The weather system somewhere in the northern hemisphere

Question 1:D

Question 2:C

Question 3: A.

Question 1: According to the diagram, the air pressure at C is greater than 1020, and the south wind blows at B; A high latitude, controlled by cold air mass; The isobar in area B is sparse, the horizontal pressure gradient force is small and the wind force is weak. So choose option d in this question.

Problem 2: The junction of cold and warm air masses near the front is prone to inversion. From the cold air mass to the high altitude, it is easy to cross the front, causing inversion. In Figures A and D, there may be an inversion near the front controlled by the cold air mass, so choose option C in this question.

Question 3: According to the figure, the distance moves 2cm when moving 8 hours 120km, and the point A will be located on the west side of the high pressure center C, and the wind direction will change to southwest wind, and the isobar will become sparse and the wind speed will weaken. So choose option a in this question.
