Question 1:D?
Question 2:C
Test analysis:
Question 1: Look at the materials. It was mid-winter weather, which means it was winter. It snowed all day, probably over the horse's knee, indicating a snowstorm. Blizzard weather in winter is affected by cold front activity, and D is right. Figure A shows the center of low pressure, which is active. In winter, there is basically no cyclone activity in China's monsoon climate zone. A is wrong. In winter, China is mainly engaged in cold front activities, while warm front activities will not be snowstorm weather. B is wrong. Figure C shows the high pressure center, and there will be no snowfall. C is wrong.
Question 2: Combined with the previous analysis, this weather system is a cold front activity. After the cold front crossed the border, it was controlled by a cold air mass. Under the influence of a single cold air mass, the air pressure is high, the temperature is low and the weather is fine. C is right. Both a and b are wrong. Only controlled by the cold air mass, the pressure difference per unit distance is small, the horizontal pressure gradient force is small, the wind force is small, and D is wrong.
