  abstract = {{T}he characterization of yearly drought events represents a key information for conducting impact assessments and forecasting future threats, and usually relies on a single index of duration or severity. {M}ostly based on daily soil or atmospheric water balances, the derivation of key drought facets is not yet standardized or embedded in a single tool, thus limiting intercomparisons between studies. {W}e developed {DFEAT} as a fully-automated tool designed to characterize yearly drought features, based on any simulated/observed/remotely sensed soil water content time series. {W}e provide here an application assessment performed with the {K}eetch-{B}yram {D}rought {I}ndex ({KBDI}) as a standard daily soil water model over a 60-year period and covering the {M}editerranean aridity gradient in {L}ebanon ({M}iddle-{E}ast) experiencing humid to semi-arid climate conditions. {W}e computed and tested 19 drought features related to duration, severity, onset, offset, drying and wetting rates, driest peak day, and rainfall pulses across three soil water desiccation thresholds. {F}or our study area, we revealed the uncorrelated specificities of 6 features, allowing to regionally discriminate between mountainous {M}editerranean climate experiencing shorter drought duration (45 days), later onset ({D}ay of the {Y}ear = 198), less rainfall pulses intensities (3.35 mm), and slower drying (1.68 mm/day) and wetting (-2.72 mm/day) rates, but similar offset date ({D}ay of the {Y}ear = 356) compared to the coast. {DFEAT} also captured regions with prolonged {M}ulti-{Y}ear {D}roughts not fully refilling field capacity under arid bioclimate reaching up to 22 years. {W}e demonstrate here the applicability of {DFEAT} across water-limited bioclimates and the non-correlation between drought features with contrasted agro-ecological impacts.},
