Tarim weather forecast

(1) Block A is located in the center of high pressure, controlled by high pressure, and the downward flow prevails. During the sinking process, the airflow is not easy to condense, and the weather is fine.

(2) The dotted line A is located in the ridge of high pressure, so it is impossible to form a front, while B and C are located in the trough of low pressure. In the horizontal direction of the cyclone in the northern hemisphere, the airflow flows counterclockwise from the periphery to the center, and C is easy to form a cold front near B and C; B is a warm front, then the temperature rises, the air pressure drops and the weather improves.

(3) Wind power depends on the density of isobars. The denser the isobar, the stronger the wind. In the place in the picture, ② has the largest wind speed.

(4) The eastern and northeastern parts of Inner Mongolia Plateau are affected by the atmospheric pressure center, with rainy weather, easterly winds blowing in Tarim Basin and southerly winds prevailing in North China Plain, so it is selected as: A. 。

So the answer is:

(1) high pressure? Sunny and dry

(2)b The temperature drops, the air pressure rises and the rain clears up.

(3)②② Isobars are dense and the pressure gradient force is large.

(4) Answer
