non-ENSO modes
ResumoThe dominant seasonal surface air temperature (SAT) anomalous modes over entire South America (SA) for the 19512010 period were investigated. The El Niño-Southern Oscillation (ENSO) and non-ENSO (residual RES) characteristics of the SAT anomalous modes and the associated precipitation and temperature advection anomalies were discussed. The SAT (referred to as TOT) and RES modes were obtained from the empirical orthogonal function analyses, and the ENSO modes from the correlation analyses between the SAT anomalies and the Oceanic Niño index. The SAT TOT modes are in general, weakly linked to the ENSO, except for the first summer and the fourth spring TOT modes. For these two modes, the precipitation variations are more crucial than the temperature advection variations in defining the SAT anomaly patterns. On the other hand, the first winter and autumn TOT modes contain mostly the non-ENSO components and feature an extensive warmed area in tropical and subtropical SA. For these modes, the subtropical warming is due to the temperature advection. The TOT modes with a weak relation to the ENSO and the corresponding RES modes show a dipolar pattern with a warm node in tropical SA and the cold one in extratropical SA, and is determined mostly by the precipitation. Nevertheless, the cold advection reinforces the cold node of the winter and summer modes. In some cases, the regional systems contribute to the SAT anomalies. The South American low-level jet contributes to the positive SAT anomalies in central and eastern Brazil for the second winter and first spring RES modes and the South Atlantic Convergence Zone influences the first summer RES mode. The SAT modes describe mostly the interannual variations of the SAT patterns over SA, but some of them also contain decadal and multidecadal time scale variations.

ResumoAnomalous seasonal patterns of precipitation variability over South America (SA) associated with El Niño-Southern Oscillation (ENSO) and non-ENSO (residual) conditions were assessed during 19512016. Patterns were obtained from empirical orthogonal functions analysis of total and residual precipitation seasonal anomalies. In austral spring and summer, precipitation variability is dominated by a dipolar anomaly mode with a centre extending from northwestern to northeastern SA and another in central-eastern Brazil and part of southeastern SA (SESA) during spring, and a centre in northwestern SA and another extending from northeastern SA to central and eastern Brazil and central SESA, during summer. These modes are associated with ENSO to a greater extent during spring than summer. In summer, there is a strong association of the dipolar precipitation pattern with sea surface temperature (SST) anomalies on the east coast of Brazil, which indicates local influence. In austral fall, SST anomalies in the tropical South Atlantic relate to precipitation anomalies in northeast SA, and those in the tropical north Atlantic (TNA) to precipitation anomalies in northwestern SA, through the intertropical convergence zone anomalous position modulated by SST anomalies. In this same condition, the ENSO acts only to intensify or weaken the dominant precipitation pattern, depending on its phase, mainly over SESA. In contrast, the second variability mode in fall is characterized by positive SST anomalies in the Indian Ocean and equatorial and southern Atlantic Ocean and negative in the TNA. The importance of ENSO and the Indian Ocean in the characterization of the SST dipole in the tropical Atlantic explains the main changes in precipitation patterns over northeastern Brazil not been discussed in previous studies.

El Niño-Southern Oscillation
ResumoThis paper analyses the relations between the El Niño/Southern Oscillation (ENSO) mode in the tropical Pacific and the sea surface temperature (SST) modes in the South Atlantic for the 1900 2006 period. In the South Atlantic, two modes are analysed in more detail: the South Atlantic dipole (SAD) mode, with centres at (15°S, Greenwich longitude) and at (37.5°S, 25°W) and the southwestern South Atlantic (SWSA) mode, with centres at (30°S, 40°W) and at the southern midlatitudes. The ENSO and SAD modes are lagged or lead connected depending on the period of analysis. An El Niño (a La Niña) precedes by up to 6 months the establishment of a positive (negative) SAD mode during the 1920 1930 and 1940 1980 periods. Otherwise, a positive (negative) SAD mode precedes by up to 1 year the establishment of a La Niña (El Niño) during the 1975 2000 period. On the other hand, the SWSA is strongly driven by the ENSO. The effects of both the SAD and SWSA modes on the South American rainfall are also discussed on a seasonal basis. In general, the SAD (ENSO) mode has a weak influence on the ENSO-related (SAD-related) rainfall anomalies over South America. On the other hand, in general, the SWSA and ENSO modes have a combined effect on rainfall of the southern and southeastern regions of South America. A particularly important result of the present analysis for climate monitoring and forecasting purposes seems to be the changing relations between the SAD and ENSO modes.

ResumoThis study addresses seasonal predictability of South American rainfall during ENSO. The skill of empirical and coupled multi-model predictions is assessed and compared. The empiricalmodel uses the previous season August- September-October Pacific and Atlantic sea surface temperatures as predictors for December-January-February rainfall. Coupled multi-model 1-month lead December-January- February rainfall predictions were obtained from the Development of a European Multi-model Ensemble systemfor seasonal to inTERannual prediction (DEMETER) project. Integrated (i.e. combined and calibrated) forecasts that incorporate information provided by both the empirical and the coupled multi-model are produced using a Bayesian procedure. This procedure is referred to as forecast assimilation. The skill of the integrated forecasts is compared to the skill of empirical and coupled multi-model predictions. This comparison reveals that when seasonally forecasting December- January-February South American rainfall at 1-month leadtime the current generation of coupled models have a level of deterministic skill comparable to those obtained using simplified empirical approaches. However, Bayesian combined/ calibrated forecasts provide better estimates of forecast uncertainty than the coupled multi-model. This indicates that forecast assimilation improves the quality of probabilistic predictions. The tropics and the area of South Brazil, Paraguay, Uruguay and Northern Argentina are found to be the two most predictable regions of South America. ENSO years are more predictable than neutral years, the latter having nearly null skill.

ResumoThis study examines the Interdecadal Pacific Oscillation (IPO) modulation of the El Nino-Southern Oscillation (ENSO) teleconnections in its decaying stages with the tropical ocean by focusing on the Indian Ocean Basin-Wide (IOBW) mode and the precipitation over South America (SA) in the 1901-2012 period. Composite analyses revealed that the ENSO teleconnections are IPO-modulated due to the differential ENSO decaying speed, which is slower during the positive than negative IPO phase, for both El Nino (EN) and La Nina (LN) cases. Negative precipitation anomalies related to EN persist over northeastern SA until austral winter for the positive IPO phase (POS IPO), while significant opposite sign anomalies occur in this region for the negative IPO phase (NEG IPO). These results are associated with the Walker circulation's reversal during NEG IPO which is, in turn, accompanied by negative IOBW. During the POS IPO, the positive IOBW causes upward movements over there and, by continuity, downward movements over SA. In the NEG IPO, for LN events the wave train originating in the north of Australia propagates toward subtropical SA, which, coupled with the surface circulation, causes dryness in this region. In addition, the rapid decay of LN in the NEG IPO, followed by the emergence of EN, caused changes in the Walker circulation, such that enhanced upward movements occurred over the Pacific and SA region, and downward movements over the Indian Ocean until austral winter. In turn, the slower decay of the LN in the POS IPO maintains strong subsidence over the central Pacific and weak upward motions over western SA. So, the EN (LN) and positive (negative) IOBW during the POS (NEG) IPO prolong the scarcity of precipitation over equatorial (subtropical) SA. Persistent dry periods over these regions during the ENSO decaying stage might have important implications for the seasonal forecasts.

Palavras-ChaveCoastal Atacama desert
El Niño-Southern oscillation
Holocene debris flows
ResumoIn its modern sense, El Niño-Southern Oscillation (ENSO) encompasses tropical-extratropical climate teleconnections that result into positive rainfall anomalies in subtropical western South America. The hyper-arid coastal region of southern Peru and northern Chile, located at the core of the Atacama Desert, exhibits a transitional climate between this subtropical regime and the near-equatorial region where direct ENSO effects are experienced. Meteorological mechanisms associated to the occurrence of heavy rainfall episodes along the coastal areas of southern Peru and northern Chile have been assessed to investigate their relationship with modern tropical-extratropical climate teleconnections. In this context the onset and evolution of Holocene El Niño manifestations are inferred from the analysis of new and previous geologic information in this hyper-arid coastal desert. Our results indicate that heavy rainfall and debris flow events in the southern Peru coastal region occur mostly, but not exclusively, associated to the build-up of potential instability due to positive sea-surface temperature anomalies, and its episodic release by lifting the marine boundary layer in connection with deep mid-latitude troughs and associated jet-streaks from equatorially-deflected Pacific South America (PSA) teleconnection patterns during the mature (austral summer) and the development phase (austral winter-spring) of El Niño events, respectively. Along the coast of northern Chile, those events occur almost exclusively in austral winter-spring. The comparison of debris flow and flood deposits from both areas support the onset of modern El Niño manifestations at 5,300-5,500 Cal. BP, as well as increased frequency of major events during the last thousand of years and particularly during the 20th century, consistently with other proxies of ENSO variability from the western slope of the Andes and from the equatorial Pacific Ocean. Different manifestations during the late Pleistocene and early to mid Holocene in both regions suggest that this climate teleconnection pattern did not operate at that time. We suggest that an increased frequency of debris flows between 12,900 and 8,400 Cal. BP exclusively in southern Peru, previously interpreted as an indication of strong El Niño events at that time, is most probably associated to short but intense heavy rainfall episodes, similar to those that develop at present times during the late winter-spring season in non-El Niño conditions, in which low-level wind convergence at the bend of the South American west coast (18°S) provides an extra lifting mechanism that amplifies side effects of mid-latitude disturbances. These condition would be enhanced in austral spring during the cold phase of the ENSO cycle (la Niña) and longer-period ENSO-like oscillations, when strong southerly winds and an enhanced subtropical anticyclone prevail over that area..
