WebFeb 25, 2024 · The real issue with wind isn't the speed of the wind per se — it's the component of the wind that's blowing across the runway in use. Planes like to take off into the wind, because it's the only thing in aviation that's free and provides lift. When air flows over the wings, flight happens, and the wind helps with that during take off. WebAt 2 metres, wind speed may be only 50-70% of these figures. The specifications are descriptions of likely observations on land or at sea, and the probable and maximum wave heights (in metres) are quoted for the open sea. The figure for sea state (on a scale from 0-9) is a shorthand way of describing the sea surface conditions to various users. ...

WebMay 13, 2024 · Wind Speed. For a reference point picked on the ground, the air moves relative to the reference point at the wind speed. Notice that the wind speed is a vector quantity and has both a magnitude and a direction. Direction is important. A 20 mph wind from the west is different from a 20 mph wind from the east. A hurricane is a giant, spiraling tropical storm that can pack wind speeds of over 257 kph (160 mph) and unleash more than 9 trillion liters (2.4 trillion gallons) of rain.
