Distributions of amount of rain with rainfall rate and of duration with rate are determined for all rain of 1963 and for the heavy rain of 1958 to 1962. The rainfall rates are obtained from the rain chart records of the McGill Cbservatory tipping-bucket recording rain gauge. Separate distributions for winter and summer rain are evaluated. The distributions of amount with rate for both winter and summer rain are log-normal; they have logarithmic means of 2.5 mm hr⁻¹ and 12.6 mm hr⁻¹ respectively and logarithmic standard deviations of 0.4 and 0.7 respectively. A comparison of the distributions of amount with rate for winter rain and for snow shows that the two distributions are similar in form. [...]
