Abstract
Results from the PECAN (Plains Elevated Convection at Night) campaign are discussed. In particular, the utility of simple backscatter lidars/ceilometers in quantifying atmospheric dynamics parameters and variables as well as evolution of the lower tropospheric dynamics are made. Cases of bore wave dynamics and the potential of these events in lofting of low level, moist, airmass and its consequence in thunderstorm initiation are made. A suite of thermodynamic profiling instruments are combined and compared to describe and visualize lower tropospheric dynamic evolution.
Highlights
Figure-3: Profiles of (A) water vapor mixing ratio measured by the NASA/GSFC ALVICE Raman lidar (B) Vaisala CL31ceilometer measured backscatter (C) Temperature profile measured by the MTP and (D) Surface temperature and Pressure made at FP2 on 14 July 2015
Preliminary findings indicate that the ceilometer profile data is an excellent indicator of the tropospheric dynamics
When combined with surface meteorology data, these ceilometers could lead to a useful documentation and statistics of the occurrence of bore events
Summary
FP2 during stable boundary layer (SBL) conditions served as a hub for Profiling Microwave with large CAPE Comparison of lidar-radar-microwave and other The instrumentation was organized by teams profilers and assessment of their utility in from Howard University, NASA/GSFC and atmospheric dynamics studies.
