| 摘 要： | 采用气候倾向率、序列相关系数和累计距平等分析方法,对沈阳市1951～2008年温光水历史资料进行计算分析。结果表明：1951～2008年沈阳市气温呈明显增加趋势,光照呈明显减少趋势,降水量趋势变化不明显;气温趋势升高1.4℃,1980年是气温变化的跃变点,其前后气温平均升高0.8℃;冬半年是气温升高的主体;总热量趋势增加290℃;日照时数趋势减少320h,1982年是日照时数变化的跃变点,其前后日照时数平均减少197h。

| Abstract: | The climate tendency rate,sequence correlation coefficient and accumulative anomaly were adopted to analyze data of temperature,light and rainfall in Shenyang during 1951-2008. The results indicated that temperature showed obvious increase trend,while sunshine showed decrease trend,rainfall had no obvious variation; the temperature trend improved 1.4 ℃,1980 was jump point and temperature before and after the year increased 0.8 ℃; winter half year was the main body of temperature increasing,total quantity of heat increased 290 ℃; sunshine hours trend decreased 320 h,1982 was the jump point and sunshine hours before and after the year decreased 197 h. |
