Based on 1951～1985 winter monthly mean geopotential height data at 700、500and 100 hPa of the Northern Hemisphere,analysis is done of the anomalies of circulations inrelation to the five teleconnections proposed by Wallace et al.(1981),together with the study of their properties. Results show that these anomalies have an equivalent barotropic structurein the mid to lower troposphere, and become weakened and disappear in the upper troposphere and that anomalies of some teleconnections.e.g.,EU and PNA,have a noticeable relation to each other,with the abnormality persisting for the order of one month for the principal teleconnection patterns.
