get_perturbation#
- metpy.calc.get_perturbation(ts, axis=- 1)#
Compute the perturbation from the mean of a time series.
- Parameters
ts (array_like) – The time series from which you wish to find the perturbation time series (perturbation from the mean).
axis (int) – The index of the time axis. Default is -1
- Returns
array_like – The perturbation time series.
Notes
The perturbation time series produced by this function is defined as the perturbations about the mean:
\[x(t)^{\prime} = x(t) - \overline{x(t)}\]
