trumpetsailor Posted April 27, 2007 Share Posted April 27, 2007 Hi! 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? Thanks! Quote Link to comment Share on other sites More sharing options...

Gary_Yngve Posted April 27, 2007 Share Posted April 27, 2007 The MM5 models can help you look at specific cloud layers. http://www.atmos.washington.edu/mm5rt/ Quote Link to comment Share on other sites More sharing options...
trumpetsailor Posted April 28, 2007 Author Share Posted April 28, 2007 Weather is hard. Aye, but that doesn't tend to preclude folks from prognosticating about it. Quote Link to comment Share on other sites More sharing options...
jmace Posted April 30, 2007 Share Posted April 30, 2007 Aviation forecasts dont tend to look very far out... what would be best for you is a forecasted sounding. Do you know how to read a sounding? Forecasted Sounding Whats this free air term you use..? Quote Link to comment Share on other sites More sharing options...
