Ground/satellite observations and atmospheric modeling of dust storms originating in the high Puna‐Altiplano deserts (South America): Implications for the interpretation of paleo‐climatic archives
(American Geophysical Union, 2013-05)
This study provides a detailed description of the sources, transport, dispersion, and deposition of two major dust events originating from the high‐altitude subtropical Puna‐Altiplano Plateau (15?26°S; 65?69°W) in South ...
The PMIP4 contribution to CMIP6-Part 4: Scientific objectives and experimental design of the PMIP4-CMIP6 Last Glacial Maximum experiments and PMIP4 sensitivity experiments
(2017)
The Last Glacial Maximum (LGM, 21 000 years ago) is one of the suite of paleoclimate simulations included in the current phase of the Coupled Model Intercomparison Project (CMIP6). It is an interval when insolation was ...
Atmospheric circulation changes and neoglacial conditions in the Southern Hemisphere mid-latitudes: Insights from PMIP2 simulations at 6 kyr
(2011)
Glacial geologic studies in the Southern Hemisphere (SH) mid-latitudes (40-54°S) indicate renewed glacial activity in southern South America (Patagonia) and New Zealand's (NZ) South Island starting at ~7 kyr, the so-called ...
Climatic controls of Holocene fire patterns in southern South America
(2007)
Holocene fire-climate-vegetation linkages are mostly understood at individual sites by comparing charcoal and pollen records with other paleoenvironmental proxy and model simulations. This scale of reconstruction often ...
Effect of changing vegetation and precipitation on denudation - Part 1: Predicted vegetation composition and cover over the last 21 thousand years along the Coastal Cordillera of Chile
(Copernicus GmbH, 2018)
Vegetation is crucial for modulating rates of denudation and landscape evolution, as it stabilizes
and protects hillslopes and intercepts rainfall. Climate conditions and the atmospheric CO2 concentration, hereafter [CO2], ...
Mid-Holocene PMIP3/CMIP5 model results: Intercomparison for the South American Monsoon System
(2013-12)
The mean precipitation fields for eastern South America from eight mid-Holocene (6 ka) simulations, part of the third phase of Palaeoclimate Modeling Intercomparison Project (PMIP3) and the fifth phase of the Coupled Model ...
South American precipitation changes simulated by PMIP3/CMIP5 models during the Little Ice Age and the recent global warming period
(John Wiley & Sons Ltd, 2018-05)
Large climate variations have been detected from paleoclimatic records in some regions of South America during the last 500 years. Among them, the Altiplano and the subtropical Andes regions exhibited wetter-than-normal ...
Validating NCAR-CCSM last glacial maximum sea surface temperature in the tropical and South Atlantic with proxy-data
(ELSEVIER SCIENCE BV, 2008)
Last Glacial Maximum simulated sea surface temperature from the Paleo-Climate version of the National Center for Atmospheric Research Coupled Climate Model (NCAR-CCSM) are compared with available reconstructions and ...
Paleo±Dust: quantifying uncertainty in paleo-dust deposition across archive types
(2024)
Mineral dust aerosol concentrations in the atmosphere varied greatly on glacial–interglacial timescales. The greatest changes in global dust activity occurred in response to changes in orbital parameters (which affect dust ...
High-resolution marine data and transient simulations support orbital forcing of ENSO amplitude since the mid-Holocene
(Elsevier, 2021)
Lack of constraint on spatial and long-term temporal variability of the El Niño southern Oscillation (ENSO) and its sensitivity to external forcing limit our ability to evaluate climate models and ENSO future projections. ...
