Radio acoustic sounding system (RASS) and wind profiler observations of lower- and midtropospheric weather systems

Abstract

The wind and temperature remote-sensing systems observed wind-velocity and virtual-temperature structures associated with a synoptic-scale trough and embedded fronts, and a propagating short-wave trough and trailing midtropospheric jet-stream-frontal-zone (jet-front) system. Single-station hourly diagnostic calculations of geopotential heights, horizontal virtual potential temperature gradients, thermal advections, vertical velocities, gradient Richardson numbers, and cross-frontal isentropic potential vorticity demonstrate that dynamically consistent synoptic-scale and mesoscale signals can be obtained by combining wind profiler and RASS observations. -from Authors
