Neil, your guess makes sense, perhaps the image in the “Earth-App” is interpolated from very distant values.
And if a cyclone with high windspeeds passes by at some distance, these speeds are shown as actual speeds in the whole area.
I am living in the near of Cologne and the North Sea is about 250Km distant. Perhaps NOAA observed high windspeeds over the sea effect high windspeed indication on the display, because they are only calculated out of some distant obervations.
Since I am not using the Outernet for my personal weather forecast, this is not dramatic for me and of course I am familiar with the different sources of weather observation (METAR, APRS, etc). I opened this thread to ask for other users observations, because I suspected a fault in the system, as for instance shifted data or high-altitude windspeeds instead of ground-level.
Thank you for your remarks and all the best to you for the new year,
