The maps also indicate two components of wind direction: U-wind represents the east-west component of wind and V-wind represents The speed of sound is not a constant, but depends on altitude (or actually the temperature at that altitude). miles per hour (mph) knots (kt) meters per second (m/s) kilometers per hour (km/h) feet per second (ft/s) 300 mb -> 30,000 feet 250 mb -> 34,000 feet 200 mb -> 38,600 feet 150 mb -> 44,300 feet If you don't know the altitude of the plane you are observing, then ideally use the 250mb/34000feet observation. Since wind speeds tend to be pretty variable over time, I assume this would give the most accurate wind speed for the most important flight regime. For the purposes of this model, the wind speed in the first 1000 or so feet is the most important, since this is when the rocket is most vulnerable to the destabilizing effects of the wind, but it would of course also be great to model wind during the rest of the flight as accurately as possible. That's because the speed relative to the air is closer to 600 mph since the air moving along with the jet stream was in the same direction as the plane (west-to-east). Wind Load vs. Wind Speed - Engineering ToolBox Very low wind speeds do not receive a I've spent a lot of time looking into this and it looks like data like this exists, but I haven't quite found it in a format I understand yet. Hub heights of modern 600 to 1,500 kW wind turbines are usually 40 to 80 metres, however. Therefore, do not expect V ector functions are used to average wind direction and can be used to compute a type.
