Abstract
From a statistical investigation the authors have found a clue to the seasonal forecast for the probable deepest snow in the comming winter in Etigo province. They found a high correlation as 0.86±0.04 between the deepest snow in Etigo and the difference of the monthly average of the atmospheric pressure for the preceding November at Hankow in China and at Niigata. They add remarks that if a certain allowance is made for the influence of solar activity the correlation may be raised so high that it seems to be practicable.
