Which is the hottest dog in dog days

The highest degree of three volt days is the middle volt, followed by the first volt and the last volt. Three volt days are hot because the surface humidity increases, and the heat absorbed every day can not be fully dissipated. And during this period, the subtropical high strengthened, making the sky less cloudy and allowing the sun to shine more directly on the ground.

Many people know that between July and August every year, we will enter dog days, which means that this period of time is the hottest time of the year. But in fact, there is a difference in the temperature of each volt in three volt days.

Three volt days can be divided into first volt, middle volt and last volt, of which the highest temperature is middle volt, followed by first volt and last volt. There is a folk saying called 'cold in Sanjiu, hot in Zhongfu'. From this sentence, we can also see that Zhongfu is the hottest day in Sanfu.

The reason why it is so hot in the dog days is that the humidity on the ground increases during this period. It will absorb a lot of heat every day, but it can't be emitted. And during this time, the subtropical high strengthens, making the sky less cloudy, which will make the sun shine more directly on the ground.
