In what part of the earth does the temperature rise as you move from south to north?

Our planet is spherical, the angle of incidence of sun rays on its surface varies from the equator to the poles. In the equator and the tropics, the sun’s rays fall almost at right angles, and in the polar zones they only glide along the surface at an acute angle. Therefore, the average annual temperatures also vary from the equator to the poles.
The expression “warmer in the south” will only be correct for the northern hemisphere. In the southern hemisphere, temperatures increase as you move from south to north, from the south pole to the equator.
