The groups from University of São Paulo (USP) and Xi'an Jiaotong University are expert in paleoclimate reconstruction based on the speleothem stable isotope records. The joint research by these groups based in China and Brazil are highly complementary because they have produced most of speleothem records from South America, East Asia and India monsoons and when combined can bring a unique…
The South American summer monsoon brings vast amounts of precipitation to the Amazon basin, providing an important lifeline to its forest and livelihoods. However, it remains uncertain how climate change and increasing C02 levels will affect Amazonian precipitation. In this proposal we attempt to gain insight in the Amazon hydrological cycle by reconstructing its climate responses in the …
This proposal seeks funding for reconstructing climate variability and change during the past millennium (850 C.E -1850 C.E) using speleothem and tree-ring records from the South American monsoon region. The last millennium is a key period for climate reconstruction, because it allows analyzing natural climate variability in the absence of human influence. It is also a time period that in…

This postdoc proposal delves into the intricate interplay between climate dynamics, atmospheric conditions, and hydrological patterns over various temporal scales, focusing mainly on the Holocene and glacial-interglacial transitions. As global temperatures approach or surpass the critical 1.5°C threshold, significant alterations in precipitation patterns ensue, accompanied by heightened r…
The South Atlantic Convergence Zone (SACZ), characterized by a band of convective with a northwest-southeast direction, extends from the Amazon to the subtropical Atlantic, is a fundamental role in the South America rainfall distribution. Its activity is associated with most of the South American Monsoon System (SMAS) precipitation. Variations in the intensity and average position of this…
Our current understanding of the climate systems and forcings influencing past precipitation variability in South America (SA) has drastically increased over the past decades. Yet some emerging questions need greater coverage of high-resolution continental records, especially over the region influenced by the Intertropical Convergence Zone (ITCZ) in northern SA. Since differences with the…

Paleoclimate reconstructions in South America strongly rely on the interpretation of ´18O and ´13C from carbonate (´18OC, ´13CC) of speleothems. However, these registers are often affected by complex processes along atmospheric transport pathways and inside the cave system, which makes their interpretation challenging. Particularly, variations of temperature in the cave environment and in…
The Intertropical Convergence Zone (ITCZ) and the South America Monsoon System (SAMS) are the main responsible for convection over tropical region in South America. According to our previous results, the atmospheric dynamic between ITCZ and SAMS changed throughout the last millennia over Northeastern Brazil (NEB) causing climate fluctuations not expected for some regions. Results from Tra…
The Intertropical Convergence Zone (ITCZ) and the South America Monsoon System (SAMS) are the main responsible for convection over tropical region in South America. Despite previous studies have described the ITCZ variability in different time scales, as well as the SAMS, the relationship between these systems has not been tested yet for the last millennia. Our previous isotope results fo…
