huracanpy.trackswhere

huracanpy.trackswhere(tracks, track_ids, condition)

Subset tracks that verify a condition.

e.g select all tracks that are solely in the Northern hemisphere:

>>> tracks_subset = huracanpy.trackswhere(
>>>     tracks, tracks.track_id, lambda x: (x.lat > 0).all()
>>> )

e.g. select all tracks that are category 2 at least once in their lifetime:

>>> track_subset = huracanpy.trackswhere(
    tracks, tracks.track_id, lambda track: track.pressure_category.max() >= 2
    )

Parameters:

• tracks (xarray.Dataset)

• track_ids (xarray.DataArray) – The track_ids corresponding to the tracks Dataset

• condition (callable) – A function that takes an xarray.Dataset of an individual track and returns True or False

Returns:

A dataset with the subset of tracks from the input that match the given criteria

Return type:

xarray.Dataset
