What is the date in beginning of autumn in 2022?

It's mid-range. Beginning of autumn time in 2022 is August 7th, 2022, the 10th day of the seventh lunar month, and the lodging time in 2022 is July 26th to August 14, so beginning of autumn time in 2022 is 13.

Among the three volts in China, the hottest one is the mid-volt, and there is a folk saying that "the cold is in the March 9th and the heat is in the mid-volt".

Mid-volt, also called second volt, is the hottest period in dog days. This is because the humidity of the surface becomes higher after the lodging, and the surface absorbs more heat every day, but releases less heat, and the surface heat accumulates, so it is getting hotter every day. When entering the alto, the heat accumulated on the ground reaches the highest value, and the weather is the hottest.

In addition, there is much rain in summer, the air humidity is high, and the heat capacity of water is much larger than that of dry air, which is also an important reason for the sultry weather in dog days. The subtropical high intensified in July and August. Under the control of the subtropical high, the descending airflow inside the high makes the weather clear and cloudy, which is beneficial to the sunshine, the ground radiation heats up and the weather is hotter.

Of the three days, the first day and the last day are ten days, and only the middle day is not fixed, which may be ten days or twenty days, and one * * * is forty or thirty days.

Are there dog days after beginning of autumn?

After beginning of autumn is the end. The summer solstice in the third year is the last day, and beginning of autumn in the first year is the last day, that is, the first day after beginning of autumn is the last day, so there is a saying that "beginning of autumn falls behind". There are two situations in the dog days after beginning of autumn. One is that the day in beginning of autumn happened to be Geng Day, so the last autumn happened to be beginning of autumn. This situation is called "autumn"; In another case, the first day of the last autumn is called "beginning of autumn" after the solar terms in beginning of autumn. As the saying goes, autumn is crisp, autumn is crisp.

Weather characteristics after beginning of autumn:

There will be autumn tiger weather after beginning of autumn. Autumn Tiger in China refers to the short-term hot weather after beginning of autumn. It usually happens at the turn of August and September and lasts about 7- 15 days. The reason for the formation of autumn tiger is that the western Pacific subtropical high that controls China gradually moves southward in autumn, but moves northward. Under the control of this high pressure, it turned cloudy and sunny locally, with strong solar radiation and rising temperature. This regenerative weather is called "old woman summer" weather in Europe and "Indian summer" weather in North America.

Due to the vast territory of China, the performance of "Autumn Tiger" is slightly different. For example, the autumn tigers in South China are later than those in the Yangtze River valley, generally delayed by 2-4 solar terms. In addition, the prevention and control time of autumn tigers is long and short every year, ranging from half a month to two months; Sometimes the autumn tiger comes and goes, and then goes back. "Autumn Tiger" weather, although the temperature is high, but generally speaking, the air is dry and sunny, it will not be very hot in the morning and evening, and it will not be too hot to breathe.

Autumn is the transitional season between summer and winter. After autumn in beginning of autumn, the direct sunlight point moved southward from1132 ′ n to 5 57 ′ n. As the direct sunlight point moved southward, the daytime time shortened, the sunshine hours decreased day by day, and the light and heat given to the northern hemisphere also decreased day by day. The weakening of solar radiation gradually reduces the heat available on the ground during the day. But with the extension of the night, the heat radiated from the surface to space increases. As the heat absorbed by the ground is gradually less than the heat lost by the ground, the temperature begins to change from high to low.

Is it cool after beginning of autumn?

No, in terms of solar terms, beginning of autumn refers to the beginning of autumn, but in beginning of autumn, the temperature in some areas is still very high. From the temperature point of view, it will gradually cool down in late September and autumn.

Beginning of autumn has arrived, but not in autumn. The division of climatic seasons should be based on the "average climate temperature", that is, the local average temperature is below 22℃ for five consecutive days, which is the real autumn.

China is a vast country. Although the climate varies from place to place, most areas have not yet entered the autumn climate, and the last days of dog days are still the third day after beginning of autumn.

Especially in the south of China, this solar term is still a hot summer. At the same time, because the typhoon and rainy season are about to pass and the temperature is even hotter, TCM calls the period from beginning of autumn to the autumnal equinox "long summer".

When we arrived in beginning of autumn, the phoenix tree began to shed its leaves, so there is an idiom "Autumn is known by falling leaves". Literally, the word "autumn" consists of "valley" and "fire", indicating the maturity of five grains. Autumn is the transitional season when the weather turns from hot to cold, and then from cold to cold.
