just returned from the canaries where windytv proficiently helped me to pick my bikeroutes, adapted to the prevailing wind conditions.

these winds change fast and seem unpredictable and although the connection between general weather and wind is somehow limited it seems clear to me that it must be hard to make any accurate predictions.

I used to be married to a military forecaster. It was always interesting to hear about how this stuff works, and it seems to me that "models not fitting reality" comprised at least 50% of their office drama. Forecasters have their own preference for models and "past experience" which leads them to very different conclusions. And climate change is making these models much less effective over time, adding even more excitement.

Do you know where to get archived numerical ECMWF/NAM/NEMS/GFS data? Not necessarily on a map.
