| 摘 要： | 分析了集宁地区1971-2010年平均气温、最高气温、最低气温的气候变化趋势和特征,结果表明,近40a集宁地区增温显著,平均气温的增温速率超过全国以及内蒙古平均水平,且呈非对称性增温,表现在最低气温增温早、速率大,突变分析也证明了这一点。另外,通过小波系数实部分析,集宁地区的近40a平均气温以及最高、最低气温变化均以准10a周期震荡为主。

| Abstract: | The average temperature, highest temperature, lowest temperature of climate trends and characteristics in Jining area from 1971-2010 was analyzed in this paper, the results showed that the warming was significant between 40 years, the rate of average temperature increasing more than the national and Inner Mongolia average level, and showed the asymmetric warming, the lowest temperature increasing early at high rate, and mutation analysis also proved that. In addition, through the wavelet coefficients of real component analysis, the average temperature and the highest and lowest temperature changes in Jining area of nearly 40 years were mainly at tO years cyclical swings. |
