Document Summary
Part 1 thermal winds: land/sea breeze: toronto, monsoon, valley breeze, foehn/chinook, katabatic wind. Valley breeze: breezes develop in a valley on a diurnal basis, during the day, uphill wind and during the night downhill wind by the sides of the valley. Katabatic winds: form in glaciated regions, air pools over the glaciers and becomes denser, as air moves away from the glaciers, dense air moves rapidly downhill (very cold) Chinook: pre-eminently canadian wind, occurs on lee side of the mountain (calgary and alberta, rapid phase change; can cause drastic changes in temperatures during the winter. Urban heat island: warming of urban areas compared to surrounding areas, noticeable at night and in the winter, more intense when winds are weak. Research paper: trends in temperature time series in the gta, by mohsin t. and gough w. 2009. Increased air pollution and ozone: higher living costs due to higher water and energy use.
