What season is cold dew? Is cold dew the beginning of winter?

Introduction: Many solar terms have four seasons. You can tell which season they belong to at a glance, but there are still some solar terms whose meanings are so vague that you really can't tell which season just by looking at their names. So, what season is the cold dew? Is cold dew the beginning of winter? Want to know whether the cold dew belongs to autumn or winter, just look at my introduction.

What season is cold dew?

Cold dew is autumn. The time of cold dew is about June 8th or 9th every year, 10, after beginning of autumn and before beginning of winter, so the cold dew belongs to autumn, and the first frost comes after the cold dew.

Cold dew is the seventeenth of the twenty-four solar terms and belongs to the fifth solar term in autumn. The twenty-four solar terms say: "In September, the dew is cold and will condense." It means that after the cold dew, the temperature becomes lower than usual, and the dew on the ground is colder and will soon condense into frost. So after the cold dew, pay attention to keep warm and wear more clothes. Generally, the temperature is warmer during the day, the weather is sunny and the autumn is crisp, which is especially suitable for going out with friends, but at night, the temperature will drop sharply. At this time, many people get sick because of catching cold.

Generally, after the cold dew, it seldom rains because of the influence of climate change. Only a few special places may rain, such as Yunnan, Sichuan and Guizhou, and some places have begun to snow, such as Northeast China and Xinjiang. Cold dew is also a transition from cold to cold, telling everyone that winter is coming and it is time to start preparing!

Is cold dew the beginning of winter?

Cold dew is not the beginning of winter, but it is a symbol of winter and a transitional period from cool to cold. After the cold dew, the dew increases and the temperature decreases. In the cold dew season, Nanling and the vast area to the north have entered autumn, and the northeast and northwest regions have entered or are about to enter winter.

At this time, it is already late autumn in the north, with white clouds and red leaves and occasional early frost. In the south, autumn is getting stronger and cicadas are dying. The cold dew solar term begins at the end of the first ten days of 10 and ends at the end of 10. The direct point of the sun continued to move southward in the southern hemisphere, and the angle of sunlight in the northern hemisphere began to tilt obviously. The solar heat received by the ground is obviously less than that in summer, and the influence of cold air can sometimes extend to South China.

What is the temperature of the cold dew solar term?

Cold dew solar term is the solar term of temperature drop. At this time, people have been able to feel the chill obviously, so everyone began to seek warmth in dressing. The cold dew will drop quickly these days.

The sudden drop in temperature is a feature of the cold dew solar terms. After the autumn wind and autumn rain brought by a strong cold air, it is not uncommon for the temperature to drop by about eight degrees and ten degrees.

The cold dew is in Gregorian calendar 10 month, and the regional difference of the national average temperature distribution is obvious. The average temperature in most parts of South China is above 22℃, and it is even higher in Hainan, which is above 25℃, and it has not yet come out of summer.

Jianghuai and Jiangnan are generally between 15℃ and 20℃, and the southeast, North China and Huanghuai are between 16℃. At this time, the average temperature in the northwest and parts of the north-central part of the northeast has reached below 8℃. The average temperature in some plateau areas of Qinghai Province is even lower than 0℃.

Analysis on cold dew temperature

The cold dew temperature in South China is less than 20℃; When the temperature along the river does not exceed 30℃, the maximum toxicity drops below 10℃. After the cold dew in the northwest plateau, it is generally lower than 10℃, and the temperature in most parts of South China continues to drop. The average daily temperature in South China is less than 20℃. Even in the areas along the Yangtze River, it is difficult for the temperature to rise above 30℃, while the minimum temperature can drop below 10℃.

Due to global warming, the cooling date may be postponed. Except for a few valley lowlands, the five-day average temperature in the northwest plateau is generally lower than 10℃. According to the standard of dividing the four seasons by climatology, it is already winter, and first frost is thousands of miles away, which is quite different from the autumn colors in the south.
