Improved double Fourier series on a sphere and its application to a semi-implicit semi-Lagrangian shallow-water model
<p>One way to reduce the computational cost of a spectral model using spherical harmonics (SH) is to use double Fourier series (DFS) instead of SH. The transform method using SH usually requires <span class="inline-formula">O(<i>N</i><sup>3</sup>)</sp...
