After the summer heat, the weather cooled down for a few days.

It didn't turn cold until the end of August after the heat. Every year around July 23rd, the sun reaches longitude 120, marking the beginning of the summer solar term, which is the hottest period and the highest temperature. That is, when the sun runs to the ecliptic; 120 。 Less than 120 can only be considered as the degree of slight heat stroke.

Every year on August 7th or 8th, when the sun reaches 135, it is followed by the beginning of autumn solar term. If the sun has just reached longitude 120, the subtropical high will linger overhead for a long time due to the influence of atmospheric circulation, and the temperature will not drop.

Summer is one of the twenty-four solar terms of the lunar calendar, and the sun is located in the yellow meridian 120. In the hot summer, China people have the custom of drinking tea, drying ginger, burning incense and drinking mutton soup.

The summer solar term is just around the Mid-Autumn Festival in the dog days, which is the hottest period of the year, with the highest temperature and the fastest growth of crops. At the same time, various meteorological disasters such as drought, waterlogging and wind disasters are also the most frequent in many areas.
