介绍了对西风带上部 112 例阻塞行动的半统计研究结果；确定最常发生的区域、特征运动和持续时间以及阻塞活动的季节性和年度趋势。说明了与欧洲上空阻塞相关的区域降水和平均地表温度异常，并与高空强纬向流产生的降水和平均地表温度异常进行了比较。讨论了阻塞活动的变化对欧洲气候趋势产生的影响。讨论了阻塞作用对斯堪的纳维亚冰川作用的影响以及阻塞在冰河时代气候循环中所起作用的某些迹象。 DOI：10.1111/j.2153-3490.1950.tb00339.x
The results of a semi-statistical study of 112 cases of blocking action in the upper westerlies are presented; areas of most frequent occurrence, characteristic movement and persistence, and seasonal and yearly trends of blocking activity are determined. The regional precipitation and mean surface-temperature anomalies associated with blocking over Europe are illustrated and compared with those produced by strong zonal flow aloft. The effects produced by variations in blocking activity upon European climatic trends are discussed. The influence of blocking action upon Scandinavian glaciation and certain indications as to the role played by blocking in an ice-age climatic cycle are discussed.
