Document Summary
Climate: long term average weather, determined by solar radiation + global patterns of wind & ocean circulation + topography; most fundamental component of physical environ. Weather: current condition of an area e. g. temp, rainfall. Orbital forcing vs solar insolation // tilted axis vs elliptical orbit = sun & equator =/= always 90 degrees i. e. ch @ insolation cuz 1. Polar cell: surface winds @ poles being driven by cool air descending. @ temperate region = polar cell @ n + hadley cell @ s -> drives cell i. e. wind moving away from equator. Rising air cools -> rainfall vs descending air warms -> takes up moisture -> arid climate. Trade wind vs westerlies = blow e -> w -> meet @ equator i. e. itcz => signi cance: bring ship from europe to ca vs @ mid-latitude -> blow w -> e -> bal trade wind. => explains why large storm systems e. g. hurricane spin (thermohaline circulation)
