Document Summary
Low because the pressure decreases more slowly in the air column, and the pgf is moving air out of the warm air column. When the air is moved out, lower points experience lower pressure. Higher at the troposphere because evenly distributed throughout warm air column. They are an area of surface low pressure, little wind, and are located along the equator. Usually show up as a line of thunderstorms. These are areas of surface high pressure with no winds. Air is rising at 0 and 60 (warm air rises) Warm air is rising and cold air is sinking. (this explains the low pressure at the surface of the equator) Is there a pgf at the center of a hurricane? no. 2. dust devils, tornadoes, tstorms- m-km: land/sea breeze, chinook, santa ana- 10"s-100"s km, trop storms, hurricanes- 100"s of km, h&l areas on tv weather- 1000"s of km, long waves- plantetary.
