GEO 1200 Lecture Notes - Lecture 2: Urban Heat Island, Solar Irradiance, Heat Transfer
Document Summary
U. v: invisible light, more insolation, higher energy, shorter wavelengths. Thermal heat transfer: march, highest heal transfer in the equator. Equinox: march 21st devember 21st north and south hemispheres receive equal amount of heat and sunlight. Five factors that influence into a location"s air temperature: Depends on amount of gases in the air. The way that all of the atoms in air hold energy or heat. If a substance receives a flow of energy, kinetic energy increases and temperature increases. We never add cold, we always add heat. Coolest time of day is before the sun rises, the energy starts to rise, and then you get negative insolation at night. Air temperature is measured under standard conditions at 4 ft above the ground. Max and min temperatures are recorded, you get the mean (average) to get mean daily temperature. 8 am- temperature is same for soil and air.
