Lightning Flash Rate In The Lake Maracaibo, Venezuela Related To Sea Surface Temperatures And Tropospheric Air Flow, Deirdre Smith
Lightning Flash Rate In The Lake Maracaibo, Venezuela Related To Sea Surface Temperatures And Tropospheric Air Flow, Deirdre Smith
LSU Master's Theses
Northern Venezuela's Lower Maracaibo Basin (LMB) has the highest lightning flash rate (LFR) density in the world. The area receives approximately 200 flashes per km^2 annually. Local topography as well as local and global scale climate drivers have been shown to influence the frequency of the lightning storms, known as "Catatumbo Lightning". This research focuses on influences on LFR in the LMB by local and global sea surface temperatures and elements of local tropospheric air from 1996--2015. Sea surface temperature and tropospheric air data from the National Oceanic and Atmospheric Administration are used in Spearman rank correlations to determine relationships …
A Climatological Exploration Of Land Change And Land Use On Lightning Patterns Over Louisiana, Nicholas James Sokol
A Climatological Exploration Of Land Change And Land Use On Lightning Patterns Over Louisiana, Nicholas James Sokol
LSU Master's Theses
Lightning is one of the most impactful weather phenomena but yet little precise and accurate information is known about how its frequency is impacted climatologically by changes in land use/land cover (LULC). This is unfortunate because LULC changes occur ubiquitously as the human influence on the environment proceeds. This research uses NOAA’s gridded annual lightning data from the National Lightning Detection Network (NLDN), and LULC classification data from the NOAA coastal change analysis program (C-CAP) to analyze frequency changes in lightning across a swath of Louisiana, coastal Mississippi, and coastal east Texas over the years 1995–2011. Results suggest that urban …
