对冬季冬季平流层显著变暖前后对流层状况的研究表明，这两个大气区域的发展是相互依存的。已调查的11个北半球冬季表明，平流层每两年的行为在初始增暖的位置、系统的运动方向和随后的对流层响应方面都是相似的。每隔一年，美国东部和加拿大上空的平流层就会出现仲冬暖化，1957年和1963年发表的例子就说明了这一点。在周期的交替年份中，变暖起源于中欧和东欧。在这篇文章中，重点放在了这类变暖上。每次增温前对流层环流形势相似，增温后约10天后出现海平面阻塞局面。很可能26米长的……
Abstract An investigation of tropospheric conditions before and after pronounced stratospheric midwinter warmings indicates an interdependence of developments in the two atmospheric regions. The eleven northern hemisphere winters which have been investigated show that every two years the behavior of the stratosphere is similar as regards the location of the initial warming, direction of movement of systems, and subsequent response of the troposphere. Every second year the midwinter warmings begin in the stratosphere above the eastern United States and Canada, as illustrated in the published examples from 1957 and 1963. During the alternate years of the cycle the warmings originate over central and eastern Europe. In this paper the emphasis has been placed on this type of warming. The tropospheric circulation patterns before each warming of this kind are analogous, and the warming is followed after about ten days by a blocking situation at sea level. It is likely that there is a connection between the 26-m...
