Abstract:Based on snow/ice surface thermal balance equation , the main factors influence the snow/ice sur-face temperature with ice temperature , net radiation , wind speed , ice thickness , humidity , cloudiness and air pressure .Considering certain factors on snow/ice surface temperature , changing this factor , other factors kept a relatively fixed , so as to analyze the sensitivity of the factors on the surface temperature influence .According to the statistical analysis of the in -situ observation dates in different time , which are the ice temperature , wind speed , solar radiation and ice thickness , measured in Hongqipao Reservoir Hei Longjiang Province and the data , which are cloud cover , humidity and sea level pressure in 2009 -2010 winter downloaded from Anda Weather Station in China Meteorological Data Sharing Service System , the main factors influencing the characteristic value are determined .On the basis of a range of factors in the actual value , the use of snow/ice surface heat balance equation , the corresponding reservoir simulation snow/ice surface temperature Nas Calculated was obtained through the sensitirity analysis .The formula between Hongqipao Reservoir of the above seven factors and the snow/ice surface temperature .The results can provide reference for the study of the formation and numerical sim-ulation of fresh water ice in reservoir .
