Meteorological changes during the Bailu solar term

Bailu is the watershed between heat and coolness, and "Bailu" represents the end of the summer heat.

In addition, the position of the sun directly shining on the ground moves southward, the sunshine time in the northern hemisphere becomes shorter, the sunshine intensity weakens, and the night is often clear and cloudless. The ground radiates heat quickly, so the temperature drops gradually. There is a saying that "Bailu and autumnal equinox nights are cooler every night."
