That's why when UK's Met Office upgrades to a 17 petaflop computer system (made by the same company that made a 5 petaflop computer system for the NWS), it will totally blow out whatever else the rest of Europe or the US will us, even though their computer system won't strictly be used for daily forecasts, and our supercrays are used for daily forecasting only. COAMPS: COAMPS-TC regional model, initialized using GFS data However, NHC’s genesis forecasts were too conservative at the lower and upper ends of the distribution. It stuck with me over the years and I eventually decided to pick a college that would allow me to study a little weather. The upgraded GFS became operational on Wednesday morning at 12z, or 7:00 AM EST, meaning that forecasters at the National Weather Service officially began using the upgrade in their forecasting process. MASTERS CANT HIT ON YOU GUYS ANYMORE, THIS IS THE YEAR OF THE GARBAGE STORMS, SO FAR ALL BUT 2 HAVE BEEN GARBAGE WAISTED NAME STORMS, So you have a habit of talking to yourself…maybe get some professional help friend, I THINK YOU AND MASTERS HAVE BOTH SEEN A FEW UP CLOSE, © 2020 Yale Climate Connections | Site Host/Developer WebFirst, Category 4 Hurricane Eta expected to dump catastrophic rains in Central America, ‘Extremely dangerous’ Hurricane Eta may cause catastrophe in Central America, Super Typhoon Goni slams into Philippines as strongest landfalling tropical cyclone on record, Super Typhoon Goni intensifies to category 5 in the Pacific, becoming strongest storm of 2020, 2019 National Hurricane Center Forecast Verification Report, may still be useful for tracking long-term or seasonal shifts, Experimental Tropical Cyclone Genesis Guidance page, https://disqus.com/home/discussion/wund/weather_underground_2993/newest/. Ian Livingston, a forecaster for the Washington Post's Capital Weather Gang, noted on Twitter a few days ago that the upgraded model "ended up not too bad" when it came to the fast-moving clipper systems that dumped snow on the Washington D.C. area. The upgrade is a great tool that's already had some real-world impact in its improved accuracy. Navy: Navy Global Environmental Model (NAVGEM). Animate, compare, export and create customised GIFs. New system: It may rain or be sunny or it may snow. Official NHC intensity forecast errors in the Atlantic in 2019 were similar to the five-year average for 12-hour, one-day, two-day, and three-day forecasts, but above the mean for four-day forecasts, and well above the mean for five-day forecasts. The old GFS model ran at a horizontal resolution of 27 kilometers (16 miles), meaning that there were 27 kilometers of horizontal distance between each of the model's forecast grid points.

[Images via Tropical Tidbits and WeatherBELL]. A new version of the GFS ensemble model (called GEFSv12) is in the experimental phase, and is the first update to GEFS in five years. It was the model that correctly predicted the blizzard of '78 two days out- an amazing feat at the time. Taking over was the Nested Grid Model (NGM), which was essentially an improvement of the LFM.It was a wonder in the world of weather at the time, and I was getting into the forecasting just as it arrived. (An open-access paper published in July in Geophysical Research Letters analyzed the data gap and its impact on global model performance this past spring.). For intensity, the official NHC forecast and various models did not show a lot of separation, though the LGEM model performed noticeably worse than the other top models.
