The Plains Elevated Convection at Night (PECAN) field campaign is a multi-agency project (DOE, NSF, NASA, NOAA) in collaboration with national and international universities. The campaign is designed to understand the conditions that lead to convection initiation of thunderstorms and the evolution and lifecycle of large-scale systems at night. Understanding the initiation and evolution of convective systems will lead to an explanation of the observed night time maxima in summer precipitation over the central plains and help improve nation's forecasting and weather prediction capabilities. PECAN has four themes of research, which includes: documenting night time bore wave disturbances, Nocturnal mesoscale convective systems (MCSs), Nocturnal convective initiation (CI), and evolution and character of the low level Jet (LLJ). The University of Maryland Baltimore County deployed their research instrumentation at the FP2 site in Greensburg, KS. Data was collected from different instrumentation that consisted three types of lidars: Raman lidar, Doppler wind lidar, and the Elastic lidar. Other instruments operated at the site include the MicroWave Radiometer (MWR), Radiosondes, and an x-band radar (named X-BADGER) was also operated in order to document the variabilities in the nighttime atmosphere. This study will use data from PECAN (June 1 to July 15, 2015) and investigate the occurrences, evolution and structure of undulare Bore and build a statistics at FP2, in Greensburg, KS.
