Spherical Harmonics and Helmholtz Decomposition in Atmospheric Modeling
Skyborn When dealing with global circulation, a ghostly problem always haunts us—the Pole Problem. On the latitude-longitude grid, all meridians converge at the poles, leading to severe distortion of grid cells, which not only brings great trouble to calculations (CFL condition), but may also introduce unrealistic errors. Visualization of the total derivative of velocity near … Read more
