摘要
本文采用典型气象年法对宿州地区1986-2015年气象参数进行计算分析,得出HDD、CDD值。采用平均年法对HDD、CDD值的逐年变化规律与变化趋势及年分布特征进行了分析研究。定义了基于HDD/CDD值的冷热强度与程度的概念。结论如下:典型气象年宿州地区HDD、CDD值为2009.4℃·d和155.8℃·d。1月采暖度日数占全年采暖度日数1/4。7月制冷度日数占全年制冷度日数近1/2。HDD值在30年中呈下降趋势,冷强度极值增加,相同冷强度下的冷程度减小。CDD值呈上升趋势,热强度极值增加,相同热强度下的热程度增加。过渡月份异常天气的频次增多,冷热强度增大,16℃冷强度值为5.9℃·d与26℃热强度值为1.0℃·d。
This paper uses the typical meteorological year method to calculate and analyze the meteorological parameters of 1986-2015 in Suzhou area,and obtains the HDD and CDD values.The average annual method is used to change analyze the HDD and CDD values year by year,the trend of change and the annual distribution characteristics.Innovatively defined the concept of thermal intensity and extent based on HDD/CDD values.Conclusions as bellows:in the typical meteorological year,the HDD and CDD values in Suzhou are 2009.4℃·d and 155.8℃·d;January heating degree days accounted for 1/4 of the annual heating degree days.The number of cooling degree days in July accounted for nearly 1/2 of the annual cooling degree days.The HDD value decreased in 30 years,the extreme value of cold intensity increased,and the coldness decreased under the same cold intensity;the CDD value showed an upward trend,and the thermal intensity extreme value increased.The heat level under heat intensity increases;the frequency of abnormal weather in the transition month increases,and the heat and cold strength increases.The 16℃cold intensity value is 5.9℃·d and the 26℃heat intensity value is 1.0℃·d.
