About
WAVEWATCH IV TM (commonly abbreviated as WW4 TM) is a community wind wave modeling framework that includes the latest scientific advancements in the field of wind-wave modeling and dynamics. It is being developed as a software modernization project for WAVEWATCH III, and as such the next step in a nearly 4 decade journey of WAVEWATCH wind wave models. For a history of these models up to version III, see Tolman (2026).
