• Simultaneous work of the raindrop sampling and the radar observation was made in heavy rainfalls during the last stages of Baiu at Histoyoshi in southern Kyushu. The equation for the drop-size distribution was obtained in such well developed convective rainfalls in the form of N_D=N_0e^<-AD^2> (N_0=200, ⩘=1.2 R^<-0.5>, R: mm/hr, D: mm) at the drop size range larger than 1mm diameter. And it is quite similar to the stationary distribution computed by Srivastava^<19)>. This paper involves some considerations on the new obtained size spectra and rain parameters derived from it, and suggests that a combination effect of several different raincells may also be responsible for the new type distribution, in addition to the various kinds of cloud physical effects. The results of numerical experiments in relation to the observed characteristic distribution will be described in Part 2 of this paper.
