WebbThis is the vorticity equation in height coordinates (Martin 5.33). This equation states that the Lagrangian tendency (time rate of change following the flow) of the absolute … WebbFor an estimate, use the simplified version of (13.120), U = β / k2 = βλ2 / (2 π) 2, and recognize that 3,000 km represents the peak-to-valley distance or half of the Rossby wavelength. The numerical values then imply: where a mid-latitude value of β = 2 × 10 −11 m −1 s −1, has been used.
