Document Summary
October 24th: political ecology of the urban climate. Toronto has no single prevailing wind; it shifts seasonally. In classic winter weather, we get dry, cold wind from the nw; these are the strongest winds in toronto, and they"re also accelerated through the gaps between the buildings. In classic summer weather, warm, we get moist winds form the sw. The venturi effect: buildings can, of course, create shelter from wind. But they can also accelerate winds by funnelling. York in particular has this problem - its a notoriously windy campus, with no buildings designed considering the venturi effect. In toronto, we tend to construct along a street grid, which is perfect to create urban canyons, and therefore windy intersections. In victorian times, the unpaved clay-based streets of toronto had summer dust problems and winter mud problems. The worst one was considered to be the queen and bay intersection. In edwardian toronto, skyscrapers started to be built.
