Devils and hairpins in the atmospheric surface layerSteve OncleyIn-Situ Sensing FacilityEarth Observing Laboratory
Vorticies 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 vorticies likely are dust devils, though no visual observations are available to confirm this. At night, this array appears to have made the first field observations of hairpin vorticies. This talk will describe the structure and dynamics of several types of vorticies and relate them to other vortex investigations, including tornadoes and hurricanes.
