Nettet1. nov. 1998 · Mountain-wave breaking can occur when the wind speed falls and⧹or the atmospheric stability increases, as both these factors compress the vertical wavelength of the waves (VanZandt and Fritts, 1989), thereby producing the turbulent layer found at the top of the region of mountain wave activity in Fig. 1. NettetThis lesson focuses on forecasting mountain wave turbulence. Its methodology relies on the spatial and temporal distribution of winds, stability, and clouds to forecast and verify mountain wave turbulence. Analyzed forecast products include NWP charts, cross sections and soundings, satellite imagery, RAOBs, ...
