Question

Quizplus · Accepted Answer

Convection refers to vertical motions in the atmosphere that occur when there is instability, usually due to warm air rising and cooler air sinking. This process is driven by buoyancy and is often associated with cumulus clouds and thunderstorms. Subsidence, on the other hand, refers to sinking motions in the atmosphere that occur when the air is stable and often results in clear and dry weather conditions. Cyclonic refers to a type of atmospheric circulation pattern associated with low-pressure systems and counterclockwise wind flow in the Northern Hemisphere. Geostrophic refers to a type of wind flow that occurs when the pressure gradient force is balanced by the Coriolis force, resulting in parallel isobars and a constant wind speed. Convergence refers to the horizontal inflow of air towards a specific location, often associated with low-pressure systems and upward vertical motion.
