摘要
利用2012年1—3月玛曲站的观测资料和单点模式Noah_LSM,通过敏感性试验研究了3次积雪过程对近地层气象要素的影响。结果表明:(1)Noah_LSM模式能较好地模拟出近地层气象要素的变化特征;(2)敏感性试验1模拟的净辐射、感热通量、潜热通量、气温和30、60 cm土壤温度均大于控制试验的模拟结果;(3)敏感性试验2模拟结果表明较大的风速可能是造成2月18日出现大潜热通量和负感热通量的一个原因。
Based on the observation data at Maqu station from January to March 2012,and single point Noah_LSM model,the influence of three snow cover processes on the meteorological factors near surface was studied through sensitivity tests. The results are as follows：（ 1） The Noah_LSM model could better simulate the variation of meteorological factors in the surface layer;（ 2） The simulation value of the net radiation,sensible and latent heat fluxes,temperature,and soil temperature at 30 cm and 60 cm of the sensitivity test 1 were all greater than the results of the control experiment;（ 3） The sensitivity test 2 showed that the larger wind speed could be one of the reasons for the large latent heat flux and the negative heat flux on February 18 th.
