Seasonal cycle of sea level and currents along the coast of India

A framework involving long baroclinic waves, which treats the north Indian Ocean as a single dynamical entity, has been remarkably successful in simul ating the low-frequency, large-scale circulation in the ocean. It is, howev er, unable to simulate the observed seasonal, cycle of sea level along the Indian coast. The reason appears to be the absence of salinity variation in these models. The large inflow of freshwater into the:seas around India fo rces large changes in salinity, and hence, in coastal sea level.
