ADVECTION- The increasing or decreasing of advection with height. Vorticity advection increasing with height is favorable for uplift as well as warm air advection increasing when moving from aloft to the surface.

– A 2-D process in which airstreams spread apart.

– Deepening, becoming more amplified with time. Often in reference to a trough deepening and building to the South.

– a disruption of the atmosphere that usually refers to a low pressure area, cool air and inclement weather.

– A reference to an effect that has its origins due to daytime heating, such as afternoon cumulus cloud development or the formation of a lake/sea breeze. These phenomena dissipate once the sun goes down and surface heating is lost.

– refers to the spreading out of winds.

– Diverging Q vectors. Indicates air will sink due to low level cold air advection and/or upper level convergence
