Nature in the Great Cold Solar Term

The natural phenomena of severe cold change as follows:

With the arrival of the great cold solar terms, natural phenomena have changed obviously. First, the temperature dropped significantly. The temperature in severe cold solar terms is generally below-10 degrees, and sometimes even lower.

Secondly, the weather in severe cold and solar terms is generally sunny, but the air humidity is very high, and the water vapor in the air will form tiny ice crystals, making the temperature in the air lower. In addition, the sunshine time in the severe cold solar terms is also obviously reduced, generally only a few hours, while the night time is obviously increased, sometimes even lasting until the early morning.

The severe cold solar term is the last of the 24 solar terms on December 23rd of the lunar calendar every year, and it is also the coldest day of the year. The arrival of the great cold solar terms marks the arrival of winter and the end of the year.

The arrival of the great cold solar terms will also affect the animals and plants in nature. Animals will change their activity rhythm according to the change of temperature. For example, birds will migrate to warm places, while mammals will make their hair thicker to resist cold weather.

Plants will also change their growth rhythm according to the change of temperature. For example, trees will put their roots deep into the soil to resist cold weather, while plants will shrink their leaves to reduce water loss.
