Climatology of Snow in Shikoku District

Abstract

The date of the first snowfall, the date of the last snowfall, the number of days of snowfall and the maximum depth of snow cover are the most popular climatological data. But it is questionable that these data are usefull to lay plans in various industries as well as in agriculture.
Therefore, the seasons and the geographical distribution of heavy snowfall in Shikoku District are investigated. In Shikoku District, the snow cover generally soon melts away, but by districts or years, it covers the ground for a period of time, and the same phenomena as are called NEYUKI (continuos snowcover) can be recognized, The statistics of the probable maximum snow depth are better fit for climatology in the District.
