Document Summary
Questions: 1-3, 5, 7, 9-11, on page 235. Worldwide average flow of air or climatology of global winds. Warm air rises at equator and sinks at poles: northerly wind at surface and southerly wind aloft o. Low at the equator and a high at the poles (there for, the idea that air moves from a high to a low generates a convection cell) Rotating earth - three cell model: water surface. Westerly comes from the west but is traveling east. Reality - one cell model + stuff Swirls (eddies) is where the weather is. Where the high sinks - the weather is dry (reason why there are so many deserts at 30 o. If it were not for the gulf, texas would be a desert. If hadley cell expanded: college station would become a desert, and the northern states could grow more because the cold weather would be pushed up further north.
