abstract = "The wind stress is a measure of momentum transfer due to the
relative motion between the atmosphere and the ocean. This study
aims to investigate the anomalous pattern of atmospheric and
oceanic circulations due to 50% increase in the wind stress over
the equatorial region and the Southern Ocean. In this paper we use
a coupled climate model of intermediate complexity (SPEEDO). The
results show that the intensification of equatorial wind stress
causes a decrease in sea surface temperature in the tropical
region due to increased upwelling and evaporative cooling. On the
other hand, the intensification of wind stress over the Southern
Ocean induces a regional increase in the air and sea surface
temperatures which in turn leads to a reduction in Antarctic sea
ice thickness. This occurs in association with changes in the
global thermohaline circulation strengthening the rate of
Antarctic Bottom Water formation and a weakening of the North
Atlantic Deep Water. Moreover, changes in the Southern Hemisphere
thermal gradient lead to modified atmospheric and oceanic heat
transports reducing the storm tracks and baroclinic activity.",
