Read the Diagram of Temperature, Barometric Pressure, Precipitation and Wind Speed Changes before and after a Weather System Passing through Shijiazhuang City, and complete the question 17- 18 1: About the Weather System.

Question 1:C

Question 2:B

Question 1: This question examines common weather systems and weather. The weather system produces precipitation after crossing the border, and the expected value decreases after crossing the border, which should be cold front weather; The precipitation time is 3 1, so the weather system arrives in Shijiazhuang on 3 1. The wind speed first increases and then decreases. So this question chooses option C.

Problem 2: After the cold front crosses the border, the temperature drops, the number of cold patients increases sharply, the road surface freezes, traffic accidents occur frequently, and pests and diseases decrease, which is beneficial to crop growth in the coming year.
