An Analysis of Stationary Rainbands as Observed by Radar ( I )

Abstract

An analysis is made of the formation and the feature of stationary rainbands observed in western and eastern Kanto District. It is shown that the generation of a small elementary cell depends on the atmospheric condition and the topography of the peninsulas, and that the principal factors governing the formation of astationary rainband are the vertical wind profile and the depth of the moist layer. Furthermore, in order to examine the effect of trigger action due to topography, the distribution of updraft by topographies is calculated.
