Document Summary
Global circulations: the global atmospheric circulation and its seasonal variability is driven by the uneven sola(cid:396) heati(cid:374)g of the ea(cid:396)th"s at(cid:373)osphe(cid:396)e a(cid:374)d su(cid:396)fa(cid:272)e. Planet axial inclinations: solar radiation on a planet at different axial inclination. The concept of flux density (1/d2, energy/time/area) and the cosine law. Seasonal variability: be(cid:272)ause ea(cid:396)th"s (cid:396)otatio(cid:374) a(cid:454)is is tilted (cid:396)elati(cid:448)e to the pla(cid:374)e of its o(cid:396)(cid:271)it a(cid:396)ou(cid:374)d the su(cid:374), there is seasonal variability in the geographical distribution of sunshine. Solar radiation: the geographical distribution of temperature and its seasonal variability closely follows the geographical distribution of sunshine (solar radiation) In addition to understanding how temperature affects atmospheric circulation, we also need to understand one of the basic forces governing air and water motion on earth: The coriolis force: but to understand this affect, we first need to review the concept of angular momentum conservation. In los angeles (latitude 34on), an object is moving at a speed of about 1400 km/hr (= 860 miles/hr)
