DISCONTINUITY Comparatively large contrast in meteorological elements over a relatively small distance or period of time. In oceanography, it is the abrupt change or jump of a variable at a line or surface.
- A rapid change of a meteorological parameter over distance. A frontal boundary is an example of a .
Discontinuity - A zone characterized by a comparatively rapid transition of meteorological elements.
Dispersion - The separation of colors by refraction.
—A zone with comparatively rapid transition of one or more meteorological elements.
The line of discontinuity, which is developed in suitable conditions between air originating from polar regions and air from low latitudes, and on which the majority of the depressions of temperate latitudes develop.
jump - 1. A in a function or a derivative of a function such that it assumes different values at a point when the point is approached from different directions. 2. See pressure jump.
Cold Front-The discontinuity at the forward edge of and advancing cold air mass that is displacing a warmer and often higher in moisture air mass.
The Polar Front Jet: As its name implies, this jet stream is associated with the marked found at the boundary of well defined air masses - polar to the north/sub tropical to the south (in the northern hemisphere), ...
Fresnel Reflection The reflection of a radar signal from a single, dominating discontinuity of the refractive index, usually with a large horizontal extent.
Front - A narrow transition zone, or boundary, between disparate synoptic scale air masses whose primary is density.
Tropical cyclones occasionally evolve into extratropical lows losing tropical characteristics and become associated with frontal discontinuity.
