
