Changes of Snow Characteristics During Snowmelt Period and Analysis of Influential Factors - Taking the Juntanghu Watershed in XinJiang as an Example

Abstract:

Take observational data of March 2011 of study area to analyze changes of snow characteristics during snowmelt period (SP), such as snow grain size (SGS), snow water content (SWC) and snow density (SDS), and to analyze the influential factors. The results show that: SGS decreased during SP, and increased from snow surface layer (SL) to snow bottom layer (BL). That related to the snow depth (SD) and snow temperature (ST). SWC has a sudden increase in late SP. It decreased from snow BL to SL during early and late SP. It has a big daily variation in SL and snow middle layer (ML). It changes hours later than the atmospheric temperature (AT). That related to SD, ST and daily AT. SDS value in SL is the biggest during early SP. It has acute change in SL and a big daily variation in BL .That related to snow age (SA).
