摘要
为了得出近50年来普兰店市气温变化的特点及其规律,利用普兰店市1961—2010年的气温资料,并使用小波分析、线性趋势分析以及其他数据处理、分析等方法进行分析研究。结果表明：普兰店年、四季的气温分别存在每10年0.24℃、0.22℃、0.13℃、0.24℃和0.41℃的升温趋势。普兰店市年平均气温存在2-6年的震荡性周期变化特征,春、秋2季存在5-8年的震荡周期,夏、冬2季气温的震荡周期分别为2-4年和3-7年,其中3年、4年周期分别通过检验。
Based on the monthly mean temperature in Pulandian City from 1961 to 2010, the authors used linear trend estimations and wavelet analysis to explore the characteristics of temperature changes in Pulandian. The results showed that an increasing tendency existed in the explored time domain. Respectively,the tendency coefficients were 0.24℃/10 a, 0.22℃/10 a, 0.13℃/10 a, 0.24℃/10 a and 0.41℃/10 a for year andthe four seasons. The annual mean temperature had a oscillation period of 2-6 a and spring and autumn had aoscillation period of 5-8 a. Both summer and winter temperature displayed a prominent period of 3-4 a, andthe oscillation period of summer and winter was 2-4 a and 3-7 a, respectively.
