Due to the change of cold air, the weather is sunny and hot during the day, but the temperature drops rapidly after the evening.

The temperature difference between day and night is gradually widening. During the white dew, the summer monsoon is gradually replaced by the winter monsoon, and the cold air changes from defense to attack. In addition, when the direct point of the sun moves south, the sunshine time in the northern hemisphere becomes shorter, the light intensity weakens, and the ground radiation dissipates heat quickly, so the cooling speed gradually accelerates. The Millennium basically ended the sweltering heat in summer, and the weather gradually turned cold, and the cold gave birth to dew condensation.

The ancients used four seasons with five elements. Autumn belongs to gold, gold and white alternate with each other, and autumn dew is described in white, hence the name "White Dew".
