The picture below is a "simple picture of surface weather in a certain area at a certain time." Read the picture and answer the following questions. Small question 1: The wind direction at M in the picture is A. Northeast B. Southeast C

Small question 1: C?

Small question 2: D

Test question analysis: < /p>

Quiz 1: First, draw a vertical line of the isobars through point M, and mark the direction of the pressure gradient force from high pressure to low pressure. In the northern hemisphere, affected by the geostrophic deflection force, the air flow deflects to the right. You can It is directly judged that the wind at M should be northwest, and C should be selected.

Quick question 2: Find the low pressure center in the picture, draw the low pressure trough line, and judge that the air flow around the low pressure is counterclockwise. It can be seen that the cold air in the north pushes the front to move towards the warm air in the south, and the front moves towards the warm air in the south. The precipitation is mainly after that, so it is a cold front weather process, so D should be selected.
