Rossby wave — Rossby (or planetary) waves are giant meanders in high altitude winds that are a major influence on weather. Their emergence is due to shear in rotating fluids, so that the Coriolis force changes along the sheared coordinate. In planetary… … Wikipedia
Rossby-Zahl — Die Rossby Zahl (Ro und nicht R0, nach Carl Gustaf Rossby) ist eine dimensionslose Kennzahl, die vorwiegend in der Geophysik bei ozeanografischen und atmosphärischen Phänomenen Verwendung findet. Sie gibt den Einfluss der Erdrotation an, das… … Deutsch Wikipedia
Rossby-Wellen — Rọssby Wellen [nach C. G. A. Rossby], 1) Meereskunde: großräumige Meereswellen, deren rücktreibende Kraft aus räumlichen Änderungen des Verhältnisses von Coriolis Parameter (Coriolis Kraft) und Wassertiefe resultiert. Rossby Wellen stellen… … Universal-Lexikon
Rossby radius of deformation — In atmospheric dynamics and oceanography, the Rossby radius of deformation is the length scale at which rotational effects become as important as buoyancy effects in the evolution of the flow about some disturbance. : L {R} equiv frac{NH}{f {0,… … Wikipedia
Carl-Gustaf Rossby — Carl Gustaf Arvid Rossby (Stockholm 28 December, 1898 ndash; Stockholm 19 August, 1957) was a Swedish U.S. meteorologist who first explained the large scale motions of the atmosphere in terms of fluid mechanics.Rossby came into meteorology and… … Wikipedia

Balanced flow — In atmospheric science, balanced flow is an idealisation of atmospheric motion. The idealisation consists in considering the behaviour of one isolated parcel of air having constant density, its motion on a horizontal plane subject to selected… … Wikipedia
Cnoidal wave — US Army bombers flying over near periodic swell in shallow water, close to the Panama coast (1933). The sharp crests and very flat troughs are characteristic for cnoidal waves. In fluid dynamics, a cnoidal wave is a nonlinear and exact periodic… … Wikipedia
