Heat spell maximum length.

The longest heat spell of a period. A heat spell occurs when rolling averages of daily minimum and maximum temperatures exceed given thresholds for a number of days.

Units:

  • heat_spell_max_length: days

This function wraps xclim.indicators.atmos.heat_spell_max_length.

Parameters:

  • tasmin (xarray.DataArray | str) – Minimum surface temperature.

  • tasmax (xarray.DataArray | str) – Maximum surface temperature.

  • window (int) – Minimum length of a spell.

  • win_reducer (Literal[``’min’, ``'max', 'sum', 'mean']) – Reduction along the spell length to compute the spell value. Note that this does not matter when window is 1.

  • freq (str) – Resampling frequency.

  • min_gap (int) – The shortest possible gap between two spells. Spells closer than this are merged by assigning the gap steps to the merged spell.

  • resample_before_rl (bool) – Determines if the resampling should take place before or after the run length encoding (or a similar algorithm) is applied to runs.

  • thresh_tasmin (Any) – Threshold for tasmin

  • thresh_tasmax (Any) – Threshold for tasmax

  • ds (xarray.Dataset | Any) – Input dataset.

  • **kwargs (Any) – Additional keyword arguments.

Returns:

The computed index.

Return type:

Any
