A high pressure air mass moves into an area, What kind of weather can we expect?
Clear skies and sunny.
Mrs. Harrison's hometown in eastern Washington has a dry climate, in contrast to Seattle on the western side of the state. Explain why.
Landforms such as mountains can affect local weather patterns by directing the moisture-filled air upward into the cooler atmosphere where the cooled water vapor condenses to form rain, creating a wet climate for one side of the mountain range. This also causes the area on the other side of the mountains to receive little rainfall as the air that flows over the mountains has released its moisture. The direction of wind flow determines which side of a mountain range receives moisture and which side has dry conditions.
