建筑热环境分析干球温度逐时计算方法比较：以上海地区为例
Comparison of hourly dry-bulb temperature calculation methods for analysis of building thermal environment:Taking Shanghai area as an example
摘要：
选择上海某台站2012年每日4次定时干球温度，分别采用调和分析和三次样条方法计算其全年逐时温度，比较了2种方法的计算结果与实测值之间的均方根误差与绝对误差，讨论了这2种方法的计算精度与适用性。结果表明：调和分析与三次样条方法均能满足典型气象年生成与室外计算参数统计的要求；三次样条方法的计算精度略高于调和分析。
Abstract：
Selects the values of 6h interval dry-bulb temperature of a station in Shanghai in 2012, and calculates the hourly dry-bulb temperature with Fourier series and cubic spline function method, respectively. Compares their calculation results and hourly observational temperature values using root-mean-square errors and absolute errors, and discusses the accuracy and applicability of the two methods. The results indicate that the two methods can meet the requirements of generation of typical meteorological year and the statistics of outdoor calculation parameters. The accuracy of cubic spline function is slightly higher than that of Fourier series.
