Summary

A theoretical approach is presented which treats flow over an obstacle under neutral or slightly unstable conditions in a two-layer model, The upper layer is assumed to be stable, Cases are presented for different degrees of instability, different wind shear conditions. different boundary-layer depths, and different obstacle heights,

Zusammenfassung

Es wird ein theoretischer Ansatz vorgestellt, der die Strömung über ein Hindernis unter neutralen oder leicht labilen Bedingungen in einem Zweischichtenmodell behandelt, Die obere Schicht wird als stabil angenommen, Fälle verschieden starker Labilität, verschiedener Windscherung, verschiedener Grenzschichthöhen und verschiedener Höhen des Hindernisses werden präsentiert,
