Closures of the surface energy budget.
(2000)
Results outline appropriate procedures for limiting instrument and system error in measurement of the surface energy budget. A systematic error was identified from an examination of closure at ten OASIS sites, and a ...
Ensemble cloud model applications to forecasting thunderstorms.
(2000)
A cloud model ensemble forecasting approach is developed to create forecasts which describe the range and distribution of thunderstorm lifetimes that may be expected to occur on a particular day. Such forecasts are crucial ...
Tropical climate stability, Hadley circulation, and deep cumulus convection: Vital synergism on a wet planet.
(2000)
Important features of the proposed formulation for precipitating deep turbulent clouds include the ability to calculate precipitation efficiencies, a new postulation relating cumulus buoyancy to solar radiation, and 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 ...
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 ...
Clustering methodologies applied to short-term ensemble forecasting: An exercise in data mining.
(2000)
In ensemble forecasting system, the divergence of the ensemble members during evolution may lead to the identification of clusters of different sizes in the finale state. Based on the size of each cluster, probabilities ...
A pseudo-dual-Doppler analysis of cyclic tornadogenesis.
(2000)
The goals of this study were twofold. The first was to determine a pseudo-dual-Doppler wind synthesis method in Cartesian coordinates appropriate for the analysis of the ELDORA data. Unique aspects of this part of the study ...
