The theory of point vortices is used to explain the interaction of a surface vortex with subsurface vortices in the framework of a three-layer quasigeostrophic model. Theory and numerical experiments are used to calculate the interaction between one surface and one subsurface vortex. Then. the configuration with one surface vortex and two subsurface vortices of equal and opposite vort... https://www.chiggate.com/shades-eq-09gi-hamptons-supply/
