A Method or Formula for Memorizing the Map of Pressure Zone and Wind Zone

(1) Determine their names according to ABC's positioning. A is near the equator, which is the equatorial low pressure area. AB is the trade wind zone in the northern hemisphere, and the wind direction is the northeast wind. BC is between 30 and 60 degrees, which is a westerly belt, and the wind direction in the northern hemisphere is southwest wind. (2) Solve the problem according to the distribution law of climate types. Tropical desert climate, distributed in the west coast of the mainland at 20-30 degrees. Distributed at 25-35 degrees on the east coast of the mainland. (3) Under the control of the general high-pressure belt, the downward airflow is popular, the temperature becomes higher, and it is not easy to condense, resulting in less rainy weather. Under the control of the low pressure zone, the updraft prevails, the temperature drops and the water vapor condenses, which is easy to form rainy weather. A is near the equator, where updraft prevails, temperature drops, water vapor condenses and precipitation is more. B is controlled by subtropical high. Not easy to condense, less precipitation. So the answers are: (1) equatorial low pressure area, northeast trade wind area and westerly wind area (2) tropical desert climate, and subtropical monsoon climate (3)A is controlled by equatorial low pressure area, where updraft prevails and precipitation is more.
