PROWAM model

PROWAM is the wave model used for projections of changes in offshore waves in UKCP09.

In detail

The PROWAM model is a modified version of the WAM cycle-4 3rd generation wave model, which is a spectral (phase-averaged) wave model. It includes wave generation by wind, non-linear wave-wave interactions and dissipation processes including white-capping and bottom friction.

PROWAM is a version of WAM developed to run on higher spatial resolution than the standard WAM model and also includes some extra shallow-water processes.
