摘要
Abstract
Taking samples of 451 days when snow depth is greater than or equal to 0 cm from November 2006 to March 2010 at the automatic weather stations in Tacheng, ground temperature, snow or grass surface temperature, 0 cm surface temperature, cloudiness, sunshine time and snow depth were analyzed. The results show as follow: the snow or grass surface temperature was consistent with air temperature, and it was influenced obviously by cloudiness and sunshine time, and the average snow surface temperature was lower than the average air temperature in snow season; there are two distinctions when ground temperature varied with snow depth: 20 cm and 50 cm; when snow depth was less than or equal to 20 cm, the ground temperature was greatly influenced by snow depth and air temperature, and its change trend was mainly consistent with air temperature, and the ground temperature was higher than air temperature; when snow was thinner, the ground temperature was influenced obviously by cloudiness and sunshine; when snow depth was more than 20 cm but less than 50 cm, the ground temperature was only influenced by the long time air temperature change, therefore, the ground temperature varying ranges tended to a fixed value, and it was no less than -5 ℃; when the snow depth was more than 50 cm, the ground temperature tended to the fixed value (-1 ℃).关键词
