| 摘 要： | 利用华南区域110个气象站1961-2008年逐日平均气温资料,计算华南区域各地年降温度日和采暖度日,分析降温度日和采暖度日的时空变化特征,探讨度日与年平均气温的关系.结果表明:华南区域年降温度日具有南部大、北部小,河谷平原大、山区小的地域分布特点;年采暖度日则是由南向北增大.1961-2008年华南区域年降温度日呈现...

| Abstract: | With the daily mean temperature data form 1961 to 2008 at 110 meteorological stations in South China, the annual cooling degree days and the annual heating degree days are calculated, their spatio-temporal variation characteristics are analyzed, and the relationship between degree days and annual mean temperature is investigated. The results show that the geographic distribution characteristics of annual cooling degree days in South China are that they are larger in southern part while smaller in northern p... |
