FV3 will replace the GFS. Not so much that it is a whole new weather model but rather the computing and physics of the GFS will change to the new system. Better data assimilation allows the new dynamic core to have better skill scores, trying to close the gap on the Euro. Each year essentially the GFS gets improvements in calculating formulas and computing power but this will be the first nearly complete change of the core dynamics of how the model is run. It's like gutting a car for a new and better engine.
Thanks Ntxw! I hope it is an improvement over the GFS.
Well the FV3 did a very good job with the last artic blast we had a couple weeks ago. It was the first model to latch onto the cold.
