How to determine wind speed
WebOct 19, 2024 · The wind typically veers (rotates clockwise) with altitude, so if you see a lake or someone burning something that suggests the wind is blowing on it from the west, with signs that suggest it's blowing at, say, 10kts, you can expect it to be more northwesterly the higher you go, and faster. WebDec 6, 2015 · Wind speed and direction can be calculated by subtracting the true air speed vector from the ground speed vector. You will notice that there are a lot of possible sources of error in this procedure. All instruments involved have their own bias and scaling error.
