Read "Four Schematic Diagram of Temperature Difference between Day and Night" and answer the question: Question 1: The reasons why the temperature is not too high on cloudy days in summer are as follows: a. Clouds radiate to the sun.

Question 1:B

Question 2:B

Question 3:C

Test analysis:

Question 1: In summer, it is cloudy during the day and the temperature is not high, mainly because of the strong reflection of clouds, so there is less solar radiation reaching the ground and the temperature will not be too high.

Problem 2: Because there are few clouds in sunny nights, the atmospheric inverse radiation is weak, and the heat preservation effect is poor, it is easy to frost when the temperature drops suddenly at night.

Question 3: During the day, the weather is clear, there are few clouds, the atmosphere has a weak weakening effect on solar radiation, and the temperature is high; When it is partly cloudy at night, the atmospheric inverse radiation is weak and the heat preservation effect is poor, so the temperature is low, so it is sunny day and night, and the temperature difference between day and night is the largest.

Comments: This problem is generally difficult, and the key to solve it is to judge weather examples by combining the thermal effect of the atmosphere. For this kind of questions, students should strengthen the implementation of the basic knowledge of textbooks.
