– Delayed

– Deepening. Usually in reference to a low pressure intensifying.

– A type of weather radar that determines whether atmospheric motion is toward or away from the radar. It uses the Doppler effect to measure the velocity of particles suspended in the atmosphere.

– A strong downdraft of air which induces an outburst of damaging winds on or near the ground.

– An uneven distribution of snowfall/snow depth caused by strong surface winds, but does not reduce surface visibility.

– Fairly uniform precipitation composed exclusively of fine drops very close together. Drizzle appears to float while following air currents; however unlike fog droplets, it falls to the ground. Drizzle drops are too small to disturb appreciably still water puddles.

– Refers to a influx of dry air (especially toward a mid-latitude cyclone)

– Refers to upward forcing caused by jet streak divergence or PDVA
