Description
We present a new forecast model for rotating shallow water equations in spherical geometry. The model is a horizontal component of numerical weather prediction system currently under development in theoretical meteorology group at the University of Hamburg. In contrast to the majority of spectral schemes, which employ spherical harmonics, our model uses Hough functions as the expansion basis. This represents the motion as a system of interacting waves that have a clear geophysical interpretation.
In the talk we discuss advantages and disadvantages of the model, present the convergence rates on analytical solutions, and model's performance on geophysically important complex flows.
