Influence of Continents   ,[object Object],[object Object],[object Object],[object Object],[object Object]
[object Object],[object Object]
During the  summer , the air over the continent becomes much warmer than the water surface, so the surface air moves from the water to the land. The humid air from the water converges with dry air from over the continent and  produces precipitation over the region,  over  400 inches at some locations ! During the winter the flow reverses and the dominant surface flow moves from the land to the water.
