Ilana Wainer earned her Ph.D. from Pennsylvania State University in 1992. She is currently a Professor in the Department of Physical Oceanography, at the University of Sao Paulo, Brazil. Wainers research focuses on physical oceanography effects on climate and modeling these effects. Specifically, she has worked on current and paleoclimate of the southeastern Brazilian shelf, Antarctic sea ice, effects of tropical variability on the North Atlantic Oscillation, and representation of Southern Ocean processes (subduction, glacial cycles, precipitation, ocean-atmosphere interactions) in global climate models. More recently she has been working in translating the large-scale climate information into local actionable science for the Southwest Atlantic coastal region. Wainer has served on the international steering committees of many national and international steering committees for climate and ocean observation programs. She serves on the SCOR Executive Committee as a vice-president. (Source: Lattes Curriculum)

OCOD-TSA research project aims at improving our understanding of the mechanisms underlying Tropical and South Atlantic Sea Surface Temperatures (SSTs) low frequency variability and sensitivity to natural (i.e. solar, orbital, volcanoes) and anthropogenic forcings (i.e. greenhouse gases) and its influence on hydro-climates of surrounding regions. Tropical and South Atlantic SST may have va…
Studies on the geological record of the Antarctic Intermediate Water in the Southwest Atlantic are quite scarce, despite its fundamental role in the southern circulation. This water mass, transported by the Subtropical Gyre, undergoes a bifurcation when reaching the South Atlantic's west margin, forming the Santos Bifurcation.In this project, we propose to study the Santos Bifurcation at …
The purpose of this visit is to investigate in details the connections between hydroclimate in northern Africa and South America during the last Green Sahara period (GSP; 11,000 - 5,000 years ago). In particular, our previous collaborations have shown the large impacts that the strengthening of West African Monsoon (WAM) can have on the Amazon (drying) and south America in general (Gorens…
The Paleoclimate Modeling Intercomparison Project/Coupled Model Intercomparison Project (PMIP/CMIP) Mid-Holocene (MH, 6,000 yr BP) experiment considers the orbital forcing as the main driver of the climate during this period. However, the PMIP/CMIP models are not currently able to reproduce the strengthening/northward expansion of the West African Monsoon during the Green Sahara. Furtherm…
The South American Monsoon (SAMS) has a direct impact on the hydrology of the region and is influenced by the variability of surface temperatures in the South Atlantic. This ocean is indeedone of the most important sources of moisture flow that feeds rainfalls in South America. This monsoon flux also depends on the land-sea gradient to establish and evolve. Due to their impacton the net s…

The Atlantic Subtropical Cells (STCs) are shallow overturning circulations that connect subtropical subduction regions to equatorial upwelling zones. They are primarily driven by wind stress but are also influenced by interactions with the Atlantic Meridional Overturning Circulation (AMOC) and may modulate sea surface temperature (SST) variability (i.e. Atlantic Niño). Their variability, …
Human activities are highly dependent on climatic conditions. Rainfall in particular is crucial for agriculture and availability of water resources. Nonetheless, extreme rainfall events, as well as prolonged periods with little or no rainfall, may have deep economic and societal impacts and lead to the loss of lives. In the Tropics, the Hadley circulation plays a key role in controlling p…
The South Atlantic western boundary current system is strategically embedded in the general framework of the large-scale ocean circulation. The anticyclonic South Atlantic subtropical gyre (SASG) provides the means by which the upper-limb of the Atlantic Meridional Overturning Circulation (AMOC) is advected northward, up to the point where the flow at its Northern boundary (represented by…
Large volcanic eruptions can affect the global climate through changes in atmospheric and ocean circulation. Understanding the influence of volcanic eruptions on the hydroclimate over monsoon regions is of great scientific and social importance. The South America Monsoon System (SAMS) is the most important climatic feature of the continent. Both the Intertropical and the South Atlantic wi…
The coldest places on Earth, where most of the water is found in its solid state, constitute the cryosphere. These places work like "natural thermometers" for the planet and are determinants for its equilibrium. Nonetheless, the planet and, consequently, the cryosphere are subject to change according to natural and human ecological variations, the latter being responsible for accelerating…
Considering the need to understand the role of the ocean in climate change projections and the need for diagnosis and evaluation of these projections to account for internal variability, we will investigate the pathways, which compose the upper limb of the Meridional Overturning Circulation in the South Atlantic sector. This region is the focus of the Brazilian contribution for the projec…

This project proposes to investigate the paleoceanographic evolution of the western South Atlantic circulation with focus on the past 2,000 years (2k), at the LOCEAN-IPSL – Sorbonne Universit ´ e, under the supervision of Dr. Myriam Khodri, who is currently involved in past2k PMIP4-CMIP6 simulations, investigating the influence of external forcings on climate variability and change. Our g…
The associated PhD project focuses on the impact of great volcanic eruptions on the dominant mechanisms of seasonal-to-interdecadal variability of the Atlantic Subtropical Cells (STC), its connection with the leading modes of Atlantic Tropical sea surface temperature (SST) variability and, therefore, how the South American hydroclimate responds to these processes. The Last Millennium (LM)…
In the Tropics, the Hadley circulation plays a key role in controlling precipitation patterns, since it is related to the position of the ITCZ, which is also a main component of the South America Monsoon System (SAMS). The position of the ITCZ over the ocean is locked to the sea surface temperature patterns and the net northward heat transport in the Atlantic ocean, by the meridional over…
