| 摘 要： | 利用潮州市饶平地面气象观测站1956—2008年气温观测资料,运用线性倾向估计、Mann-Kendal突变检验、小波分析和累积距平等分析方法对近53年来温度变化的主要特征进行分析。结果表明,近53年来平均气温呈增加趋势,线性增温速率0.17℃/10a,突变点在1994年,其主振荡周期的时间尺度为18年;季节温度变化最显著特点为冬季增温最明显,突变出现时间最早,在1987年,其次是秋季、夏季,最后是春季,突变点在1994、1995年附近;据季节温度振荡主周期判断,在大的时间尺度上各季节目前均处于偏暖期,但较小尺度上（2~4年）,夏、秋季目前处于偏暖期,冬、春季处于偏冷期;1990年至今,大于等于0℃、10℃的活动积温处于回升阶段。 |

| Abstract: | Based on the air temperature data of meteorological stations from 1956 to 2008,the characteristics of temperature change in Chaozhou for recent 53 years are studied,by using the linear-trend estimate,Mann-Kendall catastrophe test,wavelet analysis,and accumulative anomaly methods.The results indicate that annual average temperature had an obviously increasing tendency during the 53 years,and increased by 0.17 ℃ per 10 years;the mutation point was in 1994,and the main period of temperature oscillation was 18 years;the most notable feature of seasonal temperature change was warming in winter,with mutation occurred the earliest in 1987,followed by autumn,summer,and spring,with mutation point being in 1994 and 1995.According to the main periods of seasonal temperature change,at a large time scale,the present time is mainly in the warmer period,and at smaller time scales,summer and autumn in the warmer period,while winter and spring in the cooler period.The active accumulative temperature of greater than 0 ℃ and greater than 10 ℃ had significant upward trends since 1990. |
