as the saying goes, & lsquo; & rsquo; cold in September, hot in three volts'. It can be seen that the dog days are the hottest time of the year. With the silent departure of June 2018, people began to get nervous. So, when will the dog days start in 2018? How long will the dog days last this year? Now let's get to know
How many days is the 2018 three volt day? How long is the 2018 three volt day
Dog days
How many days is the three volt in 2018
The starting and ending time of the three dog days in 2018 is July 17, 2018 and August 25, 2018, totaling 40 days. The specific initial, intermediate and final voltage times are as follows:
The first 10 days in 2018: July 17, 2018 to July 26, 2018; the second 20 days in 2018: July 27, 2018 to August 15, 2018;. Last 10 days in 2018: August 16-25, 2018.
As the saying goes, "the heat is in three volts", especially in the city, it seems to be in a huge steamer. After falling into the ground, the surface humidity becomes larger, more heat is absorbed every day, less heat is emitted, and the heat of the surface layer accumulates, so it gets hotter day by day, entering into the third volt, the accumulated heat of the ground area reaches the highest peak, and the weather is the hottest. In addition, there is more rain in summer, and the air humidity is large. The heat capacity of water is much larger than that of dry air, which is also an important reason for the sultry weather. In July and August, the subtropical high was strengthened. Under the control of the subtropical high, the downdraft inside the high pressure made the weather clear and cloudless, which was conducive to the sunshine, the ground radiation increased temperature, and the weather was even hotter. Therefore, the climate characteristics of "three dog days" are high temperature, low air pressure, high humidity and low wind speed. At this time, the feeling of human body is naturally sultry.
How long is it not hot after three volts
Generally speaking, going out means going out on a rainy day, and the heat gradually fades away; and the solar term of summer heat means the end of summer heat, and the weather should be cooler and cooler. However, in some areas of the south, people who have just experienced a little bit of autumn are often at the end of summer heat, and feel the hot weather again, that is, the legendary autumn tiger.
The reason for the formation of the autumn tiger is that the subtropical high in the Western Pacific Ocean, which controls China, gradually moves southward in autumn, but then moves northward. Under the control of the high, there are clear clouds, strong solar radiation and rising temperature. Because of China's vast territory, the performance of "autumn tiger" is slightly different. For example, the autumn tiger in South China comes later than that in the Yangtze River Basin, generally delaying 2-4 seasons.
In addition, the control time of the autumn tiger varies from half a month to two months every year; sometimes the autumn Tiger comes, goes and looks back. Gu Tieqing, the author of Jialu in the Qing Dynasty, said: 'after the summer heat, the weather is pleasant, and it will be cold for another 18 days. 'it means about 18 days of sweating. But although the temperature of autumn tiger is high, the air is dry and sunny in general. It's not very hot sooner or later, so it won't be too hot to breathe.
