Information
  • The eight NOAA MLWP systems: Aurora, FourCastNet, GraphCast and Pangu-Weather, each run twice — once from the ECMWF IFS analysis and once from the NOAA GFS analysis — so the top row of MODEL is the IFS initialization and the bottom row the GFS one. MODEL switches system and keeps the region, map and hour, which is the comparison this page is for: the same map, the same hour, a different model or a different analysis. 41 hours to day 10, 6-hourly, 00Z and 12Z. GraphCast is the only one of the eight NOAA writes precipitation for, so Total Precip is on it alone. The newest cycle fills in as it is drawn; this page picks up new hours by itself.
  • ALL 8 SYSTEMS shows the same map, area and hour on all eight at once: two columns, the IFS initialization then the GFS one, by four rows, a model each. So a row is one model from two analyses and a column is one analysis across the four models. Click a pane to open that system on its own. Only GraphCast has Total Precip, so the other six panes say so rather than go blank.
  • LAGGED (6 RUNS) shows the current run beside the five before it, all valid at the same time: how the forecast for that moment has changed run to run.
  • SAVE LOOP makes an MP4 or GIF of what you are looking at, for all the frames or just a range, in your browser; SAVE IMAGE saves the map on screen, or the six lagged runs on one PNG. Nothing is uploaded.
