Take a dask-backed array: a = xarray.DataArray(dask.array.random.random(100 * 2**30, chunks=2**20)) This works: b = xarray.ufuncs.maximum(a, 0) This will cripple your computer and force you to reboot: b = xarray.ufuncs.maximum(0, a)

In the second case, xarray.ufuncs.maximum is resolving the dask array - in other wods, it's doing numpy.maximum(0, a.values)
