地面温度与雪面温度对比

Comparison of Ground Surface Temperature to Snow Surface Temperature

通过平行观测,对德州市气象局所辖的陵县(2003～2004年)、武城(2004～2005年)、德州(2006～2007年)3站冬季有积雪时,人工站与自动站的地面温度观测资料进行统计分析,得出有积雪状况下的β值(β=自动观测地面温度/人工观测雪面温度)。自动观测的地面温度更能代表实际地面状况,这种对比关系可为使用地表温度的水文及农业部门提供一个更加准确的地面温度使用参数β,以掌握地面温度的变化规律,为地能、地热、地水的预测与判断提供准确数据。

Through parallel observation,the temperature data from both conventional stations and automatic weather stations （AWS） in winter with snow cover at three stations of Dezhou Meteorological Bureau （Lingxian,2003 to 2004; Wu Yi,2004 to 2005; Dezhou,2006 to 2007） are analyzed statistically. The ratio of conventionally measured snow surface temperature to the AWS measured under the condition of snow cover is gained. Since ground temperature can be better representative of the actual situation on the ground,the ratio can be used as a useful and better parameter in surface temperature measurement for scientists in the related fields such as hydrological and agricultural departments.
