Changes in Atmospheric Convection Over the Indo‐Pacific Warm Pool and Coupled IOD and ENSO Patterns During the Last Glacial Maximum

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract This study investigates how the convection over the Indo‐Pacific Warm Pool responds to the Last Glacial Maximum conditions. Paleoproductivity records that can indicate seasonal wind dynamics are combined with modeling data. Seasonal southeasterly and northeasterly winds off Sumatra are both strengthened, meanwhile, anomalous westerly winds ...

Atmospheric and Oceanic Pathways Drive Separate Modes of Southern Hemisphere Climate in Simulations of Spontaneous Dansgaard‐Oeschger‐Type Oscillations

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract Dansgaard‐Oeschger (DO) events are a dominant mode of millennial‐scale climate variability during the last glacial period with most pronounced impacts in the North Atlantic region. In Antarctica, they manifest primarily as a muted and phase‐shifted temperature signal, but recent studies suggest an additional in‐phase component.

Progress in paleoclimate modeling [PDF]

, 2006
International audienceThis paper briefly surveys areas of paleoclimate modeling notable for recent progress. New ideas, including hypotheses giving a pivotal role to sea ice, have revitalized the low-order models used to simulate the time evolution of ...

Antarctic Water Stable Isotopes in the Global Atmospheric Model LMDZ6: From Climatology to Boundary Layer Processes

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.
Abstract Observations of water stable isotopes in Antarctic surface snow, precipitation and water vapor are key for improving our understanding of the atmospheric water cycle and past climate reconstructions from ice cores. In this study, we use isotopic observations in Antarctica to assess the skill of the isotope‐enabled atmospheric general ...

Approche par modélisation pluie-débit de la connaissance régionale de la ressource en eau : application au haut bassin du fleuve Sénégal

Physio-Géo, 2012
Today water resources management is crucial at various scales (local, regional, national and international). This management is encouraged by the extreme hydrological events (droughts or floods) that can have dramatic consequences on human, economic and ...

Altitude dependence of atmospheric temperature trends: Climate models versus observation [PDF]

, 2004
As a consequence of greenhouse forcing, all state of the art general circulation models predict a positive temperature trend that is greater for the troposphere than the surface.

Future MJO Change and Its Impact on Extreme Precipitation and Temperature Over the Western US in CMIP6

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.
Abstract The Madden‐Julian oscillation (MJO) has remarkable impacts on global weather and climate systems. This study examines the future changes in MJO projected by 23 Coupled Model Intercomparison Project Phase 6 (CMIP6) models that produce a realistic MJO propagation in their historical runs. Results from the multi‐model mean show a ∼17% increase in

Climate variability and its impacts on runoff in the Kosasthaliyar sub-basin, India

Earth Sciences Research Journal, 2014
Research on the effect of climate variability/climate change on rainfall-runoff modeling is limited in humid tropical regions. Climate change has implications beyond the water resources sector, such as effects on agriculture and fisheries.
