DOI: 10.1016/j.jweia.2019.02.010
Abstract: Abstract Wandering of tornado-like vortices consists in random oscillations of the vortex core from its time-averaged position, which complicates efforts to characterize vortex characteristics. A procedure is then necessary to retrieve characteristics of tornado-like vortices… read more here.
