Read the chart of temperature, air pressure, precipitation and wind speed before and after a weather system passes through Shenyang, and complete the question. Question 1: The weather system is ()

Question 1:C

Question 2:B

Test analysis:

Question 1: According to the influence of the weather system, the temperature drops and the air pressure rises, forming an obvious precipitation process, so it is judged that there is a cold front passing by.

Question 2: According to the increase of air pressure and the decrease of temperature, we can know that this weather is a cold front transit, and the turning point of temperature and air pressure is 3 1, so the transit time of this weather system is 3 1. According to the time of precipitation, it can also be judged that the weather system 3 1 arrived in Shenyang. So the answer is option B.
