Tornado-like vortexgenesis in a simplified numerical model

A novel approach to the modeling of tornado-like vortexgenesis has been developed and is used to articulate the sequence of events that leads to tornadogenesis. The "pseudostorm' is an idealized thunderstorm representation and emulates the storm-relative flow, into an updraft, of the horizontal streamwise vorticity that is baroclinically generated in cool arid outflow. By not explicitly simulating the morphology of a tornadic thunderstorm, but instead concentrating on the development of low-level rotation and tornado-scale vortices, the authors are able to transcend many of the experimental limitations encountered by cloud modelers. -from Authors
