What is the time after the heat?

After the summer heat, the time series came to early autumn. According to the astronomical almanac of China, the "beginning of autumn" solar term was ushered in at 2 1: 00 on August 7th, Beijing time, and the last summer ended, and the cool wind gradually came. With the arrival of beginning of autumn, the whole autumn began gradually. Beginning of autumn marks the beginning of autumn in the annual periodic law. "The sky is full of summer colors and the leaves are moving in autumn." When you arrive in beginning of autumn, the phoenix tree will definitely begin to shed its leaves, which is why there is an idiom "One leaf falls to know the autumn in the world".

Beginning of autumn is the 13th solar term in a year and the first solar term in autumn. Although the date is calculated in this way, in meteorology, people will take the average daily temperature below 22 degrees Celsius for five consecutive days as the symbol of beginning of autumn. According to this standard, in fact, few areas in China can really fall on that day in beginning of autumn. Like the Jianghuai area, it may have to wait until September. As the saying goes, "an autumn rain brings a cold." After beginning of autumn, the heat and dryness in summer will gradually disappear, the temperature difference between day and night will gradually increase, and the cool wind will blow. This process will continue until the official arrival of autumn.
