| 摘 要： | 采用EOF方法分析辽宁省48年极端气温时空分布规律。第一特征向量空间分布指出全省极端气温变化具有同步性,第二和第三特征向量分别代表地理纬度和地形因素对极端温度分布的影响。第一时间系数的正负变化则分别反映了全省极端气温随时间的演变规律,序列均呈波动性上升趋势。

| Abstract: | The temporal and spatial distribution laws of extreme temperature in Liaoning province for 48 years were analyzed by using EOF method.The spatial distribution of the1st eigenvector pointed out that the changes of extreme temperature in the whole province had synchronism.The 2nd and 3rd eigenvector represented the effects of latitude and landform on extreme temperature distribution resp.The positive and negative changes of the 1st time coefficient reflected the the evolvement laws of extreme temperature in whole province with time.And all the sequences showed the fluctuant increasing trend. |
