John P. Finley: Tornado Forecasting
(2017-08)
John P. Finley wrote the first book in English devoted to tornadoes. As a member of the US Army Signal Service, Finley's job was weather forecasting. By the 1880s Finley was widely recognized in the military as a tornado ...
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 ...
Radio-frequency emissions from runaway electron avalanche models compared with intense, transient radio-frequency signals associated with thunderstorms.
(2002)
The results of a one-dimensional model of a runaway electron avalanche, initiated by a high-energy cosmic ray secondary electron, in a thunderstorm electric field are presented. The time-evolution of the electron densities, ...
The structure and circulation of the atmosphere of Venus /
(The University of Oklahoma., 1971)
Computing Hydrogen Ion Survival Probability: Academy Student, Graduate Student, and Faculty Experiences
(2015-09-23)
This presentation covers the experiences of a Missouri Academy student, a Graduate Directed Project team, and Computer Science and Physics Faculty at Northwest Missouri State University in data management, computational ...
A diagnostic study of cyclogenesis in the lee of the Alps.
(1981)
Evaluation of energy transformations show that mean kinetic energy^within the volume (K), is converted to perturbation kinetic energy (K'), (' )^during the orographic phase. Mean available potential energy (A), is(' ...
3DVAR and cloud analysis with WSR-88D Level-II data for the prediction of tornadic thunderstorms.
(2005)
Doppler weather radar observations play a key role in initializing convective storms within storm-scale numerical weather prediction (NWP) models. The radial velocity and reflectivity are the two main parameters measured ...
Numerical simulations of cyclic storm behavior: Mesocyclogenesis and tornadogenesis.
(2003)
Building upon previous work that examined the dynamics and model sensitivity of cyclic mesocyclogenesis, this study uses idealized numerical simulations to investigate the cyclic redevelopment of vertical vortices in ...
Observations of x-rays produced by strong electric fields in thunderstorms.
(1997)
A balloon-borne x-ray spectrometer was developed to fly on free balloons into thunderstorms in order to test hypotheses that strong electric-fields could accelerate cosmic-ray secondary electrons and produce bremsstrahlung ...
