Cloud-to-Ground Lightning in Linear Mesoscale Convective Systems
Recently, three distinct archetypes for midlatitude linear mesoscale convective systems (MCSs) have been identified: those comprising convective lines with trailing stratiform precipitation (TS), leading stratiform precipitation (LS), and parallel stratiform precipitation (PS). While cloud-to-ground (CG) lightning in TS MCSs has received a great deal of study in recent years, linear MCSs exhibi...
متن کاملPositive and Negative Cloud-to Ground Lightning*
Positive cloud-to ground lightning (+ CGL) occurs in a minor fraction of all thunderstorms [1]. We propose that the microscopic mechanism is the same as in the more common negative CGL, whereas the different polarity is due to the macroscopic cloud dynamics [2]. The origin of collisional charging involves three stages in the basic process [3]. In the first stage kinetic roughening of the surfac...
متن کاملCloud-to-ground Lightning and Urban Areas
The effect of small urban areas on cloud-to-ground (CG) lightning activity is analysed for Spain. The results shown that the CG-flash number is enhanced within and downwind the most of towns considered and that large population and higher SO2 concentration contribute to the increase of the number of CG-flashes. INTRODUCTION AND DATA Several studies have reported that large cities of the USA are...
متن کاملX-ray bursts associated with leader steps in cloud-to-ground lightning
[1] X-ray and electric field measurements were made during five nearby negative natural lightning strikes in north central Florida during the summer of 2004. The observed X-ray emission typically was detected 1 ms before the first return stroke, during the stepped-leader phase, and had energies extending up to a few hundred keV. The X rays were produced in discrete, intense bursts emitted in co...
متن کاملElectric Field Pulse Bursts in Cloud-to-ground Lightning Discharges
Regular bursts of electric field radiation pulses produced by three multiple-stroke cloud-to-ground discharges recorded in 1991 at the NASA Kennedy Space Center are analyzed. The bursts are similar in the number of pulses per burst and inter-pulse intervals to the “multiple burst” component (so-called component H) of the standard lightning environment for the design and testing of aerospace veh...
