Simulation of attenuation by rainfall at a wavelength of 5 cm
Abstract
Simulated rainfall rate attenuation at a radar wavelength of 5 cm has been obtained in order to quantitatively determine effects of attenuation due to rainfall. Digital data collected with the 10 cm NSSL WSR-57 radar is used to compute the attenuation estimate expected with a 5 cm radar. Two cases involving heavy rainfall from Oklahoma thunderstorms are examined: an organized squall line which occurred on June 6, 1975 and produced radar-measured rainfall amounts in excess of 80 mm with rates exceeding 100 mm/hr; a succession of convective rainshowers which repeatedly formed and matured in the vicinity of Enid, Oklahoma on October 10, 1973.
