Some Spatial and Temporal Relationships between Lightning and Storm Structure and Evolution,
Abstract
We have used a number of systems to study relationships between lightning and other storm parameters. Instrumentation includes a system for locating cloud-to-ground lightning strike points, an acoustic lightning mapper and a VHF (30-80 MHz) lightning mapper to study the structure and location of lightning, and S-band radar to provide other storm data. Several characteristics of the reconstructed lightning have been relatively constant: (1) lightning structure is usually predominately horizontal; (2) lightning tends to occur preferrentially in certain altitude ranges that are only a few kilometers thick and above the 0deg C isotherm; (3) it tends to occur near, but not necessarily inside, cores of high reflectivity (approx. > or = 45 dBZ), and it often connects with regions of relatively weak reflectivity downstream from stronger reflectivity and updraft cores. Other relationships are also discussed. (Author)
