It depends on several things, but usually it's forced upwards. As it rises, the air gets colder. As it gets colder the moisture in the air condenses, first into clouds, then possibly into rain or snow.
Rain or snow.
The water vapor melts and it goes into the mountain
Wind is blowing air up over the mountain. Going from about 1,000 feet at the base to 7,000 feet at the top, the temperature changes as the air goes over the mountain.
it will rain
As A rule the air is moveing in one direction, even though it will change direction momentarilly, All this air is going to travel in A fairly uniform direction, When it hits A mountain The air that is lower to the valley will continue to travel along its path and the mountain will cause it to rise up the side of the mountain, This air will compress the air that is already traveling in the upper levels, pushing the upper air MORE upward, as the air gets toward the top of the mountain, there is so much air trying to pass the mountain that the air will increasingly go upward in A more vertical direction. Is that confusing? I hope someone can make it easier to understand,. The jist is, More air, less room.
While on the earths surface where there's overheating air tends to expand due to high temperature,becomes lighter and therefore rises because the pressure on each molecule is low.But as it ascends the temperature drops at a rate of 6.5 degrees celsius per km.This is reffered to as the "Lapse rate". At the "Peak" or highest point of a mountain,the air has lost much heat because the higher it goes the cooller it becomes.The air becomes cold,dense,and heavier with a high pressure.In casses like this the air may condense to form rainfall and if it condenses below 0 degree it forms snow.
Air evaporates
It gets cool beacause the air is thinner and cant hold as much heat.
air pressure on the high mountain is because air flow is fast or velocity of air is more on the high mountain
it decreases
is decreases
air.
Orographic effect
as the altitude increases density of air decreases.This makes it harder to breath.
The air pressure slowly decreases as you rise in altitude.
From what I recall, the air at the bottom of a mountain is usually warmer, wetter, and more oxygenated. The air at the top gets less of these three depending on as high up as you go.
