huracanpy.calc.rate

huracanpy.calc.rate(var, time, track_ids=None, centering='forward')

Compute rate of change of var, without including differences between the end and start of different tracks

Parameters:

• var (xarray.DataArray) – The variable used to calculate the rate

• time (xarray.DataArray) – Time at each point

• track_ids (array_like, optional) – Track ID at each point

• centering (str, optional) –

  • “forward” gives the rate based on the track point and the following track point. The last point of each track will be NaN

  • ”backward” gives the rate based on the track point and the previous track point. The first point of each track will be NaN

  • ”centre” gives the rate based on the centred difference of track points. The first and last points of each track will be NaN

  • ”adaptive” gives the same as centred, but fills in the first point of each track with the forward difference, and the last point of each track with the backward difference

Return type:

xarray.DataArray
