Impact of Trans-Atlantic-Pacific Ocean Dipole–like pattern on summer precipitation variability over West Africa

Atmospheric and Oceanic Science Letters, 2018
Recent findings indicate that rainfall variability over West Africa is characterized by more positive anomalies in the last four decades. The authors demonstrate that the recent interannual rainfall variability is linked to an air–sea phenomenon that ...

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Southern African orography impacts on low clouds and the Atlantic ITCZ in a coupled model

Geophysical Research Letters, 2017
We examine the influence of southern African orography on the Namibian stratocumulus deck, the South Atlantic ocean‐to‐atmosphere energy transport, and the Intertropical Convergence Zone (ITCZ), using an atmosphere‐only model and a coupled atmosphere ...

Atmosphere drives recent interannual variability of the Atlantic meridional overturning circulation at 26.5°N [PDF]

, 2013
The RAPID-MOCHA array has observed the Atlantic Meridional overturning circulation (AMOC) at 26.5°N since 2004. During 2009/2010, there was a transient 30% weakening of the AMOC driven by anomalies in geostrophic and Ekman transports.

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

International Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

Seasonal Re-emergence of Sea Surface Temperature Anomalies in the North Atlantic: An Observational and Ocean Model Study

, 2013
The aim of this thesis is to provide a more comprehensive and dynamic understanding of sea surface temperature anomaly (SSTA) re-emergence in the North Atlantic, by (a) re-evaluating the utility of re-emergence for sea surface temperature (SST ...

Monitoring the Amazon River plume from satellite observations

GIScience & Remote Sensing
Most of our knowledge about the Amazon River plume is limited from the field experiments or modeling due to various challenges for satellite remote sensing, i.e., constant cloud coverage, atmospheric correction, and difficulties to differentiate the ...

Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence

International Journal of Climatology, EarlyView.
Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

Mare Occidentale

Terra Brasilis, 2007
Since the discovery of America and throughout the sixteenth century, one of the main concerns of cartographers was to draw with increasing precision the coasts of continental America and the Atlantic islands.
