What month is the Millennium?

White Dew

Dew is water droplets formed by condensation of water vapor on the ground or near-earth objects due to temperature drop. So the Millennium actually indicates that the weather is getting cold. In the climate of 24 solar terms in the basin of our province, the White Dew has the obvious characteristics of rapid temperature drop, the beginning of rain in Mao Mao and the sudden decrease of sunshine, which profoundly reflects the seasonal changes from summer to autumn. The average temperature of the basin in the perennial white dew period is about 3℃ lower than that in summer, and the average temperature in most areas (5 days) has been continuously reduced to below 22℃. According to the standard of dividing four seasons by climatology, the time series begins to enter autumn. Autumn rain in the basin mostly occurs from the white dew to the first frost, with the most in the middle and lower reaches of Minjiang River and Qingyi River, and relatively less in the middle of the basin. The agricultural proverb "There are too many white dew, walking around every day" can't predict the weather by whether it rains on the day of the white dew, but there will always be a period of continuous rainy weather before and after the white dew festival. Moreover, since then, rainfall in the basin has been characterized by low intensity, frequent rainy days and continuous rainfall. Accordingly, the sunshine in the basin during the white dew period is about half that in summer, and the decreasing trend continues until winter. The above-mentioned climatic characteristics of the Millennium season are not conducive to heading and flowering of late rice, but also affect the harvesting and sunning of middle rice, so there is a saying in agricultural proverbs that "the Millennium is sunny and the rice is as white as silver". Only by fully understanding the Millennium climate characteristics and taking corresponding agricultural technical measures can the harm of autumn rain be alleviated or avoided. On the other hand, rainwater should also be used to store water, especially the Bailu in the east of the basin is another solar term with more rainfall after Xiaoman and summer solstice. Don't miss the good opportunity.
