What's the difference between solstice summer and long summer?

First of all, the difference between long summer and summer solstice: the time span and the angle of the sun are different.

1, Long Summer is the seventh solar term among the 24 solar terms of the lunar calendar, and the first solar term in summer indicates the official start of the Xia Meng season. When the sun reaches 45 degrees of the yellow meridian, it is a long summer solar term. The bucket refers to the southeast, and the dimension is long in summer. Everything has grown to this day, hence the name Long Summer. Long summer comes on May 5th or 6th every year.

2. The 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 day of summer solstice, the sun moves to 90 degrees of the yellow meridian (summer solstice, currently in Gemini), and the position where the sun directly hits the ground reaches the northernmost point of the year, almost directly to the Tropic of Cancer. At this time, the daylight hours in all parts of the northern hemisphere reach the longest in the whole year.

Second, the difference between long summer and summer solstice: the climate characteristics are different.

Before and after 1 and "Long Summer", only the area south of Fuzhou-Nanling line in China is the real summer of "hiding trees and reflecting ponds", while some parts of northeast and northwest have just entered spring, and the average temperature in most parts of the country is around 18 ~ 20℃. After the long summer, Jiangnan officially entered the rainy season, and the rainfall and rainy days increased significantly. Continuous rainy days not only caused wet damage to crops. Before and after the long summer, the temperature in North China and Northwest China rose rapidly, but the precipitation was still not much. In addition, the wind is strong and evaporation is strong in spring. Atmospheric dryness and soil drought often seriously affect the normal growth of crops.

2. After the summer solstice, the ground is heated strongly and the air convection is strong. Thundershowers usually form in the afternoon to evening. This kind of hot thunderstorm comes and goes, and the rainfall range is small. In most cases, during the "summer solstice" period, the middle and lower reaches of the Yangtze River and the Jianghuai basin are rainy and frequently rainstorm, which is prone to floods. Summer solstice season is the "Meiyu" season in Jianghuai area. At this time, it is the ripe period of plums in Jiangnan, and the air is very humid. Cold and warm air masses meet here, forming a trough of low pressure, leading to rainy weather.

Summer solstice is one of the 24 solar terms, which occurs on June 2 1 or 22 of the Gregorian calendar every year.

Third, the difference between long summer and summer solstice: customs and dietary characteristics are different.

1, among the people, people drink cold drinks to cool off in summer. In summer, there is a custom of boiling tender broad beans in Jiangnan water town. In some places, there is also the custom of calling people in summer. According to folklore, eating eggs in the long summer depends on the heart. Because eggs are shaped like a heart, people think that eating eggs can keep the spirit from losing money. It will be a hot summer after a long summer. In order not to lose weight in hot summer, Chang Xia should take supplements. There is a custom of weighing people after lunch in the long summer. People hang a big wooden scale at the entrance of the village or platform, and a stool is hung on the scale hook. Everyone takes turns to sit on the stool and weigh people. When weighing flowers, the caller said auspicious words. The old man will say, "weigh 87 and live to 91."

2. "Wheat Zongzi" and "Summer solstice cake": Jiangnan food customs generally include wheat Zongzi, corn millet, plums, wonton and noodle soup. "Wujiang County Records": "On the summer solstice, make wheat dumplings." . After the first sacrifice, you pay for it. Not only eat "wheat dumplings", but also give them to each other as gifts. On the day of summer solstice, farmers will roll pancakes, bake them, add vegetables, pods, tofu and bacon, eat them after ancestor worship, commonly known as "summer solstice cakes" or give them to relatives and friends.

Winter Solstice Wonton, Summer Solstice Noodle: China has a saying since ancient times that "winter Solstice Wonton, summer Solstice Noodle". In Jiangnan, eating noodles is an important custom in many areas. There is a saying that "eating noodles on the solstice in summer shortens the day". There are many kinds of noodles in the south, such as Yangchun noodles, dried soup noodles, shredded pork noodles, three fresh noodles, sesame oil noodles and cold noodles, while noodles with gravy and noodles with dregs in the north. "Because new wheat has appeared from summer to day, eating noodles from summer to day also means tasting new things."
