Questio
Question 1:A
Question 2: D.
Question 1: This question examines the formation of wind. The horizontal movement of the atmosphere is called wind, and the direct cause of wind is the horizontal pressure gradient force, which is perpendicular to the isobar and points to the low pressure. At high altitude, the wind direction is only affected by the horizontal pressure gradient force and geostrophic deflection force, and the wind direction is finally parallel to the isobar; Near the ground, the wind direction is also affected by friction, and the wind direction finally intersects the isobar. So the northeast wind is blowing at ① in the picture. So choose option a in this question.
Question 2: A place is controlled by an anticyclone, and the weather is fine; ② The ground is affected by cold front, and there may be cold wave weather; The second place is cyclone, and the airflow rises vertically, which is easy to form rainy weather; ② Low latitude, located at one side of the heating mass, with high temperature and low air pressure. So choose option d in this question.
