To evaluate how meteorological drought indices reflect streamflow deficits across diverse catchment settings and climatic conditions.
Analyzed 47 small- to medium-sized catchments in a humid-temperate Austrian climate using four meteorological drought indices reflecting different water balance components.
Assessed drought link quality and low-flow event detection using rank correlation analysis and hit-score probabilities across seasons and catchment types.
Overall rank correlations between meteorological drought indices and streamflow ranged from 0.4 to 0.8, showing significant regional variation.
Correlation was markedly stronger for summer low flows and under humid conditions where climate forcing drives streamflow drought.
Under drier conditions, predictive skill declined unless soil moisture accounting schemes were incorporated, while extensive groundwater storage and snow processes further decoupled streamflow from meteorological indices.

Implication

Regional analysis reveals strong links between meteorological drought and streamflow in temperate catchments, indicating underground storage heavily modulates drought propagation.
