/kloc-around 0/0, the front crosses the border.

Rain and snow weather; After the cold front, the temperature dropped, the air pressure increased and the weather turned fine.

(3)

The sudden drop in temperature is not good for the elderly and infants, and it is easy to catch a cold and pneumonia. Cold front transit pressure changes greatly, which is easy to cause
