近畿地方南部の降雨について

Abstract

Relations of stability and horizontal water vapour flux to 24-hour precipitations inwarm season for two years are investigated. But we use here south-wind componentof mean wind in the lower atmospheric layer for the horizontal water vapoux flux. As24-hour precipitations we take (a) precipitation at Shionomisaki where upper airobservatinns are carried out, (b) maximiuu. Precipitation in the region which iswithin about a hund-red kilometers from Shionomisaki and ? mean precipitationin the same region. E~'en for the heavy rainfall, stability remains nearly neutral.And especially for the large sc~Ie heavy rainfall, it is considered that strong south-windcomponent of lower layer wind is necessary.
