Default SkySight Soaring Weather Forecasting

Sorry, should have specified US West was working. East has a blank for Saturday. May be just missing data in the in the current forecast 2:49pm EDT? Try US East again in a few hours.

We are actually experimenting with ECMWF as an initialisation source. If it provides measurable improvement we will utilise it for regions where it does so.


Wow, I thought ECMWF boundaries would cost arm and leg to use commercially. I bet it provides measurable improvement, it is the best model currently available and on different level than GFS. Now if someone would run ensemble of RASP using ECMWF ENS members as boundaries, we would get usable thermal forecasts for next week instead of 2 days...


We run the WRF model with EC data. It is noticeably better - there are many more levels and the horizontal resolution we get is at 0.1 degrees vs the 0.25 for the GFS/GDAS. In addition, the EC analyses and forecasts are generally a lot better.

PS. It isn't cheap.

Hi,
I didn't see this thread alive again earlier, but as Paul/Jim deduced the forecast completed on the next run.
As to ECMWF, we are still testing. It's not so clear cut that it performs better for short term soaring forecasts due to their output intervals and timing. Contact me offlist if you want to know more.
Cheers,
Matthew
