摘要
根据齐河县2006—2016年逐小时气温资料,利用数理统计、度时法等对该县冬季集中供暖期内气温和采暖强度时间分布和变化特征进行分析。结果表明:(1)齐河县每年固定采暖时间为121 d,供暖期小时平均气温一日内最低值出现在07时,为-1.0℃,最高值出现在15时,为7.4℃;日平均气温最低值出现在1月23日,为-3.1℃,最高值出现在3月11日,为9.6℃;逐月平均气温1月最低,为-1.4℃,3月最高,为6.3℃,供暖期年平均气温平均值为2.6℃,2012年最低,2014年最高。(2)多年小时平均采暖强度平均值为15.4℃·h,一日内呈现单峰型分布,最高值出现在07时,为19.0℃,最低值出现在15时,为10.7℃。逐月小时采暖强度平均值3月最小,为11.8℃·h,1月最大,为19.4℃·h。一日内各小时平均采暖强度最小值,11月和12月出现在14时和15时,其余月份均只出现在15时;一日内各小时平均采暖强度最大值,3月出现在06时和07时,其余月份均只出现在07时。(3)供暖期各月累积采暖强度3月最低,1月最高。年累积平均采暖强度平均值为4.7×10^(4)℃·h,2014年最低,2012年最高。
Based on hourly temperature data in Qihe from 2006 to 2016,the characteristics of temperature and heating intensity of the heating period in Qihe was analysis,using climate statistics methods and degree-hours method.The results indicated that:(1)During the 121 days of Qihe heating period,the lowest hourly average temperature in the day occurred at 7:00,which was-1.0℃;the highest hourly average temperature in the day occurred at 15:00,which was 7.4℃.The lowest daily average temperature occurred on January 23,which was-3.1℃;the highest daily average temperature occurred on March 11,which was 9.6℃.The monthly average temperature was the lowest in January,which was-1.4℃,and the highest in March,which was 6.3℃.The annual average temperature was 2.6℃,The lowest value in 2012 and the highest value in 2014.(2)The hourly mean heating intensity was 15.4℃·h,and the distribution of hourly mean heating intensity was opposite to the temperature.The highest hourly mean heating intensity,19.0℃·h,was at 7:00 am,while the lowest value,10.7℃·h,was at 15:00.The average hourly heating intensity reached the minimum value of 11.8℃·h in March and the maximum value of 19.4℃·h in January.The minimum hourly mean heating intensity was at 14:00 pm and 15:00 pm in November and December,and was at 15:00 in other months of the heating period;the maximum hourly mean heating intensity was at 6:00 and 7:00 in March,and was at 7:00 in other months of the heating period.(3)During the period of 2006—2016,The cumulative heating intensity of each month reached the minimum value in March and the maximum value in January in heating period.The average annual heating intensity was 47173.1℃·h,the minimum value in 2014,and the maximum value in 2012.
