ROSSBY WAVES The movement of ridges and troughs in the upper wind patterns, primarily the jet stream, circling the earth. Named for Carl-Gustaf Rossby, a U.S.
Rossby waves - the large lobes, about a thousand miles wide, in the waves circulating the earth.
Rossby Waves
A series of troughs and ridges on quasi-horizontal surfaces in the major belt of upper tropospheric westerlies. The waves are thousands of kilometers long and have significant latitudinal amplitude.

ROSSBY WAVES - long waves that form in air or water that flows almost parallel to the equator, which results form the effect of the earth's rotation.
Rossby waves Series of long-wavelength troughs and ridges that characterize the planetary-scale westerlies as they encircle the globe; also called long waves.

Rossby waves are generated by atmospheric forcing from winds and buoyancy effects from solar heating and are the principal means by which localised climatic effects drive the global response of the ocean.
In meteorology, this applies to atmospheric waves, such as long waves, short waves, Rossby waves, and cyclonic waves. In oceanography, this applies to waves generated by mechanical means, such as currents, turbidity, and the wind.
shortwave troughA relatively small-scale trough that is superimposed on and propagates through the longer wavelength Rossby waves.single-column modeling (SCM)An approach to the development and testing of cloud formation and parameterizations.
Rossby Waves:Discovered in the late 1930's by: Carl G. Rossby: a Swidish-American Meteorologist for whom they are named. Rossby Waves occur well above the friction level. They are steering currents and are at the 500 mb 18,000 feet level and higher.
This radius is important for determining the phase speed and wavelength of baroclinic waves (Rossby waves) in the general circulation. An alternative definition for internal Rossby radius of deformation is ...
These waves are within the province of both the general circulation and synoptic meteorology, but the terminology should distinguish this scale from that of the migratory high and low pressure systems of the lower troposphere. Rossby waves and other ...
Large ocean currents such as the Gulf Stream often meander like a river without a bank. Similar phenomina occurs with the jet stream creating a long wave trough or "dip" in the wind flow. These are all examples of rossby waves.
