for reference, here's the MCVE: ```python import xarray as xr

ds = xr.tutorial.open_dataset("air_temperature") n = 3

window_size = {name: n for name in ["lat", "lon"]} window = ds.rolling(window_size, center=True) peak_min = window.argmin() peak_max = window.argmax() ```

As far as I can tell, the reason is that np.argmin does not support more than one axis (the actual call is here).

We could try to work around this by wrapping argmin and argmax in a function that ravels / unravels the reduce dimensions.
