Document Summary
Measure of the level of sensible heat (gas, liquid, solid) First thermometer invented by galileo in 1592. Upper boundary and coldest part of the atmosphere (-90. Small changes in solar energy= large changes in temperature. Key variables of temperature: insolation, latitude (tilt, rotation, cloud cover, surface type, proximity to water, elevation, slope and aspect. Thermal properties =temperature difference coast and interior. Coastal temperatures less variable day/night and summer/winter. Earth"s revolution + tilt = annual cycle of net radiation. E. g: areas of perpetual ice and snow are always intensely cold e. g. isotherms make a large n-s shift from january to july over, isotherm patterns are associated with ocean currents. Rockies and andes polar regions continents in the mid-lat. Bubbles of gas in ice e. g. ghg conc. Measure ring width and match patterns in growth. Historic documents are valuable sources of past climate.
