Ekman layer

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.
