Analysis of the propagation and maintenance of vortices generated by a static and isolated microburst

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.
