4. Discussions and Conclusions

Numerical experiments were carried out using a high-resolution spectral model on 2-dimensional decaying turbulence on a rotating sphere. We examined what pattern appears finally and identified the conditions that must be satisfied for each type of pattern to appear, varying in a stepwise manner the experimental parameters of central wavenumber, which defines the initial energy spectrum, and rotational angular velocity of the sphere. The following conclusions were reached.
