The Ekman layer (after Vagn Walfrid Ekman ) is the main part of the atmospheric boundary layer.
It begins at the upper limit, named after Ludwig Prandtl Prandtl layer approximately 100 m and extends up to about 1000 m altitude, the upper limit of the atmospheric boundary layer. Thus, it can be considered as a lower half of the Peplosphäre. The Ekman layer is on the northern hemisphere by a wind shift to the right and marked only slight wind increase. Plotting the values measured in the different height levels of the Ekman layer wind direction and speed, so the top of the wind arrows describes the so-called Ekman spiral.
