Mountains have two effects on precipitation. These are the rain shadow effect and the orographic effect. These both cause the type and amount of precipitation to change because the air is forced higher up.

A mountain range, if tall enough acts like a rain catcher. It will force water vapor and rain to fall on one side of the mountain before the weather system can move on. End result is lots of rain on one side of the mountain, not nearly as much on the other. A good example of this is the Sierra Nevada mountains, lush on one side, desert on the other.

As the water vapor moves through the air, the mountains will stand in the way of the many water molecules moving towards them. The result is that the water molecules will condense in one area, making them likely to fall as rain. The land on the other side of the mountains won't get as much water vapor as the first one, meaning that the land without as much water vapor will get less rain.

High mountains interrupt the clouds passing and affect the amount of precipitation that falls over the area. Another factor affects the amount of precipitation is wind. The windward side of a mountain receives more rainfall than the leeward side.

Mountains cause precipitation by allowing clouds to form on one side of the mountain. The allow the air to rise enough which is then condensed into water vapor and causes precipitation.

How do landforms and land masses affect precipitation?

Rain clouds are often forced to rise as winds blow them towards landforms like mountains. Clouds rising are unable to hold their water, so it falls as precipitation on the windward side of mountains.

How does the temperature of the air affect the amount of humidity that you feel How does the air's temperature also influence the form of precipitation that falls?

The higher the temperature of the air the higher the amount of humidity you feel. Also the colder the airs temperature it can cause precipitation such as hail, snow, and sleet rather then just rain.


Are the eastern mountains drier than the western mountains?

Generally, yes. The rain shadow effect causes the eastern side of mountains to be drier than the western side. As moist air rises over the mountains, it cools and releases most of its moisture on the windward side (western side), leaving the leeward side (eastern side) drier.
