NSSL scientists are also researching what the altitudes of these flashes might tell us about how ice and hail particles are changing within the storm. Some storms also produce additional VHF at the top of their updrafts, which might be used to monitor rapid changes in the updraft due to the continuous, three-dimensional nature of the OKLMA measurements. If these holes form, as suspected, just before a storm becomes severe, this information could alert forecasters to developing severe conditions. Better lightning mapping techniques show that some supercell thunderstorms have “lightning holes” where updrafts are located and precipitation is scarce. NSSL scientists hope to use the data from OKLMA to learn more about how storms produce intra-cloud and cloud-to-ground flashes and changes in lightning flashes are related to tornadoes and other severe weather. These high-resolution datasets are used to evaluate operational lightning observations which cover a larger area but which may have lower resolution or observe different physical processes that occur during a lightning flash. ![]() NSSL is also building a purely mobile set of stations to acquire lightning observations in field campaigns outside of Oklahoma. Thousands of VHF points can be mapped for an individual lightning flash within 200 km of the stations, to reveal its location and the development of the lightning structure. In April 2012, seven additional stations were added in southwest Oklahoma. Since 2003, there have been 10-11 stations in central Oklahoma. ![]() The times are transmitted to a central station, which computes the time, latitude, longitude, and height of the segment that radiated the signal. ![]() To do this, the system measures the time at which a signal radiated by a lightning channel in a VHF band (the former television channel 3 band) arrives at each station in the OKLMA network. The National Severe Storms Laboratory and the University of Oklahoma jointly operate the Oklahoma Lightning Mapping Array (OKLMA) to map the time and location of lightning channel segments within clouds in three dimensions with high resolution. ![]() Research Tools: Oklahoma Lightning Mapping Array ![]()
