One of the FV3-based models that is being developed within NOAA is the Hurricane Analysis and Forecast System (HAFS). I have been working with others here at AOML and colleagues at NOAA EMC, GFDL, and other university labs to develop and evaluate HAFS. See some key developments below.
Here is an animation of all the 2020 forecasts from the global-nested HAFS system we ran in real-time at AOML/HRD.
