打破历史极值可能性不大 Break history extreme unlikely

　　中国气象局首席预报员张芳华解释，这次寒潮影响范围较大，除了整个北方和中东部大部分地区之外，高原地区也有一些影响。这次寒潮之所以这么强劲，是来自北极和西伯利亚寒冷地区的冷空气在新疆地区积聚，在高空西北气流的影响下开始东移。在22日之前，冷空气是分股南下的形式，22日之后便整体东移南下发展，因此影响较大。

The China meteorological administration chief forecaster ZhangFangHua interpretation,The cold wave impact range is very large,In addition to the north and most parts of east-central outside,Plateau area also have some effect.The cold wave is so strong,Is from the North Pole and Siberian cold area of cold air in the xinjiang region accumulation,In the upper northwest flow under the influence of a new start.In the 22 before,Cold air is split in the form of down,22 and the overall development of a new after south,So greatly influenced.
