Document Summary
Stable atmosphere: condition in which air parcels are cooler and denser than the . Unstable atmosphere: condition in which air parcels rise on their own because they are warmer and less dense than the surrounding air: unstable leads to bad weather, elr > dar. Conditionally unstable: dar > elr > mar, latent heat release & mountain ranges. Moving air meets the windward side of a mountain range: forces upward and cools adiabatically. Flows back down leeward side of mountain: warms adiabatically, rain shadows: the dry, leeward side of a mountain range, ways to lift air: Convective uplift: rising of an air parcel that is warmer and less dense than surrounding air. Orographic uplift: rising of air over mountains. Frontal uplift: rising of warm air masses where they meet relatively cold air masses. Convergent uplift: rising of air as a result of converging airflow: the itcz. Most geographically widespread area of convergent uplifts is in the.
