Rossby parameter
The Rossby parameter is a number used in geophysics and meteorology which arises due to the meridional variation of the Coriolis force caused by the spherical shape of the Earth. It is important in the generation of Rossby waves. The Rossby parameter is given by
where is the Coriolis parameter, is the latitude, is the angular speed of the Earth's rotation, and is the mean radius of the Earth. Although both involve Coriolis effects, the Rossby parameter describes the variation of the effects with latitude, and should not be confused with the Rossby number.
