3D Atmospheric Imprint of Mesoscale Eddies Driven by the Thermal Feedback in the Gulf Stream Region

Abstract The 3D imprint of mesoscale ocean eddies on the overlying atmosphere is investigated using coupled ocean‐atmosphere high‐resolution simulation of the Gulf Stream region, distinguishing cyclones and anticyclones. Sea surface temperature (SST) anomalies are predominantly w...

Efficient ensemble estimation using an MCMC sampler: a reconstruction of the Mediterranean low-frequency variability combining observed and simulated sea level

Abstract. The skill of climate projections depends on the ability of models to reproduce the long-term and low-frequency variability of the system. It is thus important that low-frequency model statistics can be checked against observations. In this paper, a method is proposed to...

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...
