Temperature distribution law

The temperature distribution law is as follows:

I. Latitude distribution law

There are obvious differences in the temperature distribution at different latitudes of the earth. Generally speaking, the temperature in low latitudes is higher than that in high latitudes. This is because low latitudes receive more solar radiation energy, while high latitudes receive less energy. In addition, the seasonal changes in different hemispheres are also different. For example, summer and winter in the northern hemisphere appear in winter and summer in the southern hemisphere respectively.

Second, the law of land and sea distribution

There are also differences in temperature distribution between the ocean and the land. Generally speaking, marine climate has less temperature change and higher humidity than continental climate. In summer, the temperature on land is higher than that on the ocean, but it is the opposite in winter. In addition, the temperature variation in coastal areas is usually smaller than that in inland areas.

Third, the height distribution law

The temperature varies with height. Generally speaking, the higher the height, the lower the temperature. This is because with the increase of altitude, the atmospheric pressure decreases and the molecular density of air decreases, which makes it difficult to transfer energy in the air. In low latitudes, this change is usually not obvious, while in high latitudes, it shows obvious vertical decline rate.

Fourth, the law of time change.

The temperature changes regularly throughout the day. The temperature rises gradually after sunrise, reaches the highest value in the afternoon, and decreases gradually before and after sunset. In addition, due to seasonal changes, the highest and lowest temperatures appear at different times in a year.

Five, the temperature distribution law

The daily range in different areas is different from that in annual range. Generally speaking, the temperature difference in inland areas is greater than that in coastal areas, because the air in inland areas is drier than that in coastal areas and lacks moisture. In arid areas, the temperature difference may be greater. On the contrary, in humid areas, the temperature difference may be small due to the existence of moisture.

To sum up, the law of temperature distribution is one of the important concepts in geography and meteorology, which describes the temperature change and distribution in different parts of the earth at different times. Understanding these laws will help us better understand important issues such as climate change and weather forecast.
