摘要
利用1951~1990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,分析了梅州市气温、降水等气候指标的特征与变化。分析表明:上世纪50~80年代梅州市年均气温呈上升趋势,增长率为0.031℃/10e。不同季节气温的变化趋势不同,夏季变暖趋势最明显。根据这40年砖暖波动情况,可将梅州市气候划分成蕊个冷期两个暖期;历年降水量则呈上升趋势,多年降水倾向率为14.635mm/10a。春、夏、秋、冬各季节降水变化亦呈上升趋势。按照年降水波动变化,可将梅州降水分为两个多雨期与两个少雨期。
In accordance with the materials such as the temperature, the precipitation, the highest temperature, and the minimum temperature from 1951 to 1990 in Meizhou, and with the method of mathematical statistics, we analyze the key meteorological elements and the characteristics of climatic change nearly 40 years in Meizhou. The results show that the average annual temperature of Meizhou city from 1951 to 1990 rises obviously. The annual average temperature increases 0.031℃ every 10 years o But number of different seasons are different, The most obviously increased temperature appear in summer. According to the changes in temperature, the climate in Meizhou city can be divided as two cold periods and two warm ones. Furthermore, the precipitation ap- pears to rise during those years too (14. 635mm/10a). According to the changes of annual precipitation in Meizhou city during those 40 years, climate can been divided into two rich precipitation periods and two less precipitation periods.
