Hi All, If I read correctly it appears that a NOAA is upgrading their NWP system in the near future, replacing the GFS with the FV3. What are peoples thoughts/hopes etc.
The link below will get you there.

Interesting. I don't know a lot about climate models but I have done a lot with water flow dynamic models.
I have seen the water modelling (hydraulics) industry over the last 30 years attempt finite element modelling (not good for flow over land), was well established in finite difference modelling, and recently trend towards finite volume modelling (FV). In that field that I am familiar with FV modelling is proving to be more stable for modelling rapidly changing flow, and is computationally more efficient.
So that NOAA move to FV could prove interesting... that said I would think there is no silver bullet for any modelling. Always improving is the right direction..
Models are for estimating and gauges are for knowledge.
