How does a mountain range affect the weather and pollution of a city?

Some cities are surrounded by mountains which can sort of trap air flow or block it from coming in. How does that affect the city?

    Mountains can affect weather patterns in the surrounding area by forcing clouds to deposit all of their moisture on one side of the mountain. This leads to a luscious and well watered slope and valley on one side of the mountain but deprives the other side of moisture. This can turn the un-watered side into a very arid and desert-like environment.

    This “rain-shadow” effect is very well illustrated in the Sierra Nevada mountains in California. The redwood forest grow on one side of the mountain range while the other side is known as death valley.
