What's the change in the weather from summer solstice to Sunday?

Summer solstice is one of the 24 solar terms, which occurs on June 2 1 or 22 of the Gregorian calendar every year. On the solstice in summer, the direct sunlight on the ground reaches the northernmost point of the year and almost directly reaches the Tropic of Cancer. At this time, the day in the northern hemisphere is the longest, and the farther north it is, the longer it is.

June 26th or 22nd is the summer solstice. On the day of summer solstice, the sun directly reaches the northernmost point of the year, almost directly to the Tropic of Cancer (23 26' 28 "44 north latitude), and the daytime in the northern hemisphere is the longest, and the farther north it is, the longer it is. It is the longest day in a year in the northern hemisphere, and it takes about fourteen hours from sunrise to sunset in the south of China. Although the summer solstice has the longest day and the highest sun angle, it is not the hottest time of the year. Because, close to the surface of the heat, at this time still continue to save, did not reach the maximum time. As the saying goes, "Hot days are in dog days", and the real hot weather is calculated by summer solstice and beginning of autumn. From mid-July to mid-August, the temperature is the highest in all parts of the country, and the highest temperature in some areas can reach about 40℃. After the summer solstice, the temperature will continue to rise for some time, and about twenty or thirty days is the hottest weather. From summer to the future, the southern part of China is often controlled by subtropical high, resulting in summer drought. The rainfall in the western part of South China has obviously increased, which has gradually changed the rainfall distribution situation in South China from more in the east to less in the east since spring. If there is a summer drought, it is generally expected to be lifted at this time. In the past 30 years, the number of large-scale floods in western South China in late June was small, but the degree was serious. Therefore, special attention should be paid to preparing for flood control. The summer solstice solar term is the solar term with the largest annual rainfall in eastern South China. In order to enhance drought resistance and win a bumper harvest in agriculture, it is an important measure to catch the rain in front of these areas.
