Linear Precipitation Characteristics in the Atmosphere.
Abstract
This three year study was designed primarily to investigate variations in precipitation characteristics along lines. Instrumentation utilized included a dual wavelength (3 and 10 cm) radar, recording raingages, and raindrop spectrometers, all partially operated with support from other sources. Radar data recorded and analyzed were confined to azimuths in the immediate vicinity of the radial along which the raingages and spectrometers were located, and elevation angles from 0 deg -4.5 deg above ground. Radar reflectivity and attenuation were measured by the radar system, with liquid water content calculated from the attenuation information. The surface raingages were utilized to obtain rainfall rates and amounts while the raindrop spectrometers yielded dropsize spectra as well as rainfall rate data. The radar data indicated large, small-scale variations for the variables measured along the radar radials of interest for four rain periods examined. Both convective and stratiform precipitation were sampled, the convective rains having greater maxima of the variables as well as greater time and space variability for the measured parameters.
