Sensitivity experiments with intraseasonal wind forcing selectively applied in the equatorial region, Bay of Bengal, and Arabian Sea show that a large part of the basin-scale sea level variations are driven by zonal wind fluctuations along the equator. Within the NIO coastal waveguide, the contribution of remote equatorial forcing decreases from similar to 80-90% in the Andaman Sea to similar to 50% northeast of Sri Lanka and then increases to similar to 60-70% along the west coast of India. During the southwest monsoon, intraseasonal wind variations become stronger over the NIO, resulting in a larger contribution of local wind forcing to sea level variability along the west (up to 60%) and east (up to 40%) coasts of India. specialized northern Indian Ocean intraseasonal sea level variability equatorial waveguide coastal waveguide local and remote forcing OCEAN INDIEN ZONE EQUATORIALE 032 020 40 21 5740-5744 2013 0094-8276 https://www.documentation.ird.fr/hor/fdi:010061400 10.1002/2013gl058312 0094-8276 [F B010061400] https://www.documentation.ird.fr/hor/fdi:010061400 https://www.documentation.ird.fr/intranet/publi/2014/01/010061400.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-02-05 2017-08-23 fdi:010061400 fre
