We see this as an issue of fundamental importance to advancing our understanding of storms, especially given the recent interest in the lower boundary as a possible source of horizontal vorticity for the low-level mesocyclone and tornado. This topic might seem rather esoteric in terms of operational meteorology, but we see this as an issue of fundamental importance to advancing our understanding of storms. If we are ever to have Warn-on-Forecast capabilities at high resolution, we need to improve the representation of near-surface wind profiles in numerical simulations, which requires that we obtain fundamental new knowledge in what near-surface wind profiles look like in reality.
Vertical wind profile data obtained from Doppler lidars in VORTEX-Southeast in 2016 and 2017 [the Collaborative Lower Atmospheric Mobile Profiling System (CLAMPS) and NOAA/ARL lidar] allow us to assess the departures from M–O predictions in and near convective storms. Preliminary results will be presented at the conference.
