西北典型城市供暖季气象参数规律研究
Meteorological parameters in heating season of typical cities in northwest China
摘要：
采用中国气象台典型气象年数据，分别拟合出了西北3个典型城市——西安、西宁、银川供暖季阴天、多云、少云和晴天4种天气状况下室外温度和太阳辐射照度的函数表达式，拟合曲线与实测曲线相关性很好。以西安供暖季为例，用拟合温度函数计算得到的基本耗热量与根据现行规范用稳态方法计算得到的基本耗热量相比较发现，前者为后者的60%左右。

Abstract：
Based on the typical year data provided by the national meteorological observatory, fits the function expressions of outdoor temperature and total solar radiation quantity in overcast, cloudy, partly cloudy and clear days in Xi’an, Xining and Yinchuan. The functions and observed data are well matched. Taking Xi’an as an example，compares the basic heat load, which is obtained with the fitted temperature function, with that worked out using the steady-state method from the current regulation, showing that the former is about 60% of the latter.
