Internal Consistency of Meteorological Data Obtained with a Volume- Imaging, Multi-Receiver Radar Wind Profiler

摘要

The main goals of this project ('Internal consistency of meteorological data obtained with a volume-imaging, multi-receiver radar wind profiler) were (1) to identify as clearly as possible the mathematical relationships between radar wind profiler (RWP) signals and the turbulent atmospheric field in the radar resolution volume; and (2) to develop dynamical and other conservation equations for those properties of the turbulence field that we identify in Part (1). The mathematical relationships between the radar observables and the atmospheric fields have now been formulated in a very general manner. In contrast to all earlier RWP theories, the new theory allows not only the zeroth moment (backscattered power) but also all higher moments (Doppler shift, spectral width, etc.) of the Doppler spectrum to be rigorously expressed in terms of statistics of the velocity and refractive-index fields in the RWP's resolution volume. The theoretical results have been illustrated and enhanced by the analysis of RWP measurements and fine-wire, in-situ turbulence measurements.
