The University of Miami Wave Model (UMWM) is a spectral ocean wave model for prediction of wave spectra and wind stress. It solves the wave energy balance equation and predicts full wavenumber-directional spectra, as well as integrated wave quantities such as significant wave height, dominant and mean period, wavelength and direction, Stokes drift velocities etc.

UMWM is applicable on wide range of spatial and temporal scales, from small lakes to global applications. It resolves most physical processes that govern the evolution of the wave energy spectrum.

UMWM uses Unidata's NetCDF library for input and output, which is a commonly used data standard in the geophysical sciences. Interfaces to NetCDF data files are available from many analysis software packages (MATLAB, IDL, GrADS etc.) as well as programming languages (Fortran, C/C++, Java, Python etc.).

UMWM can be run on a personal computer for smaller applications, as well as on parallel high-performance computing clusters for research and operational wave forecasting.

UMWM follows the Earth System Modeling Framework (ESMF) standard which makes it convenient for coupling with atmosphere and ocean circulation models.
