Is the winter solstice the coldest in a year?

The solstice in winter is not the coldest time of the year.

The winter solstice, also known as the Winter Festival and the Solstice Festival, is an important solar term in the China lunar calendar and a traditional festival of the Chinese nation. It marks the official start of winter between June 65438+February 2 1 23 in the solar calendar every year. From winter to the sun, the direct point of the sun is located in the tropic of Capricorn, with the shortest day and the longest night in the northern hemisphere. However, the winter solstice is not the coldest time of the year.

After the winter solstice, although the days in the northern hemisphere are getting longer and shorter, the temperature will not rise immediately. This is because the heat absorbed by the earth's surface is still less than the heat lost, so the temperature will continue to drop. In China, the temperature from winter solstice is usually low, especially in the northern region, which can drop to MINUS 10 degrees or even lower. Therefore, the degree of cold in winter solstice is very serious.

However, the winter solstice is not the coldest time of the year. In fact, the coldest time of the year usually occurs after the winter solstice, about December of the lunar calendar. This is because the heat absorbed by the earth's surface is gradually increasing, but the heat lost is still very large, resulting in a continuous decline in temperature. During this period, the temperature in the north can reach a very low value, and even severe cold weather occurs.

Characteristics of winter solstice

China has a vast territory and diverse climate, and the coldest time in different regions is different. For example, in the south, the coldest moment may appear in the twelfth lunar month or the first lunar month, rather than the winter solstice solar term. This is because the climate characteristics in the south are different from those in the north, with high temperature and less cold in winter.

Although the winter solstice is an important solar term in winter, marking the official start of winter, it is not the coldest time of the year. The coldest time of the year usually occurs after the winter solstice, about December of the lunar calendar. The coldest time in different regions is also different, which is related to the change of heat absorption and loss on the earth's surface and the regional climate characteristics.
