GEOG 1900 Exam 2 with Complete Solutions
GEOG 1900 Exam 2 with Complete Solutions Pressure gradient rate of change in pressure across a distance Pressure gradient force the force which results when there is a different in pressure across a surface Coriolis Effect An imaginary deflective force arising from earth's rotation that is necessary to account for motions measured relative to the surface Geostrophic Flow An idealized condition in which the upper-level air flows at a constant speed and direction, parallel to straight isobars. There is no acceleration in geostrophic flow, and frictional forces are negligible. Saturation concept the rate at which molecules move into the liquid phase is the same as the rate at which molecules move into the gas phase (air is saturated) Relative Humidity the actual concentration of water vapor in the air compared to the concentration of water vapor in the air with the same temperature at saturation. - 100 % RH means that air is saturated with water vapor
