An application of stochastic forecasting to monthly averaged 700 mb heights.
(1981)
One month dependent and independent forecasts of the standardized height anomalies are made and compared to similar forecasts made climatologically. The multivariate autoregressive model is found to perform better on the ...
Electrification and lightning in simulated supercell and non-supercell thunderstorms.
(2000)
Three parameterizations of a noninductive graupel-ice mechanism and various strengths of inductive graupel-droplet charging were tested. For a given storm type, the charge distribution and lightning produced by the different ...
The Role of Surface Drag in Supercell Tornadogenesis and Mesocyclogenesis: Studies Based on Idealized Numerical Simulations
(2017-05)
Idealized numerical simulations of supercell thunderstorms have been employed for several decades to study tornadogenesis, providing valuable insights that have helped shape our current understanding of the process. Until ...
Optical observations of lightning by the FORTE satellite: Terrestrial ground truth and implications for the interpretation of Jovian lightning data.
(2001)
Lightning and storm electrification have been studied from many different viewpoints and with many different instruments. The myriad of viewpoints and instruments often see the results or effects of different processes ...
The impact of Oklahoma's winter wheat belt on the mesoscale environment.
(2003)
The research documented in this manuscript demonstrates that Oklahoma's winter wheat belt has a significant impact on the near-surface, mesoscale environment during growth and after harvest. Differences in near-surface ...
Twist and Shout!
(2013)
Surface thermodynamic characteristics of hook echoes and rear-flank downdrafts, with implications for tornado genesis and maintenance.
(2000)
Since its first documentation in 1953, the "hook echo" has been perhaps the best-recognized radar feature of supercell storms. Hook echoes have been associated with a region of subsiding air to the rear of both tornadic ...
