 Poster: A snowHead
|
I started to knock something up, purely for myself, then thought I may widen it out.
So would anyone else find it useful?
If so and if you know the magic GFS co-ordinates for a resort, please reply here, and I'll collate them all up and update the page....

kitenski, Just to make this clear, on your site you say that the last 12 runs of the gfs are shown on the ensemble graph. I hope what you mean by this is that the 12 runs from the last gfs ensembles run are shown, not that the last twelve runs (ie spanning over the last three days) are shown side by side, which is not the case.

Well, the person's real but it's just a made up name, see?

Greg, can I suggest changing:
The graph that is displayed shows precipitation and the 850mb temperature forecast includung the last dozen GFS forecasts and an annual average. The average data is shown by the red line, the current forecast by the blue line, and the average of the last dozen forecasts by the white line. When all the different forecasts are in close alignment you can infer that there is some certainty in the GFS forecast data, but if the lines are all over the place it is difficult to say with any confidence what the weather will do.
to:
The graph that is displayed shows precipitation (in mm per 6 hour period, note that 1 mm of rain roughly corresponds to 1cm snow) and the 850 mb temperature forecast (usually this corresponds to somewhere around 1500m altitude). The average for the time of year (over the period 1971-2000) is shown by the red line while the current forecast from the model is shown by the green line. The thin coloured lines are obtained by running the model with the input data slightly tweaked within its statistical accuracy. When the lines are all over the place you can infer that the model has no idea what's going to happen.
