When is the dog days of summer in 2020? Is the summer solstice the beginning of the dog days?
Introduction: The start time of the dog days is not fixed every year, and the time of the dog days will also change. So when is the dog days of 2020? Is the summer solstice the beginning of the dog days? Let’s follow the editor of Shuimoxiansheng.com to learn more about it!When does the dog days of summer start in 2020?By querying meteorological data, we know that the dog days of 2020 are from July 16 to August 24.The dog days occur between the Lesser Heat and the End of Heat, and are the hottest, most humid and muggy days of the year. The so-called "fu days" refers to the "three hot days" in the lunar calendar, which is the hottest period of the year. It can be understood in this way: "Fu" means that the weather is too hot, so it is better to stay still and not move. However, the reason why the dog days are called "fu" is because there are many cold factors involved. The three hottest days of the year are the thirty to forty days in the Central Plains. The three hottest days are calculated according to the lunar calendar, and are approximately from mid-to-late July to mid-to-late August in the Gregorian calendar. Is the summer solstice the beginning of the dog days?The summer solstice in 2020 is June 21st; the beginning of the dog days in 2020 is July 16th.Therefore, we can know that the summer solstice has not yet entered the dog days. The third Geng day after the summer solstice belongs to the first dog days. Since the 365 days in a year (366 days in a leap year) are not an integer multiple of 10, a Geng day this year may not be a Geng day next year. That is, the date of Geng day is variable and not fixed, so there are slight differences in the date of the beginning of the dog days every year. Of course, the beginning of the dog days is generally between July 11 and July 21. Then, the fourth Geng day to the fifth Geng day is the middle of the dog days, and the first Geng day to the second Geng day after the beginning of autumn is the last dog days. Each Geng day is 10 days apart, and the number of days in the middle dog days is not fixed. When there are 4 Geng days between the summer solstice and the beginning of autumn, the middle dog days are 10 days. When there are 5 Geng days, the middle dog days are 20 days. The hottest reason in the dog daysAfter the beginning of the dog days, the humidity of the ground becomes higher, and it absorbs more heat every day and emits less heat. The heat on the surface accumulates, so it gets hotter day by day. When the dog days begin, the accumulated heat on the ground reaches its peak, and the weather is the hottest.In addition, there is more rain in summer and the air humidity is high. The heat capacity of water is much greater than that of dry air, which is also an important reason for the hot and humid weather. The subtropical high pressure strengthens in July and August. Under the control of the subtropical high pressure, the downward air flow inside the high pressure makes the weather clear and cloudless, which is conducive to sunlight and ground radiation warming, making the weather even hotter.
