The first question is correct.

Question 2: The day length at point C is 12 hours, and the period is 12 hours (because the morning and dusk lines coincide with the meridians, indicating that the sun is directly hitting the equator).

Question 3: 10 o'clock local time at point B (6 o'clock in the morning line and 6 o'clock in the morning line are 60 degrees away, 15 degrees for one hour) Beijing time cannot be calculated because I don't know which meridian is.

Question 4: Changshu China's northern hemisphere day length and short night represents the beginning of summer A is the vernal equinox, corresponding to Ding, the direct point of the sun moves northward from the equator.

Question 5: The sun directly hits the Tropic of Cancer, and on the summer solstice, the height of the sun at noon decreases from the Tropic of Cancer to the north and south.

Question 6: The height of the sun at noon = 90 degrees - the difference in latitude.

The sun directly hits the north latitude at 0 degrees a of the equator, and the latitude difference is 23 degrees 26 minutes, so the height of the sun at noon is 90-23 degrees 26 minutes = 66 degrees 34 minutes.

1）b>a>d>c

4) Vernal equinox Ding.

5) From the Tropic of Cancer to the north and south, the northern loop and the area north of it reach the maximum value of the year, and the minimum value of the year in the southern hemisphere.

1) BADC (2) 12, 24 (3) 10 o'clock, 18 o'clock (4) vernal equinox, D (5) The solar elevation angle decreases from the Tropic of Cancer to the north and south sides at noon. (6) 66 degrees 34 minutes.

7:b (you'll know this picture when you understand it).

8:b (Taiwan just passed the Tropic of Cancer, and the subtropical high at this time spread to both sides with Taiwan as the center, that is, when the sun is near the equator, the sun moves northward, the pressure belt moves north, the sun moves south, and the pressure belt moves south).

7. The warm and humid airflow is the southeast monsoon from the subtropical high. It is wrong to draw easterly and northerly winds in the picture. 8、b

7. b The direction of the warm and humid airflow should be southeast wind, and the subtropical high in 8 and b 6 July generally occurs south of the Yangtze River, so B should be chosen

b The high-pressure airflow rotates clockwise to converge, e.g. southeasterly wind should prevail in the southb

The correct answer to this question should be item C, because at this time there is low pressure on land m, and at the same latitude at sea it should be the period of subtropical high strength. Item B is wrong on the cause of the formation of high pressure three--- the formation of the subtropical high should be caused by aerodynamic subsidence.

Ask the student to review and memorize the knowledge of the thermal circulation part.

Or imagine for yourself, high pressure divergence, low pressure convergence--- then in the eastern sea air from the center of pressure to the surroundings, so in the vertical direction should the air rise or fall? It's simple.

Upstairs, Chen Xiangyi's answer is correct, but there is a mistake in understanding--- which is also a mistake made by many students, high pressure and low pressure are air pressure situations, and temperature changes will have an impact on air pressure, but the formation of high pressure is not always cooling, and the formation of low pressure is not all heated. Think about these two and you will understand--- Hawaiian high pressure is warm high pressure, while Aleutian low pressure is cold low pressure.

The wind blows from the place where the air pressure is high to the place where the air pressure is low, so the wind direction should be southeast.

The air cools and sinks to form a high pressure, and the heating rises to a low pressure, which AB can exclude.

In the figure, there should be high pressure over the eastern ocean at the same latitude as m (the data are not clear).
