Large-scale climate drivers of extreme compound events in the Amazon from interannual to long-term timescales (1982–2024)

Abstract Over recent decades Amazonia has experienced a marked intensification of floods and droughts. The record-breaking 2023–2024 drought, characterized by exceptional heat and dryness, motivates a closer analysis of compound extremes and their large-scale drivers. This study...

Explaining monthly precipitation anomalies in northwestern South America by integrating vertical dynamics and energetics

Abstract. In dynamically limited environments such as the coastal Northwestern South America (NWSA), thermodynamic instability (ΔT) alone is insufficient to autonomously trigger deep convection due to persistent background subsidence. The Buoyancy Work Rate (BWR) addresses this b...

Characterization of the ecological impacts of prescribed fire in South America: a review

Prescribed fire has been shown to offer substantial benefits to both human populations and ecosystems, but it can also cause environmental harm, such as reduced air quality and negative impacts on sensitive species. To support the appropriate use of prescribed fire, stakeholders...
