Summer Solstice

Summer Solstice is the 10th solar term among the twenty-four solar terms. Dou refers to Wu; the sun's ecliptic longitude is 90°; the festival is on June 21st to 22nd in the Gregorian calendar. On the summer solstice, the sun reaches its northernmost point of the year, almost directly hitting the Tropic of Cancer. At this time, the daylight hours in various places in the northern hemisphere reach the longest of the year. For the Tropic of Cancer and areas north of it, the summer solstice is also the day of the year when the sun is at its highest at noon.

The summer solstice is the turning point of the sun's northward journey. After the summer solstice, the direct point of the sun begins to move southward from the Tropic of Cancer, and the days in the northern hemisphere begin to gradually become shorter. For areas of China located north of the Tropic of Cancer, the height of the noon sun begins to decrease day by day after the summer solstice; for areas of China located south of the Tropic of Cancer, the height of the noon sun returns south after the summer solstice, and only begins to decrease day by day when the sun shines directly again. .

High temperatures, high humidity, and thunderstorms from time to time are the characteristics of the weather after the summer solstice. The summer solstice is in the position of mid-summer, that is, the noon position, and noon belongs to Yang. Although the summer solstice has stronger yang energy and the longest day, it is not necessarily the hottest day of the year, so the heat close to the surface is still accumulating at this time, and When the maximum is not reached.

The Summer Solstice is not only one of the twenty-four solar terms, but also one of the folk festivals of the "Four Seasons and Eight Festivals" in ancient times. Since ancient times, people have had the custom of worshiping gods and ancestors at the Summer Solstice. In addition, after the summer solstice, people generally consume refreshing soup, herbal tea, sour plum soup, etc. to escape the heat.

Characteristics of the Summer Solstice solar term

1. Plum rain season. The summer solstice is the "plum rain" season in the Jianghuai area. This is the ripening period for plums in the south of the Yangtze River. The air is very humid. Cold and warm air masses meet here and form a low-pressure trough, resulting in continuous rainy weather.

2. Heavy rain. In most cases, the "summer solstice" coincides with the plum rains in the middle and lower reaches of the Yangtze River and the Yangtze-Huaihe River Basin. Heavy rains frequently occur, which can easily cause floods and even threaten people's lives and property. Attention should be paid to strengthening flood prevention work.

3. Convective weather. After the summer solstice, the ground is heated intensely and air convection is strong. Thunderstorms are often formed from afternoon to evening. This kind of hot thunderstorm comes and goes quickly, and the rainfall range is small. People call it "summer rain across Tiankan". The heavy rainfall caused by convective weather is not as beautiful as described in the poem, and often brings local disasters.
