Isn't it hot when you come out?

It will get cold after the dog days, and it will be a little cooler. It's very hot in dog days. After dog days, the weather will gradually get cold. Although the temperature is still high during the day, it will gradually get cold in the morning and evening. Pay attention to adding clothes in the morning and evening to prevent colds. However, there will be an autumn tiger after the dog days, mainly because the subtropical high in the western Pacific gradually moves south and lifts north, resulting in an increase in temperature. However, whether and when autumn tigers will appear in different regions are different.

The first lodging is the first lodging of "three volts". Its date is from the third Geng day to the day before the fourth Geng day. Because every Geng day is 10 days apart and the initial lodging time is 10 days, the word "V" in the dog days has two meanings. First, it means that Yin Qi was forced by Yang Qi to hide underground; Second, it means that the weather is too hot to lie still, and its climate feature is "high temperature and high humidity".

Initial lodging mechanism

"V" means being forced to hide underground. There are three kinds of fu: initial fu, middle fu and final fu, and their dates are determined by the solar terms and dates of the dry branch calendar. According to China's traditional calculation method, the third and fourth Geng days from summer to the future are the first (head) and middle start dates respectively, and the first Geng day after beginning of autumn is the last first day.

Because every Geng day is 10 day apart, the stipulated time of the first and last days is 10 day, and because the third Geng day (the first day) after the summer solstice solar term appears in the morning and evening, the duration of the intermediate days is short, which leads to high humidity in the dog days. The reason is that the southeast wind blows in dog days, while the southeast is the ocean, and the air is humid. The humidity of sea breeze causes dog days.
