American model outperforming European in hurricane forecasts
It's time we give credit where it's due. The GFS American computer model is consistently doing better than its European counterpart in predicting the path of tropical storms.
This is huge news because for many years, the ECMWF model (European Centre for Medium-Range Weather Forecasts), typically referred to as the 'Euro' model, would consistently beat the GFS American model.
The GFS model underwent a massive overhaul that was years in the making. Technically, it's now the GFS-FV3, but everyone still calls it the 'GFS.' Using new supercomputers and a new dynamic core, the GFS now has a higher level of accuracy. This major overhaul went into effect in 2019, with upgrades thereafter into 2020.
Computer modeling isn't simple and can take years of collaboration between government, university and international scientists to make improvements and corrections. I learned this firsthand when I started my career at the National Weather Service headquarters before getting into the broadcast side of the business. I have a lot of respect for the scientists in this field that keep moving us forward in weather prediction.
