自20世纪70年代末开始发展以来，计算机模拟已被公认为计算建筑物全年动态行为和能耗的最详细方法。然而，由于缺乏详细的每小时天气数据，它们在中国这样的大型发展中国家的使用受到了阻碍。对于计算机模拟，天气数据必须每小时至少记录温度、湿度、风速以及太阳直接辐射和总辐射。此外，为了避免天气年复一年的随机变化，天气数据应该是假设的典型年份，而不是实际的记录年份。 为了支持中国中部夏热冬冷地区住宅建筑能源标准的制定，作者最近开发了28个中国地区的典型气象年（TMY）天气数据，最终将扩展到69个。这些TMY天气数据来自中国机场报告的16年历史天气（1982-1997），并从美国气候数据中心（NCDC）获得。由于天气数据只记录不同高度的云层状况，因此，人们在根据云层信息以及温度、湿度和风速信息估算太阳总辐射和直接辐射方面做出了大量努力。 将两个地点的估计太阳辐射与实测每小时太阳辐射进行比较，得出的R20.87，而将九个地点的年总太阳辐射和漫射太阳辐射进行比较，则分别显示出5%和12%的标准偏差。人工TMY的创建使用了与美国TMY数据类似的方法，通过四个步骤从16个可用历史月份中选择最具代表性的月份。然后将12个代表月合并，形成每个城市的典型气象年。这些中国TMY天气文件将在CD上公开，作为2002年在日本出版的技术文件的一部分。 单位:SICitation:研讨会，ASHRAE交易，第108卷，第页。2.

Since their development starting in the late 1970s, computer simulations have become accepted as the most detailed way to calculate the dynamic behavior and energy use of a building over an entire year. Their use in a large developing country such as China, however, has been hampered by the absence of detailed hourly weather data. For computer simulations, the weather data must have hourly records of at least temperature, humidity, wind speed, and both direct and total solar radiation. Furthermore, to avoid the random variations in weather from year to year, the weather data should be for a hypothetical typical year, rather than an actual year of record.In support of the development of residential building energy standards for the Hot Summer/Cold Winter region in central China,the authors have recently developed typical meteorological year (TMY) weather data for 28 Chinese locations that will eventually be expanded to 69. These TMY weather data have been produced from 16 years of historical weather (1982-1997) reported by Chinese airports and obtained from the U.S. Climatic Data Center (NCDC). Since the weather data record only cloud conditions at various heights, a substantial effort was made toward estimating the total and direct solar radiation from the cloud information, combined with information on temperature, humidity, and wind speed. Comparisons of the estimated solar to measured hourly solar radiation for two locations resulted in an R2of 0.87, while comparisons of annual global and diffuse solar radiation for nine locations showed standard deviationsf5% and 12%, respectively.The creation of the artificial TMY uses a similar methodology to that used for the United States TMY data, with a four-step process to select the most representative month from the 16 available historical months. The 12 representative months were then combined to form the Typical Meteorological Year for each city. These Chinese TMY weather files will be made public on a CD as part of a technical document to be published in Japan in 2002.Units: SI
