In the visible light image, find the cloudless area off the coast of Oregon and Washington. Does this region contain relatively large amounts of water vapor, or relatively little water vapor? (Hint: Compare the visible light and water vapor images.) What could explain the lack of clouds here?

The question is based on Figure 20-3 showing visible light, infrared, and water vapor images of western North America and the northern Pacific Ocean basin taken on the same day and time.
What will be an ideal response?


Large amounts of water vapor. Lack of uplift mechanism; high pressure in area; air not yet cooled to dew point temperature.
