mpas_analysis.ocean.utility.vector_cell_to_edge_isotropic(ds_mesh, zonal_cell, meridional_cell)

Compute the zonal and meridional components of a vector at edges from cell-centered components using isotropic area-weighted averaging.

Parameters:

• ds_mesh (xarray.Dataset) – MPAS mesh variables, must include: - verticesOnEdge - cellsOnVertex - kiteAreasOnVertex

• zonal_cell (xarray.DataArray) – Zonal component at cell centers (nCells,)

• meridional_cell (xarray.DataArray) – Meridional component at cell centers (nCells,)

Returns:

• zonal_edge (xarray.DataArray) – Zonal component at edges (nEdges,)

• meridional_edge (xarray.DataArray) – Meridional component at edges (nEdges,)
