From rainguage records, showery rainfalls from convective clouds were picked out, and the from of the time-section pattern of the rain intensity was investigated. It was found by means of some normalization that the form is expressed by the formula,
I=Aτmexp(-nτ), I=A
where I denotes intensity of rain,τ, time and m and n are constants. This typical form maintains in the developing stage of the convection cells up to moderate. The elementary cells as shown by the formula. are usually supposed to be amalgamated into one cell when the convection has grown up so as to bring an extremely intense rain such as more than 10 mm per ten minutes.
