ABSTRACT

Sea surface height (SSH) in the Southern Indian Ocean (SIO) and Antarctic circumpolar current (ACC) regions have been studied using the Princeton ocean model (POM). POM has also been used to simulate volume transport and heat transport through Indonesian throughflow (ITF). SST, SSH, and heat flux in SIO and ACC regions have been successfully simulated using the modular ocean model (MOM3). Using chaos dynamics, strange attractors have been identified for southern oscillations (SO) and Pacific Decadal Oscillations (PDO), but not in North Atlantic oscillations (NAO) and Antarctic oscillations (AO). Semtner and Winton's three-layer sea ice models have been successfully implemented to simulate sea ice thickness and snow surface temperatures for polar regions. Temperature, geo-potential height, and horizontal wind vectors have been predicted around Indian Antarctic Station Maitri using polar MM5. SST anomalies in SIO and ACC regions have also been simulated using artificial neural networks (ANNs).
