Summary

A two-layer model of the planetary boundary layer is suggested. In the surface layer the theoretically and experimentally well studied coefficient of turbulent exchange is used. Above the surface sublayer the equations of motion are approximately solved with a coefficient of turbulent exchange in an arbitrary but not quickly varying height function. By means of the resistance law the height of the surface sublayer is found.

Zusammenfassung

Es wird ein Zweischichtenmodell der planetaren Grenzschicht vorgeschlagen. In der bodennächsten Schicht wird der theoretisch und experimentell gut untersuchte turbulente Austauschkoeffizient verwendet. Oberhalb der bodennächsten Schicht werden die Bewegungsgleichungen näherungsweise mit einem turbulenten Austauschkoeffizienten gelöst, der einer willkürlich angenommenen, mit der Höhe jedoch nicht sehr rasch sich ändernden Funktion entspricht. Mit dem Widerstandsgesetz wird die Höhe der bodennächsten Schicht bestimmt.
