摘要:

利用1960—2009年武汉城区与郊区气象站逐日平均气温资料,采用相同气候季节划分方法,系统分析武汉城区与郊区气候季节起始时间、季节长度的变化趋势及其差异。结果表明:1980—2009年,武汉城区入春、入夏时间比郊区分别提前10 d和5 d,入秋、入冬时间城区比郊区推迟;武汉夏季长度城区比郊区长12 d,冬季、春季长度城区比郊区短6 d和5 d。1960—2009年武汉四季平均起始时间城区与郊区差别较小,但四季最早、最晚出现时间年际差别较大;武汉入春、入夏时间城区与郊区均提前,入秋、入冬时间均推后,但城区四季变化较显著,郊区仅入秋变化显著;武汉城区夏季长度呈极显著延长,冬季长度呈较显著缩短,城区春季、秋季及郊区四季长度变化均不显著。2000—2009年武汉城区与郊区季节起始时间和季节长度的变化较大,这是因为近10 a武汉作为中部地区崛起的支点,城区发展迅速。

Abstract:

Using daily average temperature data at two weather stations in urban area and suburb of Wuhan from 1960 to 2009, the beginning date and ending date of seasons, seasonal duration and their trends as well as differences were analyzed using a method of division of same climatic seasons. The results indicate that the beginning dates of spring and summer during 1980-2009 are in advance of 10 days and 5 days in urban area of Wuhan than in suburb, while those of autumn and winter is prolonged. Summer duration is 12 days longer in urban area than in suburb, while winter and spring duration is 6 days and 5 days shorter in urban area than in suburb. Mean beginning dates of four seasons have no significant difference between urban area and suburb during 1960-2009. However, the first and latest beginning dates differ significantly for annual variation of four seasons. The beginning dates of spring and summer both are in advance in urban area and suburb, while those of autumn and winter are prolonged. In general, seasonal variation is obvious in urban area, while only the beginning date of autumn changes significantly in suburb. Summer duration is prolonged significantly in urban area, while winter duration is shortened. Spring and autumn duration in urban area has no significant change, so is seasonal duration in suburb. Variation of the beginning date of seasons and seasonal duration during 2000-2009 in Wuhan is caused by rapidly urban development as an important city in the middle of China.
