Document Summary
Takeaways: know the physical phenomena which influence climate and weather, be aware of the economical consequences of severe weather. Climate meteorological elements and phenomena averaged over a long period of time for a region of the earth"s surface. Factors influencing climate: meteorological elements: precipitations, temperature, humidity, etc, phenomena: hail, frost, fog, etc, long-term trends in heating and cooling of the earth"s surface, circulation of the atmosphere and oceans. Ontario shares similar climate with quebec and part of manitoba. Climate in ottawa: humid continental climate, four distinct seasons. Energy balance between the sun and the earth: balance must be maintained at a certain point in time. Energy entering the earth"s atmosphere must equal the energy re-emitted to space otherwise global warming/cooling: energy balance at the top of the atmosphere. Albedo amount of energy reflected back into space. 0 = irradiation (100%) - albedo% - energy absorbed by atmosphere and earth"s surface% Greenhouse effect energy radiated by earth"s surface and reflected back.
