GEOG 131 Chapter Notes - Chapter 5.3-5.4: Atmospheric Circulation, Occluded Front, Cool Air
Document Summary
Mid latitude cyclone- larger system of low pressure. Cyclone- any enclosed area of low pressure. Constant pressure map- plots lines to represent the height that you would have to go up in the atmosphere in order to reach a certain pressure: isohypes- the lines, trough- dark, nearly circular area of low pressure. Storm tracks- paths that guide cyclones by large scale patterns of atmospheric circulation across the surface. Occlusion- warmer air mass is lifted above the surface because it is less dense than both the cold air and cool air. Occluded front- front that has experienced occlusion. Lake effect snows- winter storms that interact with the great lakes to produce intense snowfall.
