Document Summary
Chapter 6: atmospheric pressure, wind and global circulation. Air pressure - the force that air molecules exert on a surface due to their weight. Coriolis force - the force created by the earth"s rotation that causes winds to be deflected to the right in the northern. Hemisphere and to the left in the southern hemisphere. Thermohaline circulation - the global oceanic circulatory system that is driven by differences in salinity. What are the 4 factors air flow is controlled by: unequal heating of land surfaces, pressure gradient force, coriolis force, frictional forces (surface friction) How does air flow between pressure centers? (from _____ to _____ pressure) Anything not flat (bldgs, forests, mtns) have friction on wind slows wind speed and pulls it toward low pressure. Aka doldrums or horse latitudes, zone of low pressure around the equator. Warmed by direct sunlight, converging surface air called trade winds from ne & se.
