- 摘要:
- 大量研究数据表明全球气候正在变暖，而且近100年间变暖趋势更加明显。区域间的极端气候也频繁发生。现选取内蒙古乌尔旗汗19812011年的气象监测数据，对其从温度、降水、日照时数等方面做出变化规律的分析。结果表明：乌尔旗汗气温升高，降水量降低，日照时数增加的趋势与全球变化趋势较一致。近30年气温的增速略高于全国平均水平，尤其是1993、1994年间气温波动最明显，增幅较大，反弹剧烈。1986年、1995年、2007年降水量不足200 mm，均偏低，较为干旱。
- Abstract:
- A lot of research data showed that global climate was warming,and nearly 100 years between a warming trend was more obvious,regional climate extremes also occured frequently.Selected meteorological monitoring data,of Wuerqihan during 1981 to 2011 climate characteristics(temperature,precipitation and sunshine hours) were analyzed.The results showed that the trend of increasing temperature,decreasing precipitation,increasing number of hours of sunshine were consistent in the world.For nearly 30 years,growth of temperatures was slightly higher than the national average temperature，the temperature fluctuations were the most obvious especially between 1994 and 1993． Annual rainfall in 1986，1995 and 2007 were less than 200 mm．
