MASNUM Wave Model

Introduction

It is a third-generation Wave Model LAGFD-WAM developed in early 1990s by LAGFD (Laboratory of Geophysical Fluid Dynamics), FIO (First Institute of Oceanography) of SOA (State Oceanic Administration), China. Since the LAGFD became MASNUM (Key Lab of Marine Science and Numerical Modeling, SOA, China), this model is now referred as MASNUM wave model. This model was designed for the wave forecast and hindcast. In recent decades, in order to evaluate the wave-induced mixing in the upper ocean and the impact of surface waves on ocean-atmosphere fluxes, a global wave numerical model in spherical coordinates was developed. In the model, the wave energy spectrum balance equation and its complicated characteristic equations are derived in wave-number space. The breaking dissipation source function is adopted a theoretical result based on statistical study of breaking waves (Yuan et al, 1986). The characteristic inlaid method is applied to integrate the wave energy spectrum balance equation. The current version (V2.2) are arranged by module in Fortran-90 and its parallel scheme using MPI with the irregular rectangle partition methods.
