We introduce a new high-resolution model that couples the atmosphere and ocean to better simulate extreme weather events. It combines the Geophysical Fluid Dynamics Laboratory (GFDL) advanced atmospheric and ocean models with a powerful coupling system that enables robust and efficient two-way interactions. Simulations show that the model accurately captures hurricane behavior and its impact on the ocean. It also runs efficiently on supercomputers. This model represents a key step toward improving extreme weather forecasts.
