【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60 d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。
[Abstract]:Using the daily mean temperature of Huangpi District Meteorological Station from July 1959 to December 2012, the weather season is divided by using meteorological industry standard and self-determination method 1-3, and the similarities and differences of different methods are compared. The results show that the average starting time of the four seasons is March 16-20, May 17-21, September 24-27, November 23-25, the annual difference is 3847 days, spring, summer, autumn, winter, but the change is not significant. The average length of four seasons is 130 ~ 131 days in summer, 114 ~ 115 days in winter, 60 days in spring and autumn respectively, the summer is prolonged significantly, the other seasons are shortened but not significant, and the results of row standard method and self-calibration method are almost the same for all seasonal indexes. The starting time of the self-determination method 1 ~ (3) is the latest and the earliest, respectively, indicating that the method 1 is the strictest, the line standard method or the self determination method 3 is the loosest, and the season of self determination method 2 is not too early or too late, so it is suitable for use in Huangpi District of Wuhan City.
