![]() ![]() Global and tropical total lightning began to be more extensively measured by satellites in the mid 90s. Total lightning (intracloud and cloud-to-ground) monitoring is a relatively new field of observation. Furthermore, the relationship between convective lightning production (thunderstorms) and temperature is even more complicated, being subjected to the cloud dynamics and microphysics. The relationship between temperature, humidity and convection is not linear and is strongly dependent on regional scale features, such as topography and land cover. ![]() The International Panel on Climate Change (IPCC) assessment report (IPCC, 2007) shows inconclusive answers on global rainfall trends and general agreement on a future drier climate with increased global warming. While global warming is regarded as a fact by many in the scientific community, its future impact remains a challenge to be determined and measured. Working collaboratively with our NWS partners, SPoRT is working to determine how best to integrate these future observations to improve both severe storm warnings and lightning safety.Ĭlimate Change and Tropical Total LightningĪlbrecht, R. SPoRT, in conjunction with NOAA s GOES-R Proving Ground, is working to prepare the end user community for the GLM era using the LMA observations as a demonstration tool. This is being addressed with the next generation geostationary satellite, GOES-R, which will boast the Geostationary Lightning Mapper (GLM). The LMAs have a short range of no more than 200 km. SPoRT and its partner NWS offices are working to develop visualizations and applications to better utilize these data. Just as importantly, the observed intra-cloud flashes often precede the first cloud-to-ground strike by a few minutes. With total lightning observations, NWS offices can enhance their situational awareness and improve severe weather warnings. Combined, these observations are called total lightning. Much of that work has focused on the LMA s ability to detect intra-cloud lightning in addition to cloud-to-ground lightning strikes. SPoRT has been collaborating with the Huntsville National Weather Service (NWS) Office since 2003 and has since included several other offices to better implement LMA observations into real-time applications. Using Total Lightning Observations to Enhance Lightning Safety Preliminary work here investigates circulation from Weather Suveilance Radar- 1988 Doppler (WSR-88D) coupled with total lightning data from Lightning Mapping Arrays. Goal of fusion of total lightning with proven tools (i.e., radar lightning algorithms. Schultz, Christopher J.Īpparent relationship between total lightning (in-cloud and cloud to ground) and severe weather suggests its operational utility.
