Causes of temperature difference change after comet hit the earth

From the point of view of atmospheric heating, this paper analyzes the temperature difference between day and night on the earth's surface before and after the comet hits the earth, and explains the reasons. Answer: The analysis of temperature difference between day and night should be based on the principle of atmospheric heating process, mainly from the aspects of topography, weather conditions, underlying surface properties and so on. (1) The terrain is high → the atmosphere is thin → the weakening effect of the atmosphere during the day and the heat preservation effect of the atmosphere at night are weak → the temperature difference between day and night is large. (2) Weather conditions: Under sunny weather conditions, the weakening effect of the daytime atmosphere and the heat preservation effect of the nighttime atmosphere are weak → the temperature difference between day and night is large. (3) Properties of the underlying surface: the specific heat capacity of the underlying surface is large → the heating and cooling rate is slow → the temperature difference between day and night is small, for example, the temperature difference between day and night in the ocean is generally smaller than that on land. Cause: This is mainly caused by solar radiation. During the day, the sun shines on the ground to generate heat, which is reflected into the atmosphere, causing the temperature to rise. There is no sun at night, and the source without heat in the atmosphere has a low temperature.
