Non-free air winds?

Recommended Posts


I've been watching the Rainier forecast and the Camp Muir weather data for a few days in an effort to discern the relationship between the free air wind speed prediction and the actual speed on the ground. It looks to me as though the normal error in forecasting will make this more difficult than I'd hoped. In your experiences, how have free air predictions compared with what you've observed on climbs?


Also, does anyone know of a forecasting source that might give some insight into the thickness of forecasted cloud layers? "Mostly Cloudy" for a forecast at Paradise isn't as useful as "Thick clouds 6000-9000'". Aviation Forecasts?
