Sea-ice feedbacks influence the isotopic signature of Greenland Ice Sheet elevation changes: Last Interglacial HadCM3 simulations [PDF]

Climate of the Past, 2020
Abstract. Changes in the Greenland ice sheet (GIS) affect global sea level. Greenland stable water isotope (δ18O) records from ice cores offer information on past changes in the surface of the GIS. Here, we use the isotope-enabled HadCM3 climate model to simulate a set of Last Interglacial (LIG) idealised GIS surface elevation change scenarios focusing

Terrestrial biosphere changes over the last 120 kyr [PDF]

Climate of the Past, 2016
A new global synthesis and biomization of long (> 40 kyr) pollen-data records is presented and used with simulations from the HadCM3 and FAMOUS climate models and the BIOME4 vegetation model to analyse the dynamics of the global terrestrial biosphere ...

A comparative analysis of projected impacts of climate change on river runoff from global and catchment-scale hydrological models [PDF]

, 2010
We present a comparative analysis of projected impacts of climate change on river runoff from two types of distributed hydrological model, a global hydrological model (GHM) and catchment-scale hydrological models (CHM).

Impact of Model Tuning on Simulated Mid‐Pliocene Warming

Paleoceanography and Paleoclimatology, Volume 40, Issue 4, April 2025.
Abstract A tuned version of HadCM3 (HadCM3t) is used to simulate the climate of the mid‐Pliocene warm period (mPWP) and is compared with the original untuned version of HadCM3 (HadCM3u). After the tuning, HadCM3t performs as well as HadCM3u in simulating the preindustrial climate, but aligns better with the reconstructed mPWP sea surface temperature ...

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 ...

Multidecadal to Centennial Variability of the AMOC: HadCM3 and a Perturbed Physics Ensemble

Journal of Climate, 2013
AbstractMultidecadal to centennial variability of the Atlantic meridional overturning circulation (AMOC) is investigated in a multi-thousand-year simulation of the third version of the Hadley Centre Coupled Model (HadCM3) and in an ensemble of general circulation models (GCMs) based on HadCM3 with perturbed physics.

Complex networks in climate dynamics - Comparing linear and nonlinear network construction methods

, 2009
Complex network theory provides a powerful framework to statistically investigate the topology of local and non-local statistical interrelationships, i.e. teleconnections, in the climate system.

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.

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 ...
