Pecipitation is influenced by geoegraphic location, elevation and aspect. Pecipitation increases in areas of high humidity, as well as areas with high elvation and a eastern aspect.
When air becomes saturated with moisture it wants to precipitate, that is condense and fall. If the air is not saturated there will be little force to cause precipitation. High moisture levels in the...
Humidity - increased humidity decreases transpiration, as the air is already saturated with water, and so the water potential gradient is smaller, and so less water is lost by transpiration....
