oocgcm.core.grids.generic_2d_grid.horizontal_laplacian

generic_2d_grid.horizontal_laplacian(scalararray)

Return the horizontal laplacian of a scalar field at t-points.

Parameters:

scalararray : xarray.DataArray

xarray of a scalar variable defined at grid_location=’t’

Returns:

scalararray : xarray.DataArray

xarray of laplacian defined at grid_location=’t’

Notes

Compute the laplacian as the divergence of the gradient.
