Abstract: Locations of positive and negative cloud-to-ground lightning flashes can be distinctly regionalized within some mesoscale storm systems. This phenomenon, observed as a bipolar pattern, was documented and analyzed for the ...

Abstract: Observations of summertime thunderstorms indicate that positive polarity cloud-to-ground lightning activity can occur with rates as high as 67 flashes in 5 min and spatial densities up to 0.60 flashes per square kilometer ...

Abstract: Meteorological radiosondes that use navigation systems to determine winds (and horizontal location) can be susceptible to data loss in thunderstorm environments. This paper reports on tests of a radiosonde that uses the ...

Abstract: Five soundings of the electric field and thermodynamic properties were made in a mesoscale convective system (MCS) that occurred in Oklahoma and Texas on 2?3 June 1991. Airborne Doppler radar data were obtained from three ...

Abstract: The lightning data that are recorded with a three-dimensional lightning mapping array (LMA) are compared with data from an electric field change sensor (in this case a flat-plate antenna operated both as a ?slow? and a ...
