Meteorological changes in summer solstice

After the summer solstice, although the direct point of the sun began to move south from the Tropic of Cancer, the days in the northern hemisphere began to shorten gradually, but the temperature will continue to rise for a while, because the heat radiated by the sun to the ground is still more than the heat radiated from the ground to the air, so there is a saying that the summer solstice is not too hot. As the saying goes, "it's a hot day in dog days", and the real hot day is from mid-July to mid-August on the Gregorian calendar.

From summer to the sun, the sun directly reaches the northernmost part of the year, and the daylight time in all parts of the northern hemisphere reaches the longest in the year. During this period, the temperature in most parts of China was high, the sunshine was sufficient, the crops grew rapidly, and the physiological and ecological water demand was high.

After the summer solstice, the ground is heated strongly and the air convection is strong, and thunderstorms are often easy to form in the afternoon to evening. This kind of hot thunderstorm comes and goes, and the rainfall range is small. People call it "dividing fields in summer and rain".
