黑龙江地区水库雪/冰表面温度特征分析

Analysis on the features of snow/ice surface temperature in reservoirs in Heilongjiang

根据雪/冰表面热平衡方程以及黑龙江大庆红旗泡水库2009年冬季现场观测数据和在中国气象数据共享网上下载的安达气象站有关气象数据,模拟计算出红旗泡水库2009年冬季的雪/冰表面温度,发现雪/冰表面温度、气温和净辐射之间存在明显的周期性变化,分析研究了雪/冰表面温度的特征及规律,在此基础上得到雪/冰表面温度最低和最高设计值.统计现场观测气温得到谷值气温一般出现在凌晨,且大多集中在7：00~8：00之间,是以往选取凌晨6：00气温作为最低设计冰温的一个佐证.

Based on snow/ice surface thermal balance equation and data from observations at Daqing Hongqipao reservoir in the winter of 2009, and some meteorological data of Anda Weather Station downloaded from China Meteorological Data Sharing Service System , the snow/ice surface temperature on the reservoir was simulated. Clear periodical changes of the surface temperature, air temperature and net radiation were found. The characteristics and regular patterns were analyzed. Hence, the minimum and maximum design snow/ice sur- face temperatures are obtained. The measured cold temperature generally appears in the morning, and most are between 7：00-8：00. This supports the previous method that 6：00 air temperature is selected as the minimum design ice surface temperature.
