This is terrific on the meteociel site.
It's essentially the 20 ensembles that are put in rank order to highlight which of those are the most severe - in this case, 10m wind speed (km/hr - bleurgh!) in London: http://www.meteociel.fr/modeles/gefs...de=11&s ort=1 Essentially shows for each time, the ranked windspeeds across the ensembles. It shows very nicely on the 8th and 10th how there appears to be potential for quite strong sustained winds in a number of the ensemble members. Would be nice to include the control and operational numbers on this to see where they sit in the grand scheme of things but I thought this was a great way to show the data. The base page is he http://www.meteociel.fr/modeles/gefs...arte=1&table=1 From which you can choose your location of interest. One of the ensemble members has a 132 km/hr mean in western Ireland... http://www.meteociel.fr/modeles/gefs...mode=11&sort=1 Richard |

It's a most illuminating form of visualisation of the data. Careful scrutiny of it emphasises how futile it is to look at only a single model run (e.g. the operational run) for times as short as greater than about 48 hours ahead (at least looking at today's 1200z data). Fascinating stuff. -- Norman Lynagh Tideswell, Derbyshire 303m a.s.l. http://peakdistrictweather.org |

Fascinating stuff. Phew! I thought I might be talking to myself here. A lot of my job is to do with visualisation of data into simple format so this is really up my strasse. This really nails it. It's also great to see they've included so many other variables there too. Richard |

WeatherOnline are very receptive to suggestions on their website. I might suggest they do similar to Meteociel !! Richard |

(Probably by me!) However the original data in this thread originated from Meteociel. The MetO have a lot of exciting ensemble presentations including entropy, clustering etc. Sadly it is all for internal use, as is their excellent ensemble system MOGREPS.
