1961-2010年赤峰市采暖期气象条件分析

Analysis of Meteorological Condition of Heating Period in Chifeng During 1961-2010

利用赤峰市1961~2010年逐日气温,运用数理统计方法,对赤峰市采暖期气象条件进行分析,结果表明:(1)赤峰市实际采暖期平均气温为-3.5℃,呈波动上升趋势,气候倾向率为0.37℃/10a;(2)赤峰市理论平均采暖长度为153d,初日10月29日到次年终日3月31日,比实际采暖期少29d;(3)理论平均采暖长度呈逐年缩短趋势,气候倾向率为-3.3d/10a。(4)80%保证率下,赤峰市理论采暖长度为165d,采暖初日为10月24日,采暖终日为4月7日。

Based on the daily temperature from1961to2010in Chifeng,this article analyzed the meteorological condition of heating period in Chifeng with the method of Mathematical Statistics.The results were as follows:(1)The average temperature of actual heating period was-3.5℃which appeared rising trend and the climate tendency rate was0.37℃/10a.(2)The theoretical length of heating period was153days from29th October to31st March of next year.It was29days more than actual length.(3)There was a shortened trend of the theoretical length of heating period and the climate tendency rate was-3.3d/10a.(4)The theoretical length of heating period was165days,the first day was24th October and the last day was7th April with80%climate guarantee rate.
