| Question | Answer |
|---|---|
| orographic effect | effect that mountains have on weather and climate; blockage of precipitation from the leeward side of mountains |
| cumuliform clouds | dense, white, fluffy, flatbased clouds with a multiple rounded top and a well defined outline, usually formed by the ascent of thermally unstable air masses |
| stratiform clouds | low altitude cloud formation consisting of a horizontal layer of gray clouds |
| precipitation | generally from clouds, the falling of water as liquid (rain) or solid (snow, ice, hail) |
| evaporation | change of phase from liquid to vapor (gas) occurring at the surface of that liquid |
| transpiration | process which adds water to the atmosphere by transpiring, especially through the stromata of plant tissue or the pores of the skin |
| vapor pressure | pressure exerted by water within the atmosphere |
| latent heat | energy released or absorbed during a phase change, such as a liquid to a gas, but with no temperature change involved |
| potential energy | stored energy or energy at rest as a result of its state or position |
| phase change | change of a material through states of solid, liquid, and gas |
| kinetic energy | energy of action, motion, or at work |
| melting | changing from a solid to a liquid state by application of heat or pressure or both |
| freezing | pass from liquid to solid state by loss of heat as in water to ice |
| heat of fusion | amount of latent heat involved in melting or freezing |
| heat of vaporization | amount of latent heat involved in evaporization or condensation |
| specific heat | amount of heat necessary to raise the temperature of 1g of any substance 1°C, measured in calories |
| conduction | transfer of energy, usually heat, by contact from one atom to another atom within a liquid, gas, or solid |
| convection | transfer of energy in gases and liquid due to differences in substances' densities |
| radiation | objects' electromagnetic wave transmission |
| convection cell | circulatory motion in which heat energy is transferred from one place to another due to differences in density |
| current | movement or flow of warm or cold air in a direction |
| radiational cooling | decrease in temperature at the earths surface caused by energy radiating out into space |
