Study on Chaff Diffusion and Polarization Stratification

A new polarization property of chaff cloud is found, differential reflectivity varying with height during diffusion. The differential reflectivity (ZDR) of chaff fiber can be predicted as a function of time and initial orientation. The description of the chaff properties statistical changes from integrated to sectional, which Using this property, distribution curve of differential reflectivity will be plotted after the release of chaff fiber. The results of differential reflectivity stratification can be used as an explanation of the chaff event at the Key West, FL KBYX WSR-88D site on 17 June 2016.
