How does the Pacific ocean affect our weather along the U.S. west coast: sea breezes to “ocean-effect” precipitation

The ocean has a big impact on our weather almost every day.  In the winter, large storms are fed energy by the evaporation of water and can generate intense rainfall and hurricane-force winds when they collide with the coastal terrain.  Summer days often end with a simple wind shift that brings cool ocean air inland.  An important part of these weather events is the exchange of energy, water, and momentum between the ocean and atmosphere over the coastal region. This interaction is what makes the coastal climate much different from most of the interior U.S.

In this talk, we will cover the basics of land-sea atmospheric interaction starting with the basic forces that drive air movement.  Using these fundamental concepts, we will explore the various weather events that define the coast al climate in the west.  Topics will include sea-breeze/land-breeze circulation, “ocean-effect” precipitation, ocean upwelling, strong cyclone development and the effect of terrain on coastal winds.
