The date of the first and the last snowfalls, the number of days of snowfall and the maximum depth of snow cover are widely used climatological data, but are not sufficient for a plan of various industries as well as agriculture. To improve the situation, the period and area of heavy snow fall in Shikoku Island are studied.
Generally the snow cover quickly melts away in this district, however, in some area or in some years it covers the ground for a long period of time, i. e, the phenomena called NEYUKI (continuos snow cover) in the snowy district are recognised. The necessity of estimation of probable maximum snow depth is discussed. Snow damage on the agriculture, traffics and electric powers, and a note on the histrical aspects of snow in this district are briefly described.
