| 摘 要： | 利用1953年～2006年梅州市气候资料。运用线性回归方程、相关分析等数理统计方法,分析了梅州市近50年来气温、降水和风等气候指标的特征与变化。分析表明:梅州市多年平均气温为21.3℃;冬季气温变异系数大,温度变化幅度大,稳定性差;全年温差小,最热月与最冷月平均温差小于加℃,热量资源丰富,全年积温>7600℃。多年平均降雨量为1526.2 mm.,年降水变差系数较小,尤其春夏季降水相对集中而稳定;梅州降水以中雨和大雨为主。暴雨和特大暴雨比例不多。仅占4.82%。季风特征明显,风速小,多年平均风速为0.96m/s,大风天气少。

| Abstract: | According to the climatic data of The West of Meizhou city from 1953 to 2006,the climatic in- dexes,for example,temperature,precipitation and wind was analysed.The results show that the annual aver- age temperature is 21.3℃and the comparative difference of annual average temperature is 15.1℃.The temperature variance modulus is large and unstable in the winter.The precipitation is centralized and dis- tributed unevenly in a year.The annual average precipitation is 1526.2 mm and the annual average precipi- tation in the winter half-year is 306.2mm.In addition,the comparative difference of the annual average precipitation is comparatively large and unstable in the autumn or winter.The days of precipitation are few and distributed unevenly in a year.At last,the annual average wind speed is 0.96 m/s.The annual gale- times are less than other areas in Guangdong. |
