用三种方法划分潜江四季

Based on three Methods of Seasons Division

选用湖北潜江气象站1961—2010年逐月气温观测资料,对气温资料做了均一性检验及订正,用一元回归法分析了潜江地区近50年四季长度变化规律。分别以公历、侯平均气温、农历节气三种方法划分潜江四季,并比较各划分方法得出的结论差别。结果表明:对于潜江地区这三种划分季节方法中以侯平均气温划分法最为适用,潜江地区四季季节持续时间有明显差异,四季中以夏季最长,约4个多月;冬季次之,接近4个月;春季、秋季最短,各约两个月。

Based on temperature observation data of qianjiang station from 1961 - 2010, homogeneity test and reduction are made concerning daily average temperature in the last 50 years,a analysis is made by regression method on the four seasons length variation of Qianjiang area. Four seasons are divided by three methods about the Gregorian calendar, and Pentad average temperature,and lunar solar term. The results show that： Pentad aver- age temperature method is most suitable for Qianjiang, Qianjiang four seasons season duration are significantly different, summer season is approximately more than 4 months, winter is close to 4 months; spring, autumn are about each two month.
