 A Kilometer is equal to (miles) 2/3 of a mile The Troposhere Is the lowest layer gets colder with elevation The Stratosphere The 2nd layer Gets warmer with elevation The Mesosphere The 3rd layer gets colder The Thermosphere The Outer layer gets warmer 99% of the earths atmosphere are made of these gases Nitrogen (78%) and Oxygen (21%) L Storm. counter clockwise and inward kinetic energy is defined as the energy within a body that is the result of motion cold air is more dense heat is released into the environment with condensation and freezing Conduction transfer of heat from molecule to molecule with in a substance; contact is needed (one moving fast hits one moving slow, moving slow will take heat and move as fast) Convection transfer of heat by the mass movement of a fluid (in the vertical); similar to a pot of boiling water Advection - transfer of heat or properties from one part to another part (in the horizontal) usually by the prevailing wind Radiation transfer of energy from one object to another without spaces in between heated; no contact is necessary released by EVERYTHING Blackbody Releases the same amount of radiation that it absorbs Thermal Belt In a Valley, cold, warm, cold Vertical Cross-Section Both Vertical and Horizontal Vertical Profile a graph that displays one or more variables as a function of the distance above the earth over a single point. Heating degree-day Based on the assumption that people will begin to use their furnaces when the mean daily temperature drops below 65F. Determined by subtracting the average temperature of the day from 65F. Example: If the mean high was 63F then the heating degree-day is 2 Cooling degree-day Based on the assumption that people will begin to use their air conditioners when the mean daily temperature rises above 65F. Determined by subtracting 65F from the daily average temperature. Growing degree-day Based on the approximate number of days for a certain plant to fully grow for harvest. Computed by using a base temperature where the plant can grow (daily mean temp - base temp). Albedo is the percent of radiation returning from a given surface compared to the amount of radiation initially striking the surface. (reflectivity of a surface) Local and worldwide albedo North of 30, deficit South of 30, surplus Solstice both on 21 Equinox March 20 Sept 22 Electro-magnetic spectrum Infrared Visible UV Inversion warmer with height Lapse rate colder with height Isothermal stays the same with height
