摘要
利用武汉市黄陂区气象站1959年7月至2012年12月逐日平均气温,采用气象行业标准和自定法1-3划分气候季节,比较不同方法的异同点.结果表明,多年平均四季起始时间分别为3月16-20日、5月17-21日、9月24-27日、11月23-25日,年际差异达38~47 d;入春、入夏提前,入秋、入冬推后,但变化不显著;多年平均四季长度夏季130~131 d,冬季114~115 d,春、秋季各60d左右;夏季显著延长,其余季节缩短但不显著;对所有季节指标,行标法和自定法3结果几乎相同;自定法1、3起始时间分别为最晚和最早,说明自定法1最严格,行标法或自定法3最宽松;自定法2判断的季节不至于过早或过晚,适合在武汉市黄陂区使用.
The data of daily average temperature from July,1959 to December,2012 in Huangpi national meteorological observatory of Wuhan,one standard method according to 《Division of climatic season (QX/T 152-2012)》(short for S1) and three defined methods(short for D1 、D2、D3) were used to divide the local climatic seasons and compare the differences of all methods.Results showed that the average of beginning dates was 16-20/3,17-21/5,24-27/9 and 23-25/11.The yearly difference was 38~47 d.The spring and summer came early while the autumn and the winter came later.The average length of the summer and winter was 130~131 d and 114~115 d.The spring and the autumn lasted only 60 d or so.The summer extended significantly and the other seasons were shortened with no significance.The results of S1 and the D1 were same.The beginning dates of four seasons were earliest with D3 and latest with D1,indicating that D1 was most strict and S1 or D3 least strict.There was no obvious deviation by using D2,which was more suitable as the dividing standard of climatic season in Huangpi district of Wuhan city.
