What does the solar term white dew mean? Brief introduction of Millennium.

1, the white dew indicates that the weather is getting cold. Millennium is an important festival reflecting the temperature changes in nature, basically ending the sultry summer, and it is a turning point from sultry to cool in autumn.

2. After entering the Millennium solar terms, the summer monsoon is gradually replaced by the winter monsoon, and the cold air goes south in batches, which often brings a certain range of cooling.

3. In the first two solar terms in autumn, beginning of autumn and the summer heat are still very hot, because the heat brought by the sun has not diminished. The so-called "heat is in dog days", which appears between midsummer and hot summer, and it is the highest temperature and muggy day of the year. The reason for the high humidity in dog days is that the southeast wind blows in dog days, and the southeast direction is the Pacific Ocean and the Indian Ocean, so the air is humid, and the humidity of the wind causes the high humidity in dog days. After late autumn, the opposite is true. The northwest wind blows and the northwest inland is dry. The dry northwest wind leads to a dry climate after late autumn. After entering the Millennium solar terms, the summer monsoon is gradually replaced by the winter monsoon, and the cold air goes south in batches, which often brings a certain range of cooling. The folk proverb "Autumn night in the white dew, a cool night" describes the situation that the temperature drops rapidly.

The first two solar terms in autumn are sultry. Autumn is generally cool, until after the Millennium solar terms, it gradually tends to be cool and dry since the Millennium solar terms. In late autumn, the climate turns from hot to cold, and everything comes into being with cold and gradually falls. This is the season of alternating hot and cold. The most obvious change in autumn is that the leaves of vegetation change from lush green to yellow, and the leaves begin to fall and the crops begin to mature.
