WebApr 11, 2024 · The vortex structure on the shear layer moves downstream under the convection, and the unsteady oscillation of the shear layer finally scatters in the form of a sound wave. Second, compared with the deep buffeting state, the maximum SPL of the subsonic stall decreases by about 50 dB and the maximum SPL is located in the shear … WebA couple of aspects of shear within the cloud layer are critically important for thunderstorm forecasting. First, updrafts can be persistent (last longer) when deep-layer wind shear is …
