Lead: There is a ballad about the twenty-four solar terms. The specific content is: "Spring rains shake the spring and clear the valley days, and summer is full and summer is hot." Autumn dew, autumn frost, little snow in winter and cold in winter. The two festivals remain unchanged every month, with a maximum difference of one or two days.

So, among the 24 solar terms, which are the hottest and which are the coldest? Come and have a look with me.

The hottest and coldest of the 24 solar terms.

The hottest of the 24 solar terms is the Great Summer. Great summer heat, the last solar term in summer. Combat refers to c; The solar calendar is120; July 22-24 of Gregorian calendar. "Summer heat" is heat, and summer heat is extremely hot. Summer heat is relatively mild and hot, and it is the clearest and hottest solar term in a year, and "damp-heat steaming" reaches its peak at this time. Climatic characteristics of summer: high temperature and scorching heat, frequent thunderstorms and typhoons.

The summer solar term is the hottest time of the year, just before and after the "midsection" of the "dog days". In summer, the sun is like fire, the temperature is high, the humidity is high, and there is much rain. Although it is inevitable to suffer from high temperature and humidity, it is very beneficial to the growth of crops, and crops grow fastest during this period.

The coldest of the 24 solar terms is the Great Cold. The Great Cold is the last of the 24 solar terms. Fighting refers to ugliness; The solar meridian reaches 300; Celebrate on the calendar of 65438+1October 20-2 1 every year. Great cold, like slight cold, is also a solar term indicating the cold weather. Great cold refers to extremely cold weather. According to China's long-term meteorological records, there is no slight cold in the great cold solar terms in the northern region; But for most parts of the south, the coldest is the great cold solar term.

Great cold solar terms

There is a folk saying that "a slight cold is the most important thing, and it is cold without wind." Great cold refers to extremely cold weather. Although the winter solstice solar terms are the lowest in the northern hemisphere, the coldest time in a year is the slight cold and severe cold solar terms after the winter solstice solar terms, especially the severe cold solar terms; This is because after the winter solstice, the direct point of sunlight will gradually move northward, but in the following time, the direct point of sunlight will always be in the southern hemisphere, and the heat in the northern hemisphere will always be lost, and the heat absorbed during the day is still less than the heat released at night. Therefore, after the winter solstice, the temperature in the northern hemisphere will continue to decrease, with the lowest temperature during the severe cold solar term, which is the coldest solar term in a year.

Because China has a vast territory and a large span between the north and the south, the climate between the north and the south is quite different. According to China's long-term meteorological records, there is no slight cold in the great cold solar terms in the northern region; But for most parts of the south, April and September are the coldest, so the big cold solar terms are colder than the small ones. Slight cold and severe cold are the periods with the least rainfall in a year. During the annual cold solar term, the rainfall in South China is only 5 to 10 mm. ..
