Convective Storms & NWP Seminar Series presents...
The dependence of QPF on the choice of microphysical parameterization for lake-effect snowstorms and other winter weather topics at NSSL
15 February 2013, 2:00 PM
National Weather Center, Room 5600
120 David L. Boren Blvd.
University of Oklahoma
The primary focus of this talk will be on a series of numerical model forecasts made of a lake-effect snow event. These forecasts examine how dependent QPF is on the choice of microphysical parameterization. Notable differences are observed in the amount and distribution of precipitation with some schemes having very narrow and heavy precipitation shields and others having a more diffuse pattern. Causes for these different patterns will be discussed as well as some limitations to validating QPF in the lake-effect snow environment. The talk will then segue into other winter weather topics the author is involved with at NSSL. These include the development of a new winter surface hydrometeor classification algorithm, some forays into blizzard potential forecasting, and theoretical aspects of orographic precipitation.
For accommodations based on disability, or more details, please contact the School of Meteorology at 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.
