Traditional or Reversed Funnel Shape in a Tornado-Like Vortex

Abstract

Extended Abstract In this work we study numerically the development of traditional and reversed funnel-shaped vortices in a rotating cylinder in the presence of horizontal thermal gradients at both, bottom and top, which are heated and cooled respectively. Field observations show the formation of traditional funnel-shaped and reversed funnel-shaped vortices in tornadogenesis. It is questionless the relevance of horizontal and vertical thermal gradients on the formation and evolution of those and other atmospheric vortices. Studies show the development of bottom-up vortices when exists a horizontal temperature gradient at the bottom [1,2], and the situation of a cold pool aloft is found in the context of cold air funnels and tornadoes [3]. in configurations localized
