SPATIAL VARIABILITY OF THE ASPECT SENSITIVITY OF VHF RADAR ECHOES IN THE TROPOSPHERE AND LOWER STRATOSPHERE DURING JET STREAM PASSAGES

Spatial variability of the aspect sensitivity of VHF radar echoes in the troposphere and lower stratosphere during jet stream passages

The aspect sensitivity of SOUSY-VHF-radar oblique-beam echoes from the troposphere and lower stratosphere has been examined for a number of jet stream passages during the years 1990 - 1992.When the core of the jet is overhead or nearly so, vertical profiles of the aspect sensitivity display two notable features.First, the distinction between mainly
