CPAER Meteorology Questions and Answers Already Passed What is the primary driver of weather? Uneven heating of the surface of the earth In a standard atmosphere the environmental lapse rate is 2o per 1,000ft The dry adiabatic lapse rate is 3o per 1,000ft The wet adiabatic lapse rate is 1.5o per 1,000ft A stable atmosphere occurs when the environmental lapse rate is Shallow or negative An unstable atmosphere occurs when the environmental lapse rate is Steeper than both the wet and dry adiabatic lapse rates A potentially unstable atmosphere occurs when the environmental lapse rate is Somewhere between the dry an wet adiabatic lapse rates ISA 15o and pressure at sea level of 29.92" (1013.2hpa) The average height of the tropopause is 36,000ft For every 1,000ft climbed, mercury drops approximately 1" Relative humidity The amount of water in the air relative to the maximum it can hold at given temperature and pressure Dewpoint The temperature at which condensation begins Is humid air or dry air more dense? Dry air Convection Vertical movement of air Advection Horizontal movement of air Deposition When gas changes *directly* to a solid Isobars Lines of constant/equal pressure Isotachs Lines of constant/equal wind velocity
