Reflectivity-rain rate relationships for convective rainshowers in Edmonton

A reflectivity-rainfall rate (Z-R) relationship is derived from Carvel radar and Edmonton rain gauge measurements. Our analysis indicates that the traditional point-by-point comparison method is not accurate for Alberta summertime precipitation due to timing errors in fast moving convective storms....

Zusammenfassung:A reflectivity-rainfall rate (Z-R) relationship is derived from Carvel radar and Edmonton rain gauge measurements. Our analysis indicates that the traditional point-by-point comparison method is not accurate for Alberta summertime precipitation due to timing errors in fast moving convective storms. The Window Probability Matching Method (WPMM) was superior and provided a robust Z-R relationship in the form of Z = 32.5 R super(1.65).
