A scale that is between local and regional scales of influence.
A scale used in meteorology that extends from approximately 1 to 100 km (.7 to 67 miles). Mesoscale features include such things as thunderstorms, sea breezes, gust fronts and macrobursts.
Used to describe weather systems that lie in between synoptic scale and local scale. This generally means weather features that are between 25km and 250km in size. Examples of mesoscale systems are mesoscale convective systems (MCS), squall lines and southerly busters. A mesoscale model will have a grid resolution small enough to resolve these features. This usually means a resolution of 25km or smaller. See also meso laps
The scale of meteorological phenomena that includes MCCs, MCSs, and squall lines. These weather systems may cover fifty to several hundreds of miles. Smaller phenomena are classified as storms, while larger are classified as synoptic-scale.
Scale of meteorological phenomena that range in size from a few km to about 100 km.
In meteorology, weather systems and events up to about 250 miles in diameter.
of or relating to meteorological phenomena approximately 2 to 200 kilometers in horizontal extent; thunderstorms and squall lines are two examples of mesoscale events
Between roughly 10 and 1000 km in horizontal dimensions, about the size of an average state.
A length dimension associated with a circulation feature, typically of the order of 100-1,000 km; the scale upon which ocean eddies and hurricanes occur.
Size scale referring to weather systems smaller than synoptic-scale systems but larger than storm-scale systems. Horizontal dimensions generally range from around 50 miles to several hundred miles. Squall lines, MCCs, and MCSs are examples of mesoscale weather systems.
Pertaining to atmospheric phenomena having horizontal scales ranging from a few to several hundred kilometers, including thunderstorms, squall lines, fronts, precipitation bands in tropical and extratropical cyclones, and topographically generated weather systems such as mountain waves and sea and land breezes.
A generic term for describing the spatial extent of a meteorological phenomenon, generally encompassing the range 100 to 1000 km.
A middle-sized event that usually is measured in 10's of miles and hours of time; a thunderstorm-sized phenomenon; e.g. thunderstorms and sea breeze circulations.
A small scale weather system, covering a portion of a state or region, often caused by local terrain.
The scale of meteorological phenomena that range in size from several kilometers to around 100 kilometers. This includes MCCs, MCSs, and squall lines. Smaller phenomena are classified as microscale while larger are classified as synoptic-scale.
