GGR100H1 Lecture Notes - Lecture 5: Evaporation, Boiling Point, Kelvin
Document Summary
Temperature affects societies, decision-making, and resources consumed across the globe. Understanding temperature concepts helps us continue out study of related earth energy, weather, and climate systems. We look at the principal temperature controls or latitude, altitude and elevation, cloud cover, and land-water heating differences that interact to produce earth"s temperature patterns. We end by examining the effect of temperature on the human body and discussing current temperature trends associated with global warming. Shortwave and longwave images show earth"s radiation budget components. Shortwave out greatest tropic of cancer & capricorn (no equator or poles) Longwave out greatest tropic of cancer & capricorn (w/ equator, no poles) Subtropical desert regions exhibit: greater longwave radiation out b/c of little cloud cover, greater radiated energy losses from surfaces that absorb high amounts of energy. Regionally, and seasonally earth absorbs more energy in the tropics and less in the polar regions = this drives global circulation.
