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 lineartrend estimate， MannKendall 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.
