origin

Millennium is one of the 24 solar terms of the lunar calendar. When the sun reaches 165 degrees, it is called the Millennium solar term. Millennium is the third solar term in autumn, marking the end of Qiu Meng and the beginning of Mid-Autumn Festival. 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. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. The temperature difference between day and night can reach more than ten degrees. Yang Qi reached its peak in the summer solstice, and these two extremes must be reversed, and Yin Qi also rose at this time. When it comes to the White Dew, the yin gradually increases, and the morning dew gradually thickens and condenses into a layer of white water drops, so it is called the White Dew. As the saying goes:? 18 basin heat, never exposed for a thousand years. ? These two sentences mean that it is still hot in summer, so you must take a bath with a basin of water every day. After eighteen days, in the new millennium, don't be shirtless and naked, lest you catch cold. There is another saying:? The Millennium is charming, and the autumn equinox is beautiful. ? This means that if there is dew before and after the white dew, the late rice will have a good harvest.

? White deer? This is a festival that reflects the temperature changes in nature. Lou, is it? White deer? Unique natural phenomena after solar terms. The weather at this time, as the Book of Rites says:? The cool wind and dew are chilling. ? According to the 24 solar terms, right? White deer? Interpretation of moisture condensation of soil and water into dew, autumn belongs to gold, golden white, white dew color, and gas begins to cold? . The ancients also said in Xiao Weijing:? Is the fifteenth day after summer the Millennium? Yin Qi is getting heavier and the dew is condensed and white. ? In fact, meteorology shows that at this time of the solar term, the weather becomes cool and the sun is still very hot during the day. However, as soon as the sun returned to the mountains, the temperature dropped rapidly. At night, the water vapor in the air condenses into tiny water droplets, which are very densely attached to the green stems, leaves or petals of flowers and trees, showing white color. Especially after being exposed to the morning sun, it looks more crystal clear and flawless, which is really attractive. White deer? Good name.

Climatic characteristics

After plants began to have dew entering the Bailu solar term, summer monsoon was gradually replaced by winter wind, cold air turned to attack, and warm air gradually retreated. Cold air going south in batches will often bring a certain range of cooling. People love to use it? White dew autumn night, one night cool one night? Proverbs are used to describe the situation that the temperature drops rapidly.

At this time, the precipitation in northern China is obviously reduced, and the autumn is crisp and dry. During this period, the first autumn rain in the middle and lower reaches of the Yangtze River can often alleviate the previous water shortage. However, if the cold air meets a typhoon, or the cold and warm air are evenly matched, the two sides are in a dilemma, and heavy rain or low temperature and continuous rain are not good for the growth of autumn crops. Continuous rainy weather often occurs in the eastern part of Southwest China, South China and West China. There may be heavy rain caused by tropical weather system (typhoon) in the southeast coast, especially in the south China coast. In addition, autumn drought, forest fire and first frost may also occur in some areas at this time. If the summer droughts in the middle and lower reaches of the Yangtze River, West China and South China are not nourished by autumn rain, summer and autumn droughts may all form. There is a proverb that describes: There is no drought in spring, and the drought in autumn is halved. Building houses in spring drought and grain shortage in autumn drought. ? In some northern areas, such as Shaanxi, Shanxi, Gansu, North China and other places in the northwest, autumn precipitation is inherently less. If severe autumn drought occurs, it will not only affect the harvest of autumn crops, but also delay the sowing and emergence growth of autumn sowing crops and affect the harvest of the following year. In addition, with the autumn drought, especially the dry air and the increasing wind in mountainous forest areas, the forest fire risk in autumn began to enter a period of high incidence.

On August 15, the wild goose gate opened and the wild goose wore frost? . Frost is caused by the invasion of cold air. The daily average temperature is above 0℃, and the surface temperature drops below 0℃. The water between crop cells freezes, constantly absorbing the water in the cells, leading to cell dehydration and crop withering or death. Sometimes, although there is no frost on the surface of plants, crops will still be frozen because the surface temperature is below 0℃. This phenomenon is called black frost and it is also a kind of frost.
