Present paper aims to forecast the maximum snowcover depth H in every winter in Fukui city, in which H varies remarkablly 23-213cm during the period of 1898-1989. The writer reported previously some methods based upon (1) the daily variation of snowcover depth in early winter and (2) the daily variation of air temperature in Nov. and Dec., and (3) periodic behaviors of H. These methods have respectively characteristics but also faults.
In the present paper the writer discusses a forecast successively in three stages by combining of these three methods, and some technique in the calculation are described. The forecast of H is obtained with the fitness probability P=98% within the error +25--50cm.
