What does the summer solstice solar term mean?

The summer solstice solar term means that hot summer is coming. Summer solstice is one of the 24 solar terms, which occurs on June 2 1 or 22 of the Gregorian calendar every year.

During the summer solstice, the temperature is high, the sunshine is sufficient, the crops grow rapidly, and the physiological and ecological water demand is high in most parts of China. At this time, the precipitation has a great influence on agricultural output, and there is a saying that "raindrops are worth tens of millions in summer solstice".

The summer solstice is not only an important solar term, but also one of the oldest festivals in China. There is a view that the Dragon Boat Festival in traditional festivals originated from the solstice festival in summer.

Meteorological changes:

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.
