This topic examines the common weather systems and the comprehensive analysis ability of pictures. (1) The dashed arrow in the figure is perpendicular to the isobar, pointing from high pressure to low pressure, so it is judged as a horizontal pressure gradient force. On the basis of the horizontal pressure gradient force, the solid arrow is inclined to the right in the northern hemisphere and intersects the isobar, so it is judged as the horizontal airflow direction. (2) According to the air pressure distribution, the air pressure in the center of Figure A is higher than that in the surrounding area, so it is judged as a high-pressure center, and the air pressure in the center of Figure B is lower than that in the surrounding area, so it is judged as a low-pressure center. From the point of airflow movement, A indicates that the airflow flows from the center to the periphery, so it is judged as an anticyclone; The airflow in Figure B flows from the periphery to the center, so it is judged as a cyclone. (3) In the control area shown in Figure A, the airflow sinks, so the weather is fine.
