説明
We found a good correlation (R2=0.79) between the BTS (Basal Temperature of Snow) value and thickness of the depth hoar layer in a block slope at Mt. Higashi-nupukaushinupuri (1251 m a.s.l.), central Hokkaido. Temperature gradients of snow were estimated from air temperature and snow depth data in the nearest meteorological station. Maximum temperature gradients appeared in December, when snow cover was thin. This fact suggests that the temperature gradients in December can promote growing of depth hoar layers not only in the high BTS condition, but also where BTS is low. Therefore, depth hoar layer thickness may vay between high and low BTS conditions in January and February, when snow cover reaches a maximum. We conclude that the thickness of the depth hoar layer reflects the difference of the BTS value in winter.
