South Atlantic Circulation and Variability from a Data Assimilating Model
(CRC Press - Taylor & Francis Group, 2017)
We characterize the low frequency variability of the South Atlantic circulation using 50 years of data from the SODA model. EOF analysis show that the leading modes of sea surface height anomalies (SSH) are dominated by ...
Evidencing decadal and interdecadal hydroclimatic variability over the Central Andes
(IOP Publishing, 2016-09-14)
In this study we identified a significant low frequency variability (8 to 20 years) that characterizes the hydroclimatology over the Central Andes. Decadal–interdecadal variability is related to the central-western Pacific ...
On the Wind Contribution to the Variability of Ocean Currents Over Wide Continental Shelves: A Case Study on the Northern Argentine Continental Shelf
(Blackwell Publishing, 2019-09)
The southwestern Atlantic Ocean has one of the largest and most productive continental shelves of the southern hemisphere. Despite its relevance, its circulation patterns have been largely inferred from hydrographic ...
Decadal Characterization of Indo-Pacific Ocean Subsurface Temperature Modes in SODA Reanalysis
(American Meteorological Society, 2015-04-29)
Studies of decadal-to-multidecadal ocean subsurface temperature variability are fundamental to improving the understanding of low-frequency climate signals. The present study uses the Simple Ocean Data Assimilation (SODA) ...
New insights into the biennial-to-multidecadal variability of the water level fluctuation in Lake Titicaca in the 20th century
(Frontiers Media, 2024-01-12)
The water disponibility of Lake Titicaca is important for local ecosystems, domestic water, industry, fishing, agriculture, and tourism in Peru and Bolivia. However, the water level variability in Lake Titicaca (LTWL) still ...
The role of the South Indian and Pacific oceans in South American monsoon variability
(SPRINGER WIEN, 2008)
This work has investigated the impact of three different low-frequency sea surface temperature (SST) variability modes located in the Indian and the Pacific Oceans on the interannual variability of the South American Monsoon ...
Surface ocean response to synoptic-scale variability in wind stress and heat fluxes off south-central Chile
(Elsevier, 2014)
The effect of the high frequency (synoptic) variability of wind and
heat fluxes upon the surface ocean off south-central Chile (west
coast of South America) is investigated using a regional ocean
model. We focus our ...
Climate precursors of multidecadal drought variability in the western United States
(2004-12-07)
Low-frequency (periodicities lower than 20 years) hydrologic variability in the western United States over the past 500 years is studied using available tree-ring reconstructions of Palmer Drought Severity Index (PDSI), ...
