北半球超长波的振动与冷空气活动

The relationship between the oscillation of ultra-long waves of the northern hemi-sphere and the outbreak of cold air

  • 摘要: 本文对1972—1976年冬半年北半球500mb 5天平均高度资料进行了波谱分析。讨论了超长波振动与强冷空气活动的关系。发现超长波的振动明显地随纬度而改变,高纬和极区超长波活动显著,当高低不同纬度地区超长波出现“共振”使行星尺度的斜槽发展时,则对应出现强冷空气的爆发。还讨论了超长波波型、振幅、位相的转换与冷空气爆发的关系。
