Cyclostrophic winds
WebBy definition, a cyclostrophic wind exists when the pressure gradient force is balanced by the centrifugal force alone. This exact situation rarely exists, but is so nearly reached in some situations that the small Coriolis effect … fetch, area of ocean or lake surface over which the wind blows in an essentially constant direction, thus generating waves. The term also is used as a synonym for fetch length, which is the horizontal distance over which … See more

WebCyclostrophic winds show satisfactory agreement with the cloud-tracked winds derived from the Venus Monitoring Camera (VMC/VEx) UV images, although a disagreement is observed at the equator and near the pole due to the breakdown of the cyclostrophic approximation. From zonal thermal winds the Richardson number has been evaluated. WebCyclostrophic flow is a fairly common flow in the atmosphere. This balance involves two forces in the n equation of motion, those being the following: The centrifugal force: The pressure gradient force: With the …

WebFigure 1 illustrates the role of B in shaping the wind profile at fixed latitude,Vmax and Rmax.AsB increases, the strong winds become increasingly localized near the radius of maximum winds. For larger B, the wind drops off more abruptly both outside and inside the radius of maximum wind, and a larger area of nearly calm wind occupies the ... greek festival 2022 myrtle beach scWebAfter tailoring the model for TC applications, a gradient wind is computed from a cyclostrophic wind formulated in terms of the cyclostrophic Rossby number.
