Cameron Beccario (of earth.nullschool.net fame) recently shared an example of how detailed the new NOAA weather forecasting model is compared to the old version. In short, it’s much more detailed!

These wind field images are one forecast step (3 hours) apart, straddling the moment when FV3 was put into production.https://t.co/rWhdwqFt63https://t.co/3H5SosE0ifhttps://t.co/IxI4MLuM0r pic.twitter.com/QLVgSJoPfd
