北半球极涡面积、强度的季节变化及其与中国东北地区气温的关系

The seasonal variations of area and intensity of polar vortex in northern hemisphere and relationship with temperature in Northeast China

  • 摘要: 本文讨论北半球极涡面积、中心强度与全国40个台站温度的关系及它们的季节变化,并得出如下结论: 1.当第二象限(85°—175°E)极涡面积大,极涡中心位势米值高时,中国大多数站的气温偏冷,反之亦然. 2.在500百帕层冬季第一象限(5°W—85°E)极涡面积与夏季第二象限极涡面积成正相关. 3.季节的极涡中心强度是持续的. 4.在欧亚大陆的极涡面积大小的振荡分别向东—西两方向传播.
