Alta-Deer Valley (Sheraton Salt Lake City Hotel)
The Southern Brazilian region is specially affected by extreme weather events, very often intense wind gusts coming from deep convection may develop it self as a microburst producing winds higher than 100km/h. In order to understand the physical and dynamical process evolved in this phenomena, a static and isolated microburst is produced trough a Large Eddy Simulation. A quantitative analysis of propagation an maintenance of the microburst vortex ring is performed in order to understand its evolution. To this end, an analysis of the number of Richardson, for each time-frame, is made. Thus, it is possible to analyze how the stability of the environment influences the maintenance and propagation of the vortex.
