In physics, how to explain that cold air mass from polar area make the temperature of the warmer place lower?

since in physics, hotter objects transfer heat to colder objects?





why does cold air mass make the warm air in the temperate region colder?|||im glad u understood that cos i didnt. If you ahve 2 identical objects 1 of them at 10 degrees and the other at 50 the hot one will transfer some of its heat to the cold one. After a while they will be in thermal equillibrium and both be 30 degrees.|||At both poles, a thermal air flow occurs. At ground level this air tries to flow from the poles towards the equator, but turns relative to the earth because of the Coriolis effect. However, there is still a southerly component to it, considering the north polar area only. So when the flow moves south from the north pole, it encounters warmer air at a lower latitude.

Heat in this area is diluted by the colder air, so temperature lowers. But this air is still warm in comparison to the colder polar air. It rises, and flows back towards the poles. There, it is cooled, and again drops and continues in the cycle.

Thus by convection, the warmer air at the lower latitudes is cooled by the polar air.

This particular convectional transfer system is known as the "polar cell". There are 2 further such cells each side of the equator, the "mid- latitude" and the "tropical" or "Hadley" cell.|||Because as you said the hotter objects (warmer air) loses their heat energy to the colder objects (colder air) so the hotter air becomes colder.
