GEOG 1040H Lecture Notes - Lecture 3: Barometer, Thermal Equator, Anemometer
Document Summary
Atmospheric circulation (sensible and latent heat exchange) Circulation driven by temperature and pressure differences across the globe. Insolation (solar radiation: altitude, high altitude has greater daily range and lower annual average temperature, cloud cover, high albedo, moderates temperatures cooler days, warmer nights, clouds are effective absorbers of long wave radiation. Continentality temperature conditions more extreme- land warms and cools quickly. Marine temperature conditions more moderate water warms and cools slowly. Ocean is transparent: water can hold more heat than soil or rock, water gains heat slowly and loses heat slowly, water can mix cool and warm. Marine and continental climates: winnipeg is continental, victoria is marine. Thermal equator zone of highest mean temperature over the earth. Humidity - how much water vapor the air can hold. Correlates sensed cold temperature and wind speed. More discomfort with high wind and high humidity: air pressure and its measure, mercury barometer, aneroid barometer, wind: description and measure, wind, anemometer, wind vein.
