Review of global climate models used for drought assessment and forecasting

Key Points

• Drought assessment relies heavily on predictive accuracy and temporal resolution of climate models, influencing decision-making.
• Key climate models evaluated include those with varying spatial resolution and forecast capabilities, providing insights into drought variability.
• Observational analysis of model outputs reveals significant gaps in accuracy, necessitating improved methodologies for predicting droughts.
• Highlights the urgent need for a unified framework to enhance cross-model comparisons and ensure robust forecasting capabilities.
