WebbQueney's waves are dependent partly on the stability and partly on geostrophic forces, and the order of the wavelength is several hundred km. Scorer, in his treatment, deals with smaller-scale phenomena, so enabling geostrophic forces to be neglected, and provides for variations of stability and wind shear in the vertical. Webb1 apr. 2015 · Leaky trapped mountain lee waves are investigated by examining the structure of individual linear modes in multilayer atmospheres. When the static stability and cross-mountain wind speed are constant in the topmost unbounded layer, modes that decay exponentially downstream also grow exponentially with height.
