Latitude, atmospheric circulation, land and sea distribution, ocean currents and topography are the main factors affecting climate. The first two are global zonal factors, while the last three are non-zonal factors.

Latitude is the basic factor affecting climate. Because the earth is a big sphere, the angle of the sun at different latitudes is different. So the solar heat received by different places is different, and the temperature is also very different.

Generally, the lower the latitude, the higher the temperature; The higher the latitude, the lower the temperature. Different latitudes in different regions are the main reasons for different global temperatures. Atmospheric circulation is the main factor that forms various climate types and weather changes.
