Read the weather system somewhere in the northern hemisphere.

Question 1:D

Question 2:C

Test analysis:

Question 1: As can be seen from the figure, when the weather system transits, the wind speed increases rapidly from below 10 to 18 to nearly 40 m/s, far exceeding 10. At 22 o'clock, the wind speed dropped to 0 m/s, and after 2 hours, the wind speed rose sharply to about 40 m/s, and then dropped again. The wind direction is also constantly changing; This is obviously the change of wind speed and direction when the typhoon (hurricane) transits. At 22 o'clock, the wind speed is 0, indicating that the typhoon eye crosses the border. Typhoons (hurricanes) often bring disasters such as strong winds and heavy rains. Option C is correct. Typhoon (hurricane) is generated in the ocean above 10 degrees north latitude, but not in the equatorial region, because the airflow moving along the equator is not affected by the geostrophic deflection force, and the airflow moving horizontally will not form cyclone (typhoon, hurricane) without deflection, so option A is wrong; Option b describes the weather when the cold front crosses the border; Option c describes the weather when the quasi-stationary front crosses the border.

Question 2: As can be seen from the figure, the northwest wind blows first (to the west of the typhoon), and then the southeast wind blows after the typhoon eye crosses the border (to the east of the typhoon), indicating that the typhoon moves from southeast to northwest, and option C is correct.
