ATS 350 Midterm 2 Test Questions and Answers Solved Correctly Latest Version Latent heat - Answers Heat required to convert a solid into a liquid or vapor without change of temperature Relative humidity - Answers Actual vapor pressure/saturation vapor pressure Fog - Answers When air temperature lowers to dewpoint, water vapor can condense into small droplets Radiation fog - Answers Air cools to dewpoint due to IR radiation to space Advection fog - Answers Warm air flows over cold water or cold ground Mixing fog - Answers Cold air moves over a warmer body of water, water evaps, saturation is reached Upslope fog - Answers Air is forced up along terrain and cools, saturation is reached Cumulus - Answers Heap or pile Stratus - Answers Flatten Cirrus - Answers Horse hair Nimbus - Answers Precipitating Altum - Answers Height Four mechanisms that lead to formation of clouds - Answers Orographic lifting, convection, convergence and updraft Lifting condensation level - Answers The altitude at which condensation begins (the temperature of the rising air parcel reaches the dew point temperature) Level of free convection - Answers the height to which a parcel of air must be lifted for it to become buoyant and to rise on its own Adiabatic process - Answers A process in which no heat is transferred to or from the system by its surroundings. Moist adiabatic lapse rate - Answers 6 degrees C/km Dry adiabatic lapse rate - Answers 10 degrees C/km Environmental lapse rate - Answers Change in environmental temperature with height Parcel lapse rate - Answers How the temperature within an air parcel changes when it is displaced vertically How can instability be increased in the atmosphere - Answers Heat the surface Absolutely stable atmosphere - Answers Environmental lapse rate is less than moist adiabatic lapse rate Absolutely unstable atmosphere - Answers Environmental lapse rate is greater than the dry adiabatic lapse rate Conditional instability - Answers moist air with a lapse rate between the dry and wet adiabatic rates
