Abstract

The Oklahoma State University Themis Weather Phenomena Project sampled severe storm sferics in the vicinity of central Oklahoma and the Black Hills of South Dakota, as well as warm cumulus electrostatic fields in the Brownsville, Texas area. Data analysis has shown continued association of increased sferics with increasing severity of a storm. However, discrete storm events such as a tornado or hail do not consistently correlate with enhanced sferics in the VLF. Storm impulse periods are apparent from a sferic-rate power density spectral analysis performed on both airborne and ground based data. A cumulus, charge-density structure, model has been devised and a field-mill data reduction model is not being developed. (Author)
