説明

<jats:p>Satellite observations reveal a substantial weakening of the southeasterly trade wind over the South Indian Ocean during 1992–2000 and a resultant slowdown of the shallow meridional overturning circulation in this Ocean. The estimated rate of the slowdown of this circulation, 6.8 ± 1.4 × 10<jats:sup>6</jats:sup> m<jats:sup>3</jats:sup>/s over the 9‐year period, is nearly 70% of the mean strength of this circulation. Such a change has important implications to upper‐ocean heat content and decadal climate variability of the Indian Ocean, as well as to the ecosystem and air‐sea exchange of CO<jats:sub>2</jats:sub> in the region.</jats:p>
