The beginning of autumn is one of the 24 solar terms. The beginning of autumn will bring changes into autumn, and the weather will slowly cool down. So when will autumn begin in 2018? When is the fall of 2018? Let's take a look.
What's going on tomorrow
Today, the new week begins. The new week will usher in the beginning of autumn in the 24 solar terms. The beginning of autumn is the 13th solar term in the 24 solar terms of the lunar calendar, and also the first solar term in autumn, marking the official start of the season of mengqiu. But in fact, the beginning of autumn was only divided according to the needs of farming when the ancients formulated the 24 solar terms of the lunar calendar. Although it has a word of "autumn", there is still a long distance between the arrival of the beginning of autumn and the arrival of the really cool autumn.
The beginning of autumn is not the beginning of autumn. In the sense of meteorology, autumn is the beginning of autumn. It needs to meet the condition that the daily average temperature is lower than 22 ℃ for five consecutive days. Generally speaking, the beginning of autumn in our city is in the middle and late September, and now it is still in the middle of the dog days, which is still very early.
According to the prediction of the municipal meteorological station, the city will continue to maintain the mode of shower plus high temperature in the new week. The rain will come and go from time to time as a guerrilla. The temperature is about the same as last weekend, and it is expected to be between 25 ℃ and 32 ℃. Severe convective weather in summer often occurs in the afternoon, evening and night, so the rain is still frequent in these periods of the new week, so the people had better take an umbrella with them to avoid being caught by the shower.
What day is the beginning of autumn? What time is 2018
Start of autumn 2018: Tuesday, August 7, 2018 (June 26, 1898 (year of the dog), one day before start of autumn 2018)
It's autumn, but it's not autumn. The division of climate season should be based on the 'average temperature of climate', that is, the local average temperature for five consecutive days is below 22 ℃, which is the real autumn season. China is a vast country with different climates, but at this time most of the regions still do not enter the autumn climate. Moreover, the last day of the hot and rainy days is the third day after the beginning of autumn. Especially in the southern part of China, when the solar term is still summer and summer, the weather season is gradually gone and the temperature is even hotter. Therefore, the period from the beginning of autumn to before the equinox in Chinese medicine is called "long summer".
In fact, according to the standard of climatological division of seasons, the beginning of autumn is when the daily average temperature in the second half of the year drops to below 22 ℃, except that there is no summer area connected with winter and spring and autumn for a long time, few areas in China enter autumn at the beginning of autumn.
The temperature is still high in most parts of China before and after the beginning of autumn. All kinds of crops grow vigorously. Middle rice flowers and seeds, single late round stalks, soybean pods, corn Tassels and silks, cotton bolls, and sweet potato tubers expand rapidly. The demand for water is very urgent. Drought in this period will cause irreparable losses to the final harvest of crops. Therefore, there are three rainfalls in the beginning of autumn, the rice becomes rice, and the autumn rain is drenched, and the land is full of gold
