A sectorized stretched gridmesh for modeling San Francisco Bay and shelf circulation

"A numerical circulation model gridmesh with stretched coordinates is developed and applied to San Francisco Bay and the adjacent shelf seaward to 50 km from Pt. Arena in the north to Pt. Sur in the south. The new mesh has variable grid widths, which are created by transforming (stretching) the x and y coordinates. The transformation of either axis can be applied in two sectors so that grid cells inside the Bay are small, and cells along the outer coast are larger. The transformed mesh is very useful because (1) it provides high resolution inside the Bay where it is needed, and (2) the larger coastal grid cells will significantly reduce computer running time."
