Abstract

Idealized numerical simulations of the bora-type flow have been performed. The intention was to find what causes the pulsations in the developed windstorm state to disappear. Four different incident vertical profiles were used and the results showed that the main effect originates from the low-level positive shear, and the uppertropospheric jet stream acts as a secondary effect.

Keywords

quasi-periodic pulsations; wave breaking; wind shear; numerical modeling
