Relating Total Lightning and Storm Microphysics to In-Cloud Convective Turbulence
Data from the NCAR Turbulence Detection Algorithm were compared with total lightning data measured by the Colorado Lightning Mapping Array and dual-polarimetric radar data from the Denver, Colorado and Cheyenne, Wyoming WSR-88Ds. This was done in order to determine possible temporal and spatial relationships of turbulence to electrical and microphysical storm properties. In several case studies of severe storms over Colorado, Wyoming, and Nebraska, it was observed that higher total lightning frequencies accompanied higher turbulence intensities. CIT often occurred prior to any lightning discharges. Likewise, lightning was located within the mixed phase region of a storm, while turbulence maxima often extended just above this region. Additionally, turbulence was observed within the storm after the last lightning strike. Results suggest lightning may be indicative of in-cloud CIT.
