The overturning circulation in the Indian Ocean with an analogy to that in the South China Sea

overturning circulation,seasonal variability

The South China Sea (SCS) meridional overturning circulation (MOC) experiences seasonal reversal (Zhu et al., 2015). Drawing parallels with the SCS, the Indian Ocean emerges as a pertinent reference due to its comparable dynamics and forcing, including monsoon impact and the absence of deep-water formation. Notably, the Indian Ocean MOC has been associated with a basinwide adiabatic water redistribution process (Han, 2021), suggesting a potential link to the variability of the SCS MOC. In this presentation, we delve into the overturning dynamics of the Indian Ocean MOC, offering insights into its capacity to elucidate the variability of SCS MOC and its implications on meridional heat transport.
