A type of weather warning formerly issued by the U.S. National Weather Service to alert areas in which a high rate of snowfall (generally 6 in (15 cm) or more in 12 hours) was occurring or was forecast. The warning was replaced by the Winter Storm Warning for Heavy Snow beginning with the 2008–09 winter storm season. helicity high-pressure area
The first term is equal to the change in temperature due to incoming solar radiation and outgoing longwave radiation, which changes with time throughout the day. The second, third, and fourth terms are due to advection. Additionally, the variable T with subscript is the change in temperature on that plane.
Therefore, the increased momentum (due to enhanced wind stress) is diverted into the oceanic mesoscale and transferred to the bottom of the ocean instead of the horizontal mean flow. [11] This flattens isopycnals (reduces buoyancy forcing) and therefore slows down the mean flow. This phenomenon is known as eddy saturation.

In the atmosphere, convective momentum transport by small but vigorous (cumulus type) cloudy updrafts can be understood as an interplay of three main mechanisms: Vertical advection of ambient momentum due to subsidence of environmental air that compensates the in-cloud upward mass flux, Detrainment of in-cloud momentum where updrafts stop ...
1. Two Bizarre Desert Floods. 2024 was a terrible year for deadly floods. We previously mentioned the mainland U.S. had its deadliest tropical cyclone-spawned flood since Katrina.
A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and include weather systems such as tropical cyclones, squall lines, lake-effect snow events, polar lows, and mesoscale convective complexes (MCCs), and generally forms near weather fronts. The type that forms during the warm season over ...
Springlike weather is just around the corner with warmer days, budding plants and blooming flowers. However, don't put away your snow boots and winter coats just yet, the changing of the seasons ...
