Question 1: According to the weather conditions of materials, it should be judged that a cold front passed by. After the cold front passes, the area will be controlled by the cold air mass, so the temperature will drop, the air pressure will rise and the weather will turn fine.

Question 2: The disastrous weather caused by cold front includes heavy rain in summer, cold wave in winter, freezing injury in spring and sandstorm in northern China.
