Interdecadal variability of the austral summer precipitation over the Central Andes
(Frontiers Media, 2022-09-12)
The impacts of the interdecadal variability of the Pacific and the Atlantic Oceans on precipitation over the Central Andes during the austral summer (December January-February, DJF) are investigated for the 1921–2010 period ...
Frequency of extreme rainfall events in Southern Brazil modulated by interannual and interdecadal variability
(WILEY-BLACKWELL, 2009)
The frequency of extreme rainfall events in Southern Brazil is impacted by Ell Nino - Southern Oscillation (ENSO) episodes, especially in austral spring. There are two areas in which this impact is more significant: one ...
Spatial distribution and interannual variability of coastal fog and low clouds cover in the hyperarid Atacama Desert and implications for past and present Tillandsia landbeckii ecosystems
(SPRINGER WIEN, 2021)
The hyperarid Atacama Desert coast receives scarce moisture inputs mainly from the Pacific Ocean in the form of marine advective fog. The collected moisture supports highly specialized ecosystems, where the bromeliad ...
Climate change along the arid coast of northern Chile
(Royal Meteorological Society, 2011-06-12)
Long-term precipitation records from the extremely arid northern coast of Chile (18 °S–30 °S) were analysed
to assess changes occurring at different time scales. Results are presented here along with a discussion on changes ...
Principal modes and related frequencies of sea surface temperature variability in the Pacific coast of North America
(Journal of Oceanography, 2003)
We examined monthly time-series (1950 to 1999) of sea surface temperature (SST) anomalies in 47 quadrants (2° 2°) along the Pacific coast of North America. Correlation, clustering and principal components analyses were ...
Evaluating SODA for Indo-Pacific Ocean decadal climate variability studies
(Journal of Geophysical Research: Oceans, 2014-10-31)
Estimates of changes in upper ocean temperature, heat content, and sea level are dependent on the coverage of subsurface observations in space and time. Historically, these data are sparse, which has limited our understanding ...
Changes in the zonal propagation of El Niño-related SST
(Springer Wien, 2016-03)
Long-term variability of El Niño (EN) cycle has been the topic of several studies, mainly because of its impacts on climate around the globe. This variability has been mainly described by changes in the intensity and ...
Estudio de la variabilidad climática en un transecto andino-tropical en el austro ecuatoriano mediante la identificación de teleconexiones
(Universidad de Cuenca, 2020-06-19)
The climate in south Ecuadorian is characterized by the complex climatic variability
in the region, causing local hydroclimatic events that cannot be adequately prediction.
Certain global signals synthetize exactly the ...
Oceanic influence on southernmost South American precipitation
(Universidad Nacional Autónoma de México. Centro Ciencias de la Atmósfera, 2012)
The potential oceanic influence on southernmost South American precipitation since 1930 is analyzed in this study. The aim is to define oceanic characteristics that can produce wetter or drier conditions over the mentioned ...
Enhancement of coastal upwelling and interdecadal ENSO-like variability in the Peru-Chile Current since late 19th century
(2007)
Secular trends in coastal upwelling proxies from a sediment record at 23 degrees S encompassing 250 years reveal two distinct stages separated by a transition period between AD 1820 and 1878. Persistent interdecadal ...
