Yeah - using english terms I actually mixed it up, what I meant was the wind gradient and not the ground effect (the ground effect beeing the "floatiness" close to the ground produced by the pillow of over pressurized air under the wing and the wind gradient beeing the fact that the wind is a lot weaker close to the ground due to turbulence). The wind gradient is always present in wind and can be quite nasty in strong wind for rookie pilots coming in to slow. Suddenly you can lose 20-30 km/h of air speed while the ground speed remains the same. In this case it was extreme
