| 摘 要： | 将５００ｈＰａ候平均高度、８５０ｈＰａ候平均气温和海平面气压３个常规气象场进行车贝雪夫展开，以更好地表征各场的主要特征，并浓缩了资料量。以车贝雪夫展开系数和前期基础温度作为预报因子，建立了冬半年全国４０个站点的旬平均气温距平的客观预报方程。结果表明，这种预报方法在冬半年的温度业务预报中有较好的参考价值，并讨论了各层要素与冬半年温度的相关性。

| Abstract: | The routine meteorological fields were expanded by use Chebyshev Polynomials.The coefficients of them could represent the main characteristics of meteorological fields.Using them as factors,the forecast equations for dekad temperature abnormal of China in winter were established.The result indicated that this method was useful to the forecast of temperature abnormal.On the other hand,the relativity between each level data and temperature was discussed. |

| Keywords: | Chebyshev Expansion temperature abnormal of dekad objective forecast |
