Slight summer is the 1 1 solar term among the 24 solar terms in China. The time of light summer is July 7th or 8th every year, and it is light summer when the sun reaches the longitude of the Yellow River105. Therefore, this year's light summer is July 7.
Summer heat, which means hot, is a small heat, not very hot. Slight summer heat is relative to great summer heat. The ancients thought that it was not the hottest time of the year, so it was called slight summer heat. Slight summer heat means that the weather is getting hot, but it is not the hottest yet.
Judging from the climate of light summer, the probability of rain on this day is relatively high. There is a proverb related to the solar terms of the summer heat: "Rain hits the head of the summer heat, and cows are not needed for 45 days." This sentence means that if it rains three days after the arrival of the summer heat, it will not stop for the next 45 days.
The rainy weather is much more special. Because of the continuous rainfall, the farmland is extremely muddy, and the cattle can't work in the fields. However, because the weather is hot before and after the solar terms, it is better for farmland to rain.
Meteorological changes:
The sunshine time in the northern hemisphere is gradually shortened in the summer, but why is the temperature still rising in most parts of China? This is because the direct point of the sun is moving south, but it still shines directly in the northern hemisphere, and the heat in the northern hemisphere is still more than its branches, so the temperature will continue to rise during this period.
The average temperature in southern China is about 26℃ during the light summer. In mid-July, the average daily temperature is higher than 30℃ and the maximum daily temperature is higher than 35℃ in the low-altitude valley area of southeast China. In the northern part of the northwest plateau, frost and snow can still be seen at this time, which is equivalent to the scene in early spring in South China.
