摘要
Abstract
By using snow depth, snow-layers density, water content and snow-layer temperature data of northern Xinjiang in mid-February of 2009 and 2010,this study analyzed the property features of snow parameters and their relationships. The results showed that, ①The temperature of snow-soil interface was about 3 ℃ higher than the snow surface when snow depth was 10 cm,so did 6-10 ℃ with snow depth more than 10 cm. There was a linear correlation between snow-soil interface temperature and snow depth; the deeper the snow cover,the more significant the holding thermal effect. ②With more snow weather in northern Xinjiang since January 2010,snow depth in February 2010 was significantly higher than that in 2009 over the same period. ③Mean snow density range of 0.15-0.272 g/cm^3 in February 2010 was higher than that in 2009 with snow density range of 0.087-0.225 g/cm^3 through Northern Xinjiang. ④In certain interval range of volumetric water content, the snow density linearly correlated with the volume water content.关键词
