Read the map of the near-surface weather system in the northern hemisphere (in hectopascals) and answer the following questions. (1) According to the air pressure, ① is the center of _ _ _ _ _ _, ③ is _ _ _ _ _. (1) From the distribution of isobars in the figure, according to the air pressure, ① the ground is the center of high pressure and ③ the ground is the center of low pressure.

(2) (1) The ground is the center of high pressure, and the air sinks vertically. During the sinking process, the air temperature rises, and the water vapor is not easy to condense, so there is plenty of sunshine; (3) The ground is the center of low pressure, and the airflow rises vertically. During the rising process, the air temperature decreases, and the water vapor inside is easy to condense into clouds, causing rainfall.

(3) Specifically, the wind direction is from high pressure to low pressure, and the northern hemisphere deflects to the right. In the picture, the northwest wind blows slowly; The magnitude of wind power depends on the density of isobar, and ② is the most powerful wind power compared with ④.

So the answer is:

(1) high pressure and low pressure

(2) sunny days? cloudy and drizzly for days on end

(2) Northwest? ② ② The isobars are dense and the horizontal pressure gradient force is large.
