Teleconnected influence of the boreal winter Antarctic Oscillation on the Somali Jet: Bridging role of sea surface temperature in southern high and middle latitudes

The teleconnection impact of the boreal winter Antarctic Oscillation (AAO) on the Somali Jet (SMJ) intensity in the following spring and summer is examined in this paper. The variability of the boreal winter AAO is positively related to the SMJ intensity in both spring and summer. The analyses show that the SST in southern high and middle latitudes seems to serve as a bridge linking these two systems. When the AAO is in strong positive phase, SST over the Southern Ocean cools in the high latitudes and warms in the middle latitudes, which persists into summer; however, the variability of SST in southern high and middle latitudes is also closely correlated to SMJ intensity.
