Abstract
From the standpoint of applied meteorology, it is a very important problem to decide the area to which the amount of a rainfall at a weather station is applicable.
In this paper the authors try to decide the area and shape of the regions where the amounts of a rainfall by a front or typhoon differ from those observed at several stations in the Kanto district by less than ±10, ±20 or ±30%.
And the following results are obtained.
1) Fig. 1 shows the variation of shape in the applied area.
2) Fig. 2 shows the relation of the applied to the rasio of permission.
