Abstract: The most widely used spectral models with the transform method are the dealiased spectral models in which the dealiased technique is used in the discrete Fourier transform according to the 3/2 rule. From the viewpoint of ...

Abstract: In the context of operational numerical weather prediction, using actual data as the initial conditions, aliased spectral models are compared with dealiased spectral models (operational European Centre for Medium-Range ...

Abstract: A coupled atmosphere-ocean primitive equation model is developed. It is a free-dimensional general circulation model, with two layers in the atmosphere and two layers in the ocean and includes solar radiation, longwave ...

Abstract: Commonly used horizontal diffusion and wavenumber truncation dealiasing methods in spectral models are verified using the National Center for Atmospheric Research Community Climate Model version 3. For the same horizontal ...
