Comparative Snow Distribution Analysis of Japan Sea Side Basin in Tohoku District

Abstract

 The purpose of this study is to prepare basic snow distribution data to areas along the Sea of Japan. It is useful in estimation future snow distribution due to climate change. As study targets, we try to verify relationship between surface sea temperature (SST) and snow depth distribution. And, we obtained local snow condition to characterized ion composition change. These examination induced influence degree of Japanese seawater. These results are as follows; (1) Japan sea side area include basins effected by SST and cold air mass of continental origin, and the quantity of snow changes due to it. (2) As usual snow condition, the snow distribution of the seawater origin depends on the river topography condition base on CL^-/NA⁺ ratio analysis. (3) A local characteristic snow process exists in much snow areas distance left from the coast.
