Close relationships are found existing among seven strong autoteleconnections of the January SST over the globe. Of them the most significant is the ‘Indian-western Pacific-eastern Pacific-Atlantic’ zonal teleconnection at equatorial latitudes marked by the mode sign of + - -.A meridional and zonal positive correlation exists between the mid-latitude and western equatorial Pacific and between the latter and mid-latitude Atlantic, respectively. Temporal analysis indicates that the occurence of the equatorial zonal teleconnection type agrees with that of the EI Nino event and the anomalous SIO to the extent that it can be used to describe their appearance objectively and quantitatively, and to interpret the relationships among the annual anomalies in the strengthof the tropical Walker and Hadley cells, and the western Pacific sub-tropical high.Results can be an aid to understanding the low-latitude large-scale air-sea interaction.
