The following figure shows the distribution map of the near-surface weather system in an area (unit: hectopascals). Read the map and answer the following questions. (10) (1)D is affected by air pressure.

(1) high; Sunny; rise

(2)D； The weather is clear, the atmospheric weakening effect is weak during the day, the temperature is high, the atmospheric reverse radiation is weak at night, and the temperature is low.

(3) cold; Temperature drop?

(4) North/Northwest; e； The isobars at point E are denser.

This topic examines weather charts.

The central air pressure at (1)D is higher than its surroundings, and it is a high pressure center. Downstream is dominated by high pressure control, so the weather is fine; C is the low pressure center, so the updraft is dominant;

(2)D is controlled by high pressure, so the weather is clear and the daily temperature difference is large;

(3) The chart shows that the cold front is about to move to place A, so place A is about to experience the cold front weather process and the temperature will drop.

(4) The direction at E can be distributed by isobar. Considering that the horizontal pressure gradient force is perpendicular to isobar, from high pressure to low pressure, the northern hemisphere leans to the right, thus forming northwest wind. When the isobar at E is dense, the horizontal pressure gradient force is large, so the wind force is large.
