Simulation and analysis of marine hydrodynamics based on the El Niño scenario by M. Ikhwan, R. Wafdan, Y. Haditiar, M. Ramli, Z. Muchlisin, S. Rizal

“…CONCLUSION: Strong winds could mix water masses up to a depth of 100 meters, implying that during an ideal El Niño, the stratification of the water column is influenced by strong winds. The eastern domain has the highest sea level amplitude, resulting in perfect mixing up to a depth of 100 m, while wind effect is negligible in the lower layers. …”
