What is the distribution law of world temperature?

The distribution law of world temperature is gradually decreasing or increasing from low latitude to high latitude.

The highest average temperature in the world is located in the north of Africa, which is influenced by latitude and land and sea factors. The temperature at low latitude is high, and the temperature at high latitude is low or decreases from low latitude to high latitude. At the same latitude, the land temperature is high and the ocean temperature is low in summer. In winter, on the contrary, the temperature decreases with the elevation. The hemisphere is tortuous and the southern hemisphere is flat. Because of the land and sea in the northern hemisphere, the underlying surface properties are quite different, and the isotherm deviates from latitude.

Natural factors:

The temperature in a certain place changes periodically not only because of the change of solar radiation, but also because of the movement of the atmosphere rather than periodically. The change of actual temperature is the result of the interaction between these two aspects. If the former plays a big role, the temperature changes periodically; On the contrary, it shows an aperiodic change.

However, from the general trend and most cases, the periodicity of daily and annual temperature changes is still the main one. Various components in the heat balance, such as radiation difference, latent heat and sensible heat exchange, are affected by different control factors. Astronomical factors such as latitude and season have obvious zonal and periodic characteristics.

However, the nature, topography and weather conditions of the underlying surface, such as cloud cover and atmospheric humidity, all have non-zonal characteristics. At the same time, the influence of these factors is different in different places, so the temperature distribution caused by the change of heat budget is also uneven.
