摘要
根据湖北省76个国家地面气象观测站1960-2023年逐日平均气温数据,按照气象行业标准《气候季节划分》,统计了逐年四季开始时间、结束时间及季节长度,并分别对20世纪60年代、70年代、80年代、90年代和21世纪统计了各年代年平均季节长度及平均气温。对以上统计分别进行了对比与分析,结果表明:湖北省大部时间在3月份入春,5月份入夏,9月份入秋,11月份入冬,春、秋季较短,夏、冬季较长。自20世纪60年代至今,平均气温总体呈上升趋势,春、夏季有提前到来的趋势,秋、冬季有推迟的趋势,季节时长也在逐渐变化,春季变化不大,夏季明显变长,秋、冬季变短,尤其是冬季缩短明显。
Based on the daily average temperature data from 76 national surface meteorological observation stations in Hubei Province,spanning from 1960 to 2023,and in accordance with the meteorological industry standard Division of Climate Seasons,the start and end times of the four seasons were determined each year,along with their respective lengths.The average annual season lengths and average temperature for the 1960s,1970s,1980s,1990s,and the 21st century were calculated.This paper compares and analyzes the aforementioned statistics.The results indicate that spring typically begins in March,summer in May,autumn in September,and winter in November.Spring and autumn in Hubei Province are shorter,while summer and winter are longer.Since the 1960s,the average temperature in Hubei Province has exhibited an overall upward trend.There is a tendency for spring and summer to arrive earlier,and for autumn and winter to be delayed in their onset.Notably,the winter season has experienced a significant reduction in length.
