Research

My present research focuses on theoretical modeling of currents' retroflection from slanted coasts and near the corners of coastlines. On the basis of this, I consider the features of rings' shedding from Agulhas current during austral summers and winters, as well as behavior of Agulhas retroflection during glacial periods. This is very important for understanding the climate dynamics in Atlantic because the rings are responsible for transporting most of the water masses from the Indian Ocean. The developed model allows us to give explanations of similarity and difference in rings' shedding by other retroflecting currents, such as Brazil current, North Brazil current, and East Australian current.

Also, I work with the Aguhas current numerical model developed in LANL. My study concerns possibilities of appearance/disappearance of "retroflection paradox" and "vorticity paradox" as limits on the branches of steady states in numerics, depending on viscosity, wind forcing, and boundary conditions.
