What will happen to nature in the first frost season?

The first frost temperature drops, the sunshine shortens, the water vapor condenses, and the plants shed leaves.

The first frost is one of the traditional 24 solar terms in China, and it is celebrated every year from 23rd to 24th in Gregorian calendar 10/kloc-0. This solar term marks the end of autumn and the beginning of winter. In the first frost season, a series of changes will occur in nature, including temperature drop, shortened sunshine time, water vapor condensation, defoliation and so on. Let's take a closer look at these changes.

First of all, the temperature drop is one of the most obvious changes in the first frost season. With the decrease of the direct angle of the sun, the solar radiation energy received by the ground decreases correspondingly, resulting in a gradual decrease in temperature. During the first frost, the temperature is usually pleasant during the day, but it will drop obviously in the morning and evening, and sometimes even frost will appear.

Secondly, the first frost season is also one of the shortest sunshine seasons in a year. As the direct point of the sun moves south, the sunshine time in the northern hemisphere is gradually shortened. This leads to shorter days and longer nights. This change will have a certain impact on the growth and development of animals and plants.

In addition, the first frost season is an important period for water vapor condensation. As the temperature drops, the water vapor in the air will start to condense into water droplets or ice crystals, forming fog or dew. In the morning or at night, these water droplets or crystals will form frost flowers or ice crystals, making the surrounding environment very beautiful. But at the same time, we need to pay attention to prevent traffic safety hazards caused by road icing.

Finally, the first frost season is also the time when plants shed their leaves. With the decrease of temperature and the shortening of sunshine time, plants gradually enter dormancy period. In order to reduce energy consumption, plants will shed leaves to protect themselves. The branches of plants will become clearer after falling leaves, which also adds a unique landscape to winter.

In a word, the first frost season is one of the most remarkable periods of natural change. The phenomena such as temperature drop, shortened sunshine time, water vapor condensation and plant defoliation all appear in order to adapt to the environment and maintain ecological balance. These changes also indicate that winter is coming, and we need to make corresponding preparations to cope with the coming cold weather.
