Wu Shengyu explained on Facebook that the cell-shaped cloud street of cold air represents the trajectory of northeasterly wind intensifying southward. However, the cold air is still too weak this season, the actual cooling range is limited, and it needs the blessing of radiative cooling, which lacks the blessing of radiative cooling. , the low temperature in various places this morning is relatively higher than yesterday.

Wu Shengyu reminded that today and tomorrow (20-21 days) will be affected by the strengthening of the northeasterly wind. The northern and eastern half of the windward side will have more cloud cover, and there is a chance of local short-lived showers.
