Read the weather in the northern hemisphere

(1) high pressure and low pressure? (4 points)

(2) sunny days? Rainy day? (4 points)

(2) northwest (north) ② ② Isobars are dense, and the horizontal pressure gradient force is large (6 points)

Test analysis: (1) Reading the distribution of isobar values, we can know that ① the ground is the center of high pressure and ③ the ground is the center of low pressure.

(2) (1) The surface airflow sinks to form fine weather; (3) The ground airflow rises, resulting in rainy weather.

(3) When reading the map, the distribution of isobar (②) should be that the wind direction changes from high pressure to low pressure and from right to northwest; Compared with the density of isobars in the two places, the isobars are dense and the horizontal pressure gradient force is large, so the wind is strong.
