Coordinated Radar and Aircraft Observations of Turbulence.

Abstract

Interim results of a program to measure and correlate radar-and aircraft-sensed turbulence in rainstorms are presented. The dissipation factor of a turbulent air mass can be measured by an aircraft and a weather radar. Comparisons are made between precipitation reflectivity and spectral width measurements as indicators of turbulence. The instrumentation and data processing procedures are described. Examples of turbulence observations made with a storm-penetrating aircraft and the weather radar are given. The relationship between the radar observations and the physical properties of the turbulent atmosphere are derived. The relationship of radar spectral width (variance) to turbulence intensity is discussed. (Author)
