Why are the climates different around the world?

The formation of climate is mainly caused by changes in heat. Therefore, there are mainly three aspects of climate formation factors:

1. Radiation factors

< p>Solar radiation is the source of heat energy on the ground and in the atmosphere, and the balance of heat on the ground is an important factor affecting climate formation. For the entire earth, the balance of ground heat is zero, but for different regions, the heat received by the ground is different, which will have an impact on the formation of climate. At the same time, after the ground absorbs heat, it continuously exchanges heat with the atmosphere. Each component in the heat balance process also has an important impact on climate formation.

2. Geographic factors

The influence of geographical factors on climate formation is reflected in the geographical dimension, sea and land distribution, topography and ocean currents. In the final analysis, the influence of geographical factors on climate formation can still be It comes down to the radiation factor. Different geographical dimensions receive different amounts of heat, causing different climates; because oceans and continents have different thermodynamic properties, such as volumetric heat capacity, thermal conductivity, etc., oceans and land are significantly different, so oceans and continents have very different climates. Comparatively speaking, the diurnal and annual variations are greater on the continent than on the ocean. The annual temperature range is an important indicator for distinguishing continental climate and oceanic climate. Moreover, the continent is the heat source in summer and the ocean is the heat source in winter. The heat source is conducive to the formation and strengthening of low-pressure systems, while the cold source is conducive to the formation and strengthening of high-pressure systems. Strengthening, the distribution of sea and land divides the planetary wind belt into several high and low pressure activity centers. These high and low pressure activity centers have an important impact on climate formation. In addition, the different distribution of sea and land also affects weather changes; the impact of terrain on climate formation is, At high altitude, direct solar radiation increases, scattered radiation decreases, temperature decreases, and humidity decreases. Different terrains also have different effects on climate. The influence of plateau on climate is very obvious; and the influence of ocean currents on climate is also caused by heat, and the ocean It is an important storage of heat on the earth's surface.
