RAINFALL INTENSITY--FREQUENCY RELATIONSHIPS FROM MONTHLY EXTREMES

An approach is outlined for the development of rainfall extreme value distributions utilizing many extreme values per year. In particular, an extremal distribution is developed on the basis of monthly extremal distributions which are double exponential in form. The approach, applied to rainfall extremes of various durations at three stations in southern Ontario, offers an alternative to the estimation of distributions using only annual extremes. This alternative is shown to be less sensitive to the effects of outlier points and increases the utilization of rainfall information. It also reveals seasonal patterns of rainfall extremes which may be important for the consideration of rainfall--runoff determination. /Author/
