Weather circulation

(1) Subtropical high pressure area (2 points)? Westerly belt (2 points)

②A(2 points)? Northwest wind (2 points)

(3) High in Asia (or Mongolia) (2 points)? Cold and dry (2 points)

Analysis of test questions: (1) Pressure area A is located near 30, so it is judged as subtropical high pressure area; B is located in the mid-latitude, so it is judged as the mid-latitude westerly belt. (2) The equatorial low pressure area and subtropical high pressure area in the figure are both south, so it is judged as winter in the northern hemisphere, and the Eurasian continent in the right figure is controlled by the high pressure center, so it is judged as winter; Figure B The Eurasian continent is controlled by the low pressure center, and it is judged as summer. The northwest monsoon prevails in winter in East Asia. (3) controlling Eurasia as Asian high in winter; Most parts of China are affected by the northwest monsoon, and the weather is cold and rainy.

Comments: This question is relatively difficult. It is the key to master the distribution and movement law of the global pressure belt and the difference between winter and summer monsoon in East Asia. Pay attention to comparative analysis. This topic can also be designed in combination with the influence of the difference in thermal properties between land and sea on the distribution of global pressure zones.
