RISA Geographic Information Systems–Based Analysis of Supercells across Oklahoma from 1994 to 2003
Publisher: American Meteorological Society
Abstract: Oklahoma is a region that is well known for its high frequency of severe thunderstorms, which vary in activity, mode, and coverage. In particular, this region experiences a significant number of highly organized supercell ...
Drought and Pluvial Dipole Events within the Great Plains of the United States
Publisher: American Meteorological Society
Abstract: he purpose of this study was to quantify dipole events (a drought year followed by a pluvial year) for various spatial scales including the nine Oklahoma climate divisions and the author-defined regions of the U.S. Southern ...
Improved Installation Procedures for Deep-Layer Soil Moisture Measurements
Publisher: American Meteorological Society
Abstract: The Oklahoma Mesonet, an automated network of 115 meteorological observing stations, includes soil moisture monitoring devices at 60 locations. The Campbell Scientific model 229-L matric potential (water potential) sensor ...
Significant Inversions and Rapid In Situ Cooling at a Well-Sited Oklahoma Mesonet Station
Publisher: American Meteorological Society
Abstract: The El Reno Oklahoma Mesonet (ELRE) site is one of a few Oklahoma Mesonet sites that has measured inversions of 10°C or greater between 1.5 and 9 m. Historical analyses revealed that strong inversions at ELRE have occurred ...
