摘要
以暖温带地区恒温层平均温度为研究对象,选取7个代表城市,根据地温监测数据和气象资料,采用分析计算的方法,推导了两个暖温带地区恒温层温度计算公式,其拟合度分别为0.98和0.96。研究结果表明,利用气温、天空温度、风速、水平面直接辐射强度等气象资料,可以对恒温层温度做出较准确的预测,其中气温对恒温层平均温度的影响作用大于76%。只须向推导出的简化公式输入气温数据,即可计算出恒温层温度。该公式具有一定的应用价值。
By using measured data obtained from long-term monitoring in seven cities with typical warm temperate climate, two different calculation methods for temperature in the constant temperature zone have been developed, each registering a Satisfactory degree of 0.98 and 0.96. Results show that temperature of constant temperature zone can be forecasted accurately with data on air ambient temperature, sky temperature, wind velocity and solar radiation density on a horizontal surface. What＇s more, air ambient temperature is the dominant parameter weighing more than 76%. The simplified correlation which is only a function of the air ambient temperature has a broader application.
