GEOG-120 Lecture Notes - Lecture 19: Intertropical Convergence Zone, Northern Hemisphere, Pressure Gradient
Document Summary
Persistent warm, rising air (very little surface wind) River of wind - wild/looping or meandaring. Guides weather patterns ( storms - lifting air as it moves) In different ways/ directions continued santa ana winds (northern hemisphere) Have typical temperature/moisture characteristic that is acquired from a source region. Classified by latitudinal position, which determines moisture content. Classified by surface type which determines moisture content (humidity) Season: fall: october: november mostly cold mass originate just north of nevada. Begins w/high pressure building up over the 4 corner states (utah colorado, arizona, Blocked by the rocky mountains to east; divergent, rotating, sinking air moves over ca. Air gushes through mountain passes; cajon pass, tegon pass, banning pass, speed up. During descent, continued compressional heating occurs (dar to cool, dry air) Rapid warming is also due to friction as air moves through the passes.
