As shown in the figure, the distribution of main pressure fields in the northern hemisphere in January and July is superimposed. Read the picture and answer the questions. Question 1: the distribution

As shown in the figure, the distribution of main pressure fields in the northern hemisphere in January and July is superimposed. Read the picture and answer the questions. Question 1: the distribution law of the pressure field shown in the picture is a. January question 1:C?

Question 2:B

Question 3:D

This question examines the distribution of barometric centers.

Question 1: Due to the difference of thermal properties between land and sea in the northern hemisphere, the Asian high formed on the Eurasian continent in January, which cut off the sub-polar low belt, leaving the low in the ocean and forming the Aleutian low in the Pacific Ocean; Iceland low formed in the Atlantic Ocean; In July, the Asian depression formed on the Eurasian continent, which cut off the subtropical high zone, leaving the high in the ocean and forming the Hawaiian high in the Pacific Ocean. Azores high formed in the Atlantic Ocean; Therefore, item C is correct.

item 2: item a is cold and dry if it is affected by cold and high pressure in winter; Therefore, item a is wrong. The east coast of the B-E compressor field is the west coast of North America, with a Mediterranean climate and hot and dry summer; Correct; The western continental coast of Ding compressor field is the east coast of North America, with subtropical monsoon climate and hot and rainy summer. Correct. So choose item B.

Question 3: Item A is Asian high, and the near-surface airflow is divergent; Mistake. Item b indicates the Asian low pressure, which is formed due to the thermal action; Mistake. The weather system of item C is Aleutian low pressure, which is stronger in winter; Mistake. Item D and E, the weather system is Hawaiian high, which is powerful in summer, correct.
