The Multi-Year Reanalysis of Remotely Sensed Storms is a joint venture between the National Severe Storms Laboratory and National Climatic Data Center to reprocess radar data for the entire country during the lifespan of WSR-88D. This dataset provides several data mining opportunities through the use of the Warning Decision Support System Integrated Information (WDSS-II) software. This presentation summarizes a methodology for the automated retrieval of azimuthal shear utilizing WDSS-II tools. Results are presented for 443 tornado events that occurred in 2010 and 2011. Potential applications of the azimuthal shear values, areas of future research, and possible improvements to the methodology will also be discussed.

For accommodations based on disability, or more details, please call 325-6561. All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.

The University of Oklahoma is a smoke-free / tobacco-free campus.
