SOME APPLICATIONS OF THE CAPPI TECHNIQUE OF RADAR PRESENTATION IN SYNOPTIC DIAGNOSIS AND RESEARCH

摘要

CAPPI records of the McGill CPS-9 radar comprising four cyclonic, cold-seas on precipitation periods are analyzed. The CAPPI technique is found to have valuable applications as an additional tool in the synoptic diagnosis of precipitating systems and for research purposes but as a sup-plement rather than a replacement for the conventional PPI and RHI tech-niques. For operational use outside of the "umbrella" area the practical advantages of CAPPI over those of other presentations in this type of situa¬tion are not self-evident from this limited analysis. The use of CAPPI in summer convective situations is not considered.
