What is the beginning of the solar term? What month is it in dog days?
The crouching time in the dog days begins with the solar term from summer to Sunday. The traditional almanac stipulates: "Three Geng accounting lies on the summer solstice day", which means "counting down from the summer solstice day until the third Geng day". Geng day refers to the day with "Geng day" as the prefix in the main branch calendar.
In addition, the length of stay is not fixed every year, depending on the length of stay. If the accommodation is 10 days, the dog days are 30 days. If the time of middling is 20 days, the time of three volts is 40 days.
What month is the dog days? In 2022, the dog days are from July to August. The specific time is as follows:
Initial period: July 2022 16-July 25, 2022, *** 10 day.
Zhongfu: July 26-August 2022 14, ***20 days.
Terminal: August 5, 2022-August 24, 2022, *** 10.
Which is the hottest in the front, middle and back?
The dog days are divided into three periods: the beginning, the middle and the end, in which the middle is the hottest and the middle time is the longest. After the dog days, the humidity of the ground becomes higher, and the ground absorbs more heat every day, but emits less heat, so the heat on the ground accumulates day by day. When entering the alto, the accumulated heat on the ground reaches the highest value and the weather reaches the hottest time.
The midsummer in 2022 starts from July 26th and lasts for ***20 days. The first day and the whole day are 10 and 10 respectively, so the dog days in 2022 are 40 days.
Whether it is hot before lodging or hot after lodging.
After entering the volt, the surface temperature will rise, resulting in an increase in daily heat absorption, while the heat emitted is decreasing, and the surface heat will accumulate, so it is getting hotter every day. Generally, after entering the volt, the accumulated heat on the ground will reach the peak, 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 greater than that of dry air, which is also an important reason for the sultry weather. 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 sunshine, the ground radiation heats up and the weather will be hotter.
