Devils and hairpins in the atmospheric surface layer

Steve Oncley

In-Situ Sensing Facility

Earth Observing Laboratory

Vortecies in the atmospheric surface layer passing through a fixed array of 31 turbulence sensors have created a data set with unprecedented resolution of their characteristics and dynamics.  During the day, these vortecies likely are dust devils, though no visual observationsare available to confirm this.  At night, this array appears to have made the first fieldobservations of hairpin vortecies.  This talk will describe the structure and dynamics of several types of vortecies and relate them to other vortex investigations, including tornadoes and hurricanes.
