def is_triangular(self, var):
        """
        Test if a variable is on a triangular grid

        This method first checks the `grid_type` attribute of the variable (if
        existent) whether it is equal to ``"unstructered"``, then it checks
        whether the bounds are not two-dimensional.

        Parameters
        ----------
        var: xarray.Variable or xarray.DataArray
            The variable to check

        Returns
        -------
        bool
            True, if the grid is triangular, else False"""
