Document Summary

Inter tropical convergence zone: example in northern hemisphere in summer. Itcz moves pole ward and subtropics get abundant rainfall: example in northern hemisphere in winter. Subtropical highs intensify and grow in summer because conditions which are initially cooler over the oceans. Eastern side of tropical high are dries where as west side of subtropical high are moisture: northern hemisphere in winter. Land is cold in winter and high pressure occurs over land, low pressure occurs over ocean. North pacific is dominated by aleution low and north atlantic dominated by icelandic low: northern hemisphere in summer. Land is warmer in summer, low pressure = land, high pressure = ocean. North pacific is dominated by hawaiian high and north atlantic dominated by azores high: southern hemisphere. Antarctica is always cold as a result there is always high pressure over antarctica. Winter months ( july) similar to summer months ( jan: air circulation.
