Eddy kinetic energy
South Atlantic
ResumoThe spatio-temporal variability of the eddy kinetic energy (EKE) in the South Atlantic Ocean (SAO) is investigated using 19 years of satellite altimetry observations. The EKE in this region presents different significant frequency modes. The interannual to intrannual cycles dominate the EKE variability spectrum. Spatial patterns of the EKE variance were also determined and associated with the propagation of the Agulhas Current eddies across the SAO. At the annual frequency, EKE anomalies are generated in the Agulhas leakage (AL) region and propagate westward. The interannual signal was associated with the Antarctic oscillation and displays a stationary spatial oscillation pattern in the Agulhas eddy corridor (AEC). This is the first time that a full spectral analysis of the EKE variability in the SAO is produced. Results show that the AEC is an important feature in the SAO, with low (high) frequencies associated to the west (east) part of the basin. The AL is a significant source of mesoscale variability to the South Atlantic subtropical gyre.

South Atlantic Convergence Zone (SACZ)
ResumoThe objective of this work is to use the Laboratoire de Météorologie Dynamique (LMD - France) Atmosphere General Circulation Model to investigate the relationship between SST anomalies in Pacific and Atlantic Oceans (in the confluence region of Brazil and Falklands currents) and the climate variability over South America and South Atlantic. Particularly this work has intended to study how the climate in these regions behaves when the position of Brazil and Falklands currents was modified, along with El Niño, La Niña and neutrality situations in the tropical Pacific. Initially it was made a simulation using climatological SSTs (control simulation). Next, idealized scenarios (forced) have been created for simulating the presence of El Niño/La Niña and/or positive/negative SST anomalies in the confluence region of Brazil and Falklands currents (in the other regions SST remains climatological). In fact, in the confluence region, it was used positive SST anomalies to simulate the Brazil current more to the South and negative ones in case of the Falklands currents more to the North. All the simulations (control and forced) have had the same initial conditions. This way, nine simulations have been generated. All of them had been run from October to February using ensemble forecasting technique with ten members each. Results had been generated for December/January/February summer trimester. Initial data correspond to the first ten days of October 1997 proceeding from NCEP (National Centers for Environmental Prediction) reanalysis at 00 UTC. Sea surface temperature (SST) data are from optimum interpolation (OI) analysis. This data correspond the monthly means between 1971 and 2000 and they had been interpolated to daily values to force the model. Both initial and boundary data had been interpolated to the model grid. Results show that the greatest effect of SST anomalies in the confluence region occur in the SACZ region. Positive SST anomalies tend to diminish precipitation in the SACZ region, while negative SST anomalies cause an increase in this region. These alterations are linked to changes in pressure patterns in this region. In relation to the joint effect of El Niño and positive/negative SST anomalies in the Atlantic, increase of precipitation in the SACZ region was evidenced in both cases. Similar results had been found for La Niña and positive/negative SST anomalies in the Atlantic.

ResumoSea surface temperature (SST) anomalies influence atmospheric circulation and contribute to changes in weather and climate around the globe. It is already known that precipitation over continental areas can be associated with SST variability in the tropics. However, the importance of extratropical oceans is still not completely understood. The aim of this study is to investigate the influence of extratropical SST anomalies to rainfall variability, focusing on South America, and the oceanic and atmospheric processes involved. The period from 1981 to 2010 was studied in a monthly scale, using SST and precipitation data obtained from NOAA datasets (ERSST-v5 and GPCP, respectively), and atmospheric data from CFSR reanalysis. Singular Value Decomposition (SVD) showed connectivity between SST variations in extratropical oceans and rainfall variability over southeastern South America, an important agricultural area. Extreme wet and dry events over this region were identified using the Standardized Precipitation Index (SPI), to a further evaluation of the oceanic conditions associated with these episodes. Empirical Orthogonal Functions (EOF) and SVD were applied for the identification of principal modes of variability. Dipoles of SST were identified in South Pacific and South Atlantic oceans. Two areas of opposite signs were observed in western (~25°S) and southern (~55°S) South Pacific Ocean, regions of atmospheric blocking and the South Pacific Convergence Zone (SPCZ). Positive SST anomalies in the southern area are related to precipitation increase over southeastern South America. The southern oceanic area is also associated with a dipole of precipitation over Southeast Asia and central Pacific Ocean. A dipole signal was also noticed in western South Atlantic Ocean, mainly from September to December, varying in position and intensity near South America. The results obtained showed that extratropical oceans have an important role for precipitation variability in remote regions, and the oceanic areas identified can contribute to climate monitoring.

ResumoRelationships between deep convection over South America and the atmospheric circulation are examined, with emphasis on submonthly variations of the South Atlantic convergence zone (SACZ) during austral summer. Outgoing longwave radiation (OLR) is used as a proxy for convection, while the associated circulation patterns are depicted by the National Centers for Environmental Prediction Reanalysis. Over South America and the adjacent oceans, OLR fluctuations with periods less than 90 days show maximum variance in the SACZ and over central South America during December–February. There is a local minimum in variance over the southern Amazon Basin, where mean convection is at a maximum. OLR spectra display several statistically relevant peaks corresponding to periods of less than 30 days over tropical South America, with the relative proportion of higher-frequency power increasing as the base grid point is moved to the southeast within the SACZ. Correlations between submonthly (2–30-day) OLR in the vicinity of the SACZ and 200-mb streamfunction reveal the preferred path of Rossby wave energy impinging on the SACZ from the midlatitudes of the Southern Hemisphere. Episodes of enhanced convection within the SACZ, indicated by negative OLR anomalies, occur at the leading edge of upper-level troughs propagating into the region. The corresponding pattern at 850 mb reveals that the disturbances are nearly equivalent barotropic west of South America but tilt westward with height in the region of the SACZ. Negative low-level temperature anomalies lie to the southwest of the convection. The results are consistent with baroclinic development along an associated cold front. Convection over the southwestern Amazon Basin on submonthly timescales is seen to progress into the region from the south. Upper-level anomalies, which at times may play a role in the initiation of the convection, move eastward and rapidly become decoupled from the convection. Low-level cold air along the eastern flank of the Andes appears linked to the convection as it moves northward. In contrast, convection over the southeastern Amazon is accompanied by disturbances moving into the area from the Atlantic, but there is little sign of a low-level temperature anomaly. In this case convection seems to result in cross-equatorial outflow into the North Atlantic, rather than be the result of forcing from the extratropics. The authors speculate that the relatively stable position of the SACZ is associated with a Rossby wave guide, which ultimately is related to the large-scale circulation driven by sources and sinks of diabatic heating. It also appears that the SACZ forms when the northwesterly flow associated with a low-level trough is able to tap moisture from the Amazon.

ResumoSouth Atlantic Ocean variability is investigated by means of an ocean general circulation model (ORCA2), forced with the NCEP/ NCAR-reanalysis for the 1948-1999 period.A rotated EOF analysis of the mixed layer temperature suggests a breakdown of the South Atlantic into three subdomains, with characteristic spatial and temporal scales: (a) the tropical Atlantic, with mainly interannual fluctuations, (b) the subtropics, with variability on an interannual to decadal scale, and (c) the midlatitudes, with interannual and multidecadal variability. These modes are closely connected to anomalous atmospheric circulation patterns, which induce typical forcing mechanisms for each region. Temperature changes in the western to central tropics are found to be driven by changes in surface heat fluxes and horizontal advection of heat, while in the central to eastern tropics and the northern Benguela, temperature changes are connected to reduced vertical entrainment, altering the depth of the mixed layer and leading to reduced upwelling. In the subtropics, changes in the net surface fluxes drive the upper ocean temperature anomalies, and wind induced vertical mixing dissipates them, inducing changes in the depth of the mixed layer. Anomalous heat and volume transports are found to be related to anomalous Ekman and geostrophic currents. A wind driven mechanism is suggested, whereby changes in Ekman related heat and volume transport lead to modulations of the subtropical gyre and thus to changes in the geostrophic related heat and volume transport. The midlatitudes experience temperature changes mainly due to horizontal advection and wind induced vertical mixing, whereby geostrophic advection of heat dominates in the western to central area, and Ekman induced heat transports are confined to the eastern midlatitudes. Results from a SVD analysis between mixed layer temperatures and sea level pressure suggests that these forcing mechanisms, their associated regions and time scales, as well as heat and volume transports are also valid for the coupled ocean-atmosphere system. end{abstract}.

El Nino-Southern Oscillation
ResumoIn this study, we examined intrusions of the high potential vorticity (HIGH-PV) at the 350 K isentropic level over the South Atlantic during the period December-January-February (DJF) 1979-2001. These events have a large interannual variability and are negatively correlated with the Southern Oscillation Index. Many events occur during the El Nino years except in 1997/1998, while there are none or few cases in La Nina years except in 1988/1989. The intrusion events which show interactions between the tropics and extratropics are associated with the 'westerly ducts' in the tropics and also with the amplitude of quasi-stationary waves and subtropical jet intensity.

ResumoThe intraseasonal variability of the South Atlantic Convergence Zone is investigated applying statistical techniques to the daily NCEP/NCAR reanalysis data set and the daily-interpolated NOAA satellites OLR, both ranging from 1979 to 1999. The data were filtered to retain frequency fluctuations between 30 and 90 days. The intrinsic connection among tropical convection in the Indonesian region, the subtropical flow and the convection in the South Atlantic Convergence Zone (SACZ) is discussed. The analyses are consistent with previous suggestions of the influence of Madden-Julian Oscillation (MJO) on tropical South American convection and studies of the Pacific South American (PSA) wavetrain role on SACZ. In the present study, the two dominant intraseasonal modes of variability affecting the SACZ are discussed on the basis of a zonal mode (the Madden-Julian Oscillation) and a tropical-extratropical mode (Pacific South American Pattern). The opposite convective behaviour between Indonesia and tropical South America is discussed, as well as the connection between SACZ convection and PSA-like pattern. It was noticed that an SACZ episode occurring in the northernmost position can be influenced by the MJO, and can trigger a wavetrain over the South Atlantic and Indian Ocean, while positions further south can be influenced by a tropical-extratropical PSA-like wavetrain. High-frequency (2-10 days) analysis displayed dominant wavetrain patterns of shorter wavelength than the intraseasonal wavetrain, but with similar characteristics, over South America, indicating the influence of synoptic systems, like frontal zones, over the continent. It is suggested that when these two frequencies, high (frontal systems) and intraseasonal (MJO or PSA), are in phase, they are able to establish appropriate conditions for an SACZ episode development.

ResumoThe availability of observational ocean wave data in the South Atlantic Ocean (SAO) is still very limited. Due to this shortage of data obtained in situ, numerical modeling has become the most used tool for the investigation of wave climate in whole world. Here, the global model WAM was used to simulate waves from June 2006 to July 2007 in order to better understand the wave variability in short-scale. For this was applied the EOF and SVD analysis which have found the leading modes of the significant wave height (Hs), swell, velocity of the wind at height 10 meters (U10) and peak period (Tp) in the SAO. The large share of wave variability was explained by the first four modes, where a strong correlation was found between Tp and swell (68%) and also that with Hs (61%). The cross-correlation functions of the 1st and 2nd PCs time series were calculated and compared to Southern Annular Mode (SAM). The results have led us to conclude that the leading potential mechanism that drives the short-scale variability of ocean surface wave in the SAO is the extratropical cyclone amount variability. It could be noticed that the first modes of U10 and Hs were significantly related, as well as their second modes. The spatial pattern of the EOF3 of U10 started appearing in the EOF3 of Hs, but became really similar to the fourth mode of the Hs, what outpoint the known time lag of ocean surface response to the atmospheric forcing. The EOF1 of swell has exhibited positive anomalies in southeast of grid and lowering of them toward northeast, showing that there is a correspondence between the propagation directions of swell and the dominant directions of storms. From spatial patterns were noticed contributions of swell from Pacific, Indian and North Atlantic Oceans. The anomalies (+) observed in the first and second Hs modes showed a contribution of swell from the Indic Ocean modifying the wave climate in the SAO. The application of cross-correlation function of PCs time series has provided the information that one maximum oscillation happened in each two day. We guess that this short and synoptic scale can have some relation to the extratropical cyclone variability. A clear seasonal fluctuation could be noted, particularly for the summer months, but the period studied is much short for a deep seasonal analyze. The negative tendency of SAM added with its also negative correlation coefficient with all variables analyzed indicate that the storms have shifted toward midlatitudes, and, consequently, larger is the chance to occur swell events. In this way, the results obtained here lead us to conclude that the leading potential mechanism that drives the short-scale variability of Hs and swell in the SAO is the extratropical cyclone amount variability. The application of EOF and SVD methods for obtaining leading modes of short-scale spatial temporal variability of oceanic waves, apart from appearing pioneer in the South Hemisphere, provided a better understanding of the ocean waves behavior in the South Atlantic Ocean and the relationship to local process, to other Oceans and to the high latitudes process.

ResumoOcean colour radiometry (OCR) provides essential information for studies of primary productivity, heat fluxes, and biogeochemical cycles in the upper ocean. Generalized OCR models relating satellite radiometric data to biogeochemical variables are developed using global in situ data sets. However, when applied to specific regions these models commonly give results with significant deviation from in situ measurements, mainly due to field and satellite measurement uncertainties and model underrepresentation of ocean colour variability. Hence to improve OCR products further understanding of the sources of measurement uncertainty and bio-optical variability across different oceanic regions is needed. This work was focused on the Southern Atlantic and Southeast Pacific Oceans encompassing important biogeochemical provinces with highly distinct optical waters. In situ data was collected during a summer campaign on board the research vessel Melville (MV1102 cruise). The first part of the investigation was an uncertainty analysis of the radiometric and bio-optical data with three main objectives: (i) test different radiometric techniques with above and in-water approaches (ii) apply closure analyses with forward modeling of remote sensing reflectance (Rrs); and (iii) analyze the impacts of the uncertainties on operational OCR models. The uncertainty analysis revealed moderate to high levels associated with the various techniques, with 12 to 26\% relative differences (RD) for the ocean-colour bands (412- 555 nm) and 3-12\% for the reflectance ratios (412-510/555). The use of a merged Rrs (Instruments, INS) reduced uncertainties since each individual technique was subject to different instrumental and environmental biases. Complete closure was not obtained, especially for the stations with more adverse environmental conditions (with winds, waves and clouds), with 18-34\% RD compared to modeled Rrs bands. Nonetheless, the impact of INS uncertainties on retrieved OCR products for empirical and semi-analytical (SA) models was still generally smaller than the intrinsic errors of the inversion schemes. Hence, the approaches applied to obtain more accurate measurements were effective in reducing the main sources of uncertainties. Significant sources of deviations of the OCR models were related to the optical variability of the study region and intrinsic model errors. The second part of the investigation analyzed the sources of bio-optical variability and their relations to biogeochemical variables across distinct provinces. The bulk inherent optical properties (IOPs) were in first order associated with the chlorophyll a concentration (Chla) gradient. Second order variations were explained by specific IOPs linked to the phytoplankton community structure, composition and size distribution of the particle assemblage and variability of the coloured dissolved and particulate organic matter (CDM). To synthetize the first and second order optical variations across the study region, a Regional Specific Optical Water Type (R-SOWT) classification was proposed by defining 5 classes that integrate the specific IOPs and bio-optical indices, i.e., a phytoplankton Size Index, CDM index, the specific backscattering coefficient (bbp/Chla) and spectral slope ($\eta$). The R-SOWT significantly improved the performance of SA models by using class-specific parameterizations, especially for the bbp retrieved by the GSM (Garver-Siegel-Maritorena) model, reducing from 35 to 9\% RP, and the CDM absorption coefficient of the QAA (Quasi-Analytical Algorithm) model, reducing from 30 to 23\% RD. For more optically complex waters the improvements of the retrievals were much more significant. Further analysis of spatiotemporal variations of the optical relations and applicability of the R-SOWT for different seasons (and regions) are recommended for future studies. This approach has potential to improve OCR satellite products and be used as a new product that integrates relevant information for biogeochemical studies. RESUMO: A radiometria da cor do oceano oferece informações essenciais para estudos de produtividade primária, fluxos de calor e ciclos biogeoquímicos na superfície dos oceanos. Modelos generalizados de cor do oceano que relacionam dados radiométricos de satélite com variáveis biogeoquímicos são desenvolvidos com bases de dados globais in situ. No entanto, quando aplicados a regiões específicas estes modelos apresentam desvios significativos que estão relacionados a incertezas nas medidas in situ e satelitais, e sub-representações da variabilidade da cor do oceano. Portanto, para a melhoria de produtos de cor do oceano é preciso conhecer melhor as fontes incertezas das medidas e a variabilidade bio-óptica em diferentes regiões oceânicas. O presente trabalho teve como foco os Oceanos Atlântico Sul Sub-tropical e Pacífico Sudeste abrangendo importantes províncias biogeográficas com águas opticamente distintas. Dados in situ foram coletados durante uma campanha de verão a bordo do navio de pesquisa R/V Melville (MV1102). A primeira parte do trabalho compreendeu análises de incertezas dos dados radiométricos e bio-ópticos com três objetivos principais: a) a comparação de diferentes técnicas de amostragem com instrumentos emersos e submersos; b) comparações com a reflectância de sensoriamento remoto (Rsr) modelada; e c) análises dos impactos das incertezas em modelos operacionais de cor do oceano. As análises de incertezas revelaram níveis de altos a moderados associados às diferentes técnicas, com diferenças relativas (DR) de 12 a 26\% para as bandas de cor do oceano (412-555 nm) e 3 a 12% para as razões de bandas (412-510/555). O uso de uma medida de Rsr integrada (Instrumentos, INS) reduziu as incertezas já que cada técnica individual estava sujeita a diferentes erros instrumentais e ambientais. O ajuste perfeito com a Rsr modelada não foi obtido, principalmente para as estações com condições ambientais mais adversidades (de vento, ondas e nuvens), com 18-34\% DR para as bandas espectrais. Ainda assim, o impacto das incertezas do INS foi de modo geral, menor que os erros intrínsecos aos modelos empíricos e semi-analíticos (SA) de cor do oceano. Dessa forma, os métodos empregados para obter medidas mais acuradas foram razoavelmente eficazes em reduzir as incertezas. Desvios significativos dos modelos de cor do oceano foram relacionados à variabilidade óptica da região de estudo e erros intrínsecos aos modelos. A segunda parte da investigação compreendeu análises das fontes de variabilidade bio-óptica e suas relações com as variáveis biogeoquímicas nas diferentes províncias. A distribuição dominante das propriedades ópticas inerentes (POIs) esteve associada ao gradiente de concentração de clorofila a (Cla). Variações de segunda ordem foram relacionadas a POIs específicas associadas à estrutura da comunidade fitoplanctônica, a composição e distribuição do tamanho das partículas e à variabilidade da matéria orgânica dissolvida e particulada (MODP). Para sintetizar as variações de primeira e segunda ordem na região de estudo, uma classificação Regional de Tipos Específicas de Águas Ópticas (R-TEAO) foi proposta para definir 5 classes, integrando as POIs específicas e índices bio-ópticos, i.e., o Índice de tamanho do fitoplâncton, índice de CDM, o coeficiente especifico de retroespalhamento das partículas (bbp/Cla) e o parâmetro de variação espectral ($\eta$). O R-TEAO melhorou significativamente o desempenho de modelos SA com parametrizações especificas para cada classe, reduzindo a DR do bbp do modelo GSM01 (Garver-Siegel-Maritorena) de 35 a 9\% e o coeficiente de absorção do MODP de 30 a 23\% para o modelo QAAv5 (Quase Analytical Algorithm). Para águas mais opticamente complexas a melhoria dos modelos foi ainda mais significativa. Análises das variações espaço-temporais das relações ópticas e a aplicabilidade do R-TEAO para estações sazonais diferentes e outras regiões oceânicas, são recomendadas para pesquisas futuras. O método tem potencial de ser aplicado para a melhoria de produtos de cor do oceano por satélite e ser usado como um novo produto integrando informações importantes para estudos biogeoquímica.
