COMPARISONS OF TIME INTEGRATED RADAR DETECTED PRECIPITATION WITH SATELLITE OBSERVED CLOUD PATTERNS
Abstract
Results of analyses of comparisons between synoptic scale radarscope data and TIROS I television cloud pictures are presented. The objective was to ascertain if precipitating clouds an be distinguished from non-precipitating clouds in the satellite pitures. Radar echo patterns integated over an extended period of time by a procedure that simulated moving the rdar station along with the precipitation system were compared with the satellite observed cloud patterns. Nine different cases are presented, showing precipitation-to-cloud relationships in varying synoptic situations and in different climatic regions of the world. The limitations of radar as an instrument for detecting precipitation are discssed as to their effects on the basic objectives of the study. The limitations of the satellite cloud photos and the ifficulties in working with these types of data are also discussed. Although some measure of success was achieved, the coarseness of the dta (both radar and satellite) precludes a conclusive determination of whether or not precipating clouds evidence unique characteristics that distinguish them from non-precipitating clouds.
