“Metocean” is a combination of the words “meteorological” and “oceanographic.” Metocean refers to the interaction of the atmosphere and the ocean, which influence each other and have profound impacts from global climate to coastal weather. These two massive bodies of thermodynamic, swirling fluids exchange moisture, heat, and energy at all scales, from planetary to droplet. One cannot be accurately described without taking into account the influence of the other. The term “metocean” is used to capture that interaction and recognition that both atmosphere and ocean are included. This metocean concept is why Fathom Science uses coupled numerical modeling, which links atmospheric models with ocean models.
