Abstract: In this study, snowfall frequency analysis was performed to determine the best fit distribution applicable for Korean in order to make asnowfall frequency map. The available 66 stations having a snowfall over 20 years were selected and the annual maximum snowfallwere collected. Generalized Extreme Value, Gumbel, Weibull, 2-Parameter Gamma, 3-Parameter Gamma and Log-Pearson Type IIIdistribution which are useful to extreme value frequency analysis were applied to determine appropriate distribution for Korea. TheMethod of Moment and the Probability Weighted Moment Method were applied as parameters of the distributions. The results showthat Weibull distribution by Probability Weighted Moment Method is the best fit for snowfall frequency analysis. Mapping snowfallfrequency were accomplished using snowfall frequency according to the available 66 stations through Kriging method by ArcGIS.Snowfall frequency map is expected to be useful in the design of building structures against heavy snow loading throughout Koreamost especially in ungauged areas.
