Abstract
At the Simoda Marine Biological Station belonging to the University of Literature and Science, Tokyô, the daily amount-of rainfall was observed together with other meteorological elements under the, direction of the Geographical Laboratory since June 1934.
In order to study the minute distribution of rainfall around Simo da r daily observations were made at eight places (Fig.2) from June 1935. These results, together with the data for two other places are treated, and distribution maps drawn with respect to the individual rainfall caused by the twenty travelling cyclones that occurred up to the end of the year.
These twenty cases are classified into five major types according to the characteristics of their areal distribution, their relation to wind-direction being considered the most important. That is to say, in most cases, areal distribution is determined by adiabatic cooling caused by forced ascending currents along the mountain slopes, while the increase from the northern highland to the southern lowland is explained by up-lift of the rain-bearing stratum caused by the descending current from the north.
