Temperature control lever
solar radiation and thermal energy
There might be a blend door issue causing you to have cold air, but no hot air. Try moving the lever from cold to hot, and listen for the sound of the door moving.
Cold front.
Convection
the thing that causes it is that masses of air would stay and change the weather of that specific weather
The temperature changes from hot to cold or cold to hot. this makes a wind push air across the earths crust
There is a door behind the dash that changes cold and hot air flows. The door is probable stuck or the control circuit has failed causing the hot air to blow on cold.
the body temperature changes because of its surroundings
space cold air has greater air pressure height above earth and moist are that has less air pressure
its probably the dual air conditioning door lever the little motors go bad or its the control switch on your console
temperature affects air pressure when it is cold air pressure decreases when it gets warm air pressures rises
When fronts meet from the opposite and collide, it is called an occluded front. A cold occluded front is cold air shoving under cool air at the Earth's surface thus the name 'cold occlusion'. The cold warm air boundary aloft is often west of the surface front. A warm occlusion is when cool air rises over cold air at the surface thus the name 'warm occlusion'. The warm-cold air boundary aloft is often east of the surface front. By Lisa Gardiner
