GGR214H5 Study Guide - Final Guide: June Solstice, Polar Easterlies, Frontolysis
Document Summary
Incoming and outgoing radiation are not balanced at individual latitudes. Earth and westerly winds of the mid latitudes lose momentum to earth. Momentum is the product of mass and velocity. Angular momentum: the product of mass, is conserved in a rotating system. (right side) if we want to conserve momentum, it must be transferred: ex. Transferred from the easterly winds to the westerly winds to maintain. M v r current momentum. The general circulation: must transport both energy and momentum toward the. Mid-latitudes: accomplished by weather systems in the form or eddies and poles. waves. Simple case : the sun is, earth"s surface. Equatorial low: or intertropical convergence zone (itcz) is where trade winds from two hemisphere converges. Mid-latitude westerlies: are created between subtropical highs and subpolar lows they experience much greater deflection because poleward increases the strength of coriolis force. Polar esterlies: are created between polar highs and subpolar lows.
