What are the characteristics of solar terms in beginning of autumn?

The beginning of the autumn solar term is among the 20 solar terms, representing the beginning of summer and autumn. At present, the climate is still relatively hot, and entering the autumn climate is also a gradual process. Therefore, beginning of autumn season, heatstroke prevention and cooling work can not be relaxed. So what are the characteristics of solar terms in beginning of autumn? Let's use the old calendar to have a look!

Climatic characteristics of beginning of autumn

From this day on, autumn began, and autumn was crisp. Since then, the temperature has gradually decreased from the hottest time.

Beginning of autumn has arrived, but not in autumn. The division of climatic seasons should be based on the "average climate temperature", that is, the local average temperature is below 22℃ for five consecutive days, which is the real autumn. China is a vast country. Although the climate varies from place to place, most areas have not yet entered the autumn climate, and the last days of dog days are still the third day after beginning of autumn. Especially in the south of China, this solar term is still a hot summer. At the same time, because the typhoon and rainy season are about to pass and the temperature is even hotter, TCM calls the period from beginning of autumn to the autumnal equinox "long summer".

The earliest areas are in Qiu Lai, Heilongjiang and northern Xinjiang, and will also fall in mid-August. In general, the autumn wind in the capital Beijing will be cooler in early September, and the autumn around Qinhuai begins in mid-September. The autumn wind will blow to Lishui, Zhejiang, Nanchang, Jiangxi and Hengyang, Hunan 165438+ 10 in early June, and the news of autumn will reach Leizhou Peninsula, and the footsteps of autumn will reach the "ends of the earth".

The intersection of autumn begins, the direction of astronomical changes.

The day when it was handed over to beginning of autumn was July of the lunar calendar, which was also called "Shen Yue Day". In beginning of autumn, the sun is at the declination of+16 19', which is much more southerly than the +23 26' in summer solstice, so the daytime in Beijing is shortened to 14 hours and 04 minutes (15 hours in summer solstice). The weather is still very hot. After beginning of autumn, there are still "crouching" and "autumn tigers" still exist. So we should pay attention to heatstroke prevention. However, a leopard cannot change his spots. There is a "beautiful day" when it is hot at noon and cool in the morning and evening, and "one autumn rain is cold and ten autumn rains are frost."
