Precipitation Bands of Typhoon Vera in 1959 (Part I)

Abstract

A case study of the rainfall associated with Typhoon Vera (the Ise Bay Typhoon) in 1959 is made. From an inspection of hourly precipitation charts, one gets an imprestion that the rainfall amount with the typhoon is solely dependent upon the orographic elect. However, the analysis of time changes of rainfall intensity reveals the existence of well-organized zones of alternating heavy and weak rainfall intensity surrounding the storm center. The surface pressure field also contains similar banded structure. A comparison with the radar pictures shows the correspondence of these zones to groups of radar rain bands.
