| | The Weather Notebook: Rain Shadows (Site not responding. Last check: 2007-11-05) |
 | | When moist Pacific air hits the wall of the Olympic Mountain range, it rises and cools, and the cooling causes the water vapor to condense and fall as rain...lots and lots of rain, especially in the winter months when the active jet stream funnels in one storm after another. |
 | | But as soon as these juicy air masses cross the 5,000 to 8,000 foot Olympic crest, mostly from southwest to northeast, the process goes into reverse: the air warms as it descends, clouds disperse, sun peeks through, and the landscape looks thirsty. |
 | | Rain shadows exist wherever mountains intercept a flow of moist air: the Cascade and Sierra ranges cast a rain shadow on the three Pacific states, and the Great Plains parch in the rain shadow of the Rockies. |
