A field of barotropic background currents (BC) in the Gulf of California is constructed numerically. The definition of BC used here is based on suppositions about (i) the horizontal homogenization of potential vorticity in large-scale gyres. and (ii) the tendency of a current structure to evolve to a state with a minimum of system mechanical energy. In the barotropic case here. https://www.countryscenesaddleryandpetsuppliers.shop/product-category/trailer-tie-bungee/
