Issue Date: | 2012 | Journal: | Journal of Physical Oceanography | Abstract: | Meridional velocity, mass, and heat transport in the equatorial oceans are difficult to estimatebecause of the nonapplicability of the geostrophic balance. For this purpose a steady-state model is utilized in the equatorial Indian Ocean using NCEP wind stress and temperature and salinity data fromthe World Ocean Atlas 2005 (WOA05) and Argo. The results show a Somali Current flowing to the south during the winter monsoon carrying -11.5 ± 1.3 Sv (1 Sv [106 m3 s-1) and -12.3 ± 0.3 Sv from WOA05 and Argo, respectively. In the summer monsoon the SomaliCurrent reverses to the north transporting 16.8 ± 1.2 Sv and 19.8 ± 0.6 Sv in the WOA05and Argo results. Transitional periods are considered together and in consequence, there is not a clear Somali Current present in this period. Model results fitwith in situ measurements made around the region, although Argo data results are quite more realisticthan WOA05 data results. © 2012 American Meteorological Society. | URI: | http://hdl.handle.net/10553/72503 | ISSN: | 0022-3670 | DOI: | 10.1175/JPO-D-12-033.1 | Source: | Journal of Physical Oceanography [ISSN 0022-3670], v. 42 (12), p. 2234-2253 (Diciembre 2012) |
