Finescale Vertical Structure of a Cold Front as Revealed by an Airborne Doppler Radar

摘要: Abstract In the afternoon of 24 May 2002, a well-defined and frontogenetic cold front moved through Texas panhandle. Detailed observations from series platforms were collected near triple point between this dryline boundary. This paper primarily uses reflectivity Doppler velocity data an airborne 95-GHz radar, as well flight-level thermodynamic data, to describe vertical structure it intersected with dryline. The prefrontal convective boundary layer was weakly capped, sheared, about 2.5 times deeper than cold-frontal density current. radar depict fine example atmospheric current at unprecedented detail (∼40 m). echo dual-Doppler-inferred airflow in plane reveal typical features such nose, head, rear-inflow current, broad rising air that feeds accelerating front-to-rear over head. 2D cross-fro...
