武陵山区两种不同下垫面温度观测及对比分析

文章通过对铜仁国家基本气象站2007-2008年探测获得的水泥地面温度资料与日常地温场观测资料进行统计分析和对比研究,发现模拟高速公路和城市的水泥地表面与自然状态下的裸土地表面两者之间,在相同太阳辐射条件下不同的季节存在着不同的温度变化和散热差异,并分析了产生温度和热力差异的原因,对比分析发现,水泥地面在夏、春季节增温效果最明显,对城市"热岛效应"的贡献较大,同时找出了水泥地面和裸土地面两者的地表平均温度、最高、最低温度在高温、降水和凝冻天气条件下的温度变化规律,掌握不同下垫面温度变化规律,有助于台站开展交通路面温度预报、道路结冰预警信息发布以及城市气象服务。

Wuling Mountain Two Kind of Different Underlying Surface Temperature Observation and Comparative Analysis

This article through to the Tongren national basic meteorological station from 2007 to 2008,the cement surface temperature detection data and daily temperature field observation data for statistical analysis and comparative study,found the simulated highway and city cement surface and the natural state of the bare soil surface between the two,in the same solar radiation under the conditions of different seasons have different temperature change and heat difference,and makes an analysis of the temperature and the thermal difference,comparison analysis,the cement ground in summer,spring warming effect is the most apparent,the city "heat island effect" significant contribution,and find the cement floor and bare soil surface of both the average temperature of the earth’s surface,the maximum,minimum temperature in high temperature,precipitation and freezing weather conditions of temperature change rule,grasps the different underlying surface temperature change law,contribute to carry out traffic pavement temperature prediction,road icing warning information release and the city meteorological service.
