Record #176993:

Can the equatorial ocean quickly respond to Antarctic sea ice/salinity anomalies? / V.O. Ivchenko, V.B. Zalesny, M.R. Drinkwater.

Title: Can the equatorial ocean quickly respond to Antarctic sea ice/salinity anomalies? / V.O. Ivchenko, V.B. Zalesny, M.R. Drinkwater.
Author(s): Ivchenko, V. O.
Zalesny, V. B.
Drinkwater, M. R.
Date: 2004.
In: Geophysical Research Letters. (2004.), Vol. 31(15) (2004)
Abstract: Uses Institute of Numerical Mathematics model to demonstrate that signals generated by anomalies in Antarctic sea-ice cover/salinity distribution can propagate in wave-like manner in form of fast-moving barotropic Rossby waves. Such waves propagate from Drake Passage to western Pacific in only a few days. This signal is reflected at western boundary of Pacific and generates coastally trapped Kelvin wave moving equatorwards. Resulting temperature anomaly propagates northwards along western coastline to vicinity of equator and increases in amplitude with time. Anomaly in western edge of equatorial Pacific then begins to move eastward along equator as trapped equatorial wave, reaching eastern coast after 2-3 months. This process may be one possible direct mechanism by which extra-tropical ocean can induce anomalies in equatorial ocean.
