What is the difference between the weather system viewed from the air pressure distribution and the weather system viewed from the air flow movement?

(1) According to the data in the figure, judge the name of the weather system. Figure A is a low-pressure system because its air pressure center is low and its surroundings are high. Figure B shows a high-pressure system and an anticyclone system, because its pressure center is high and its surroundings are low.

(2) The cyclone is of low pressure, and the airflow direction is counterclockwise convergence in the northern hemisphere (clockwise convergence in the southern hemisphere). The anticyclone is high pressure, and the airflow direction is clockwise divergence and sinking in the northern hemisphere (counterclockwise divergence and sinking in the southern hemisphere). A is located in the northern hemisphere and B is located in the southern hemisphere, so B is the southeast wind and C is the northeast wind.

(3) Generally, the wind power is judged according to the density of isobars. The density of isobars in this picture is the same, so the magnitude of wind force is compared by comparing the pressure gradient difference. In the figure, the pressure gradient (force) at A is greater than that at C, so the wind force at A is greater.

(4) There is a lot of water vapor in the air, and rainy weather may occur in area A. Because the center of area A is low pressure, the prevailing airflow rises and the temperature drops, resulting in rainy weather.

(5) B is high pressure, prevailing downward flow and sunny day. In winter, B is controlled by high pressure, the airflow sinks, and the weather is cold and dry.

So the answer is:

(1) low-pressure anticyclone

(2) Drawing:

(3) the pressure gradient (force) at a is greater than that at c.

(4) Rainy weather in Area A, due to the rising airflow and the lowering of temperature, rainy weather is formed.

(5) In winter, there may be cold, dry and sunny weather in Area B (there may also be strong winds or even cold waves. )
