Coastal ocean observing and modeling systems (coastal observatories), connected with regional global systems, improve the quality of information forecasts for effective management safe sustainable maritime activities. The public availability systematic long-term is an engine Blue Economy, boosting economic growth, employment, innovation. An overview some Brazilian initiatives presented in this paper, involving universities, private companies, federal state agencies, covering institutions...
The Atlantic Meridional Overturning Circulation (AMOC) is a crucial component of our climate system, influencing water mass formation and transformation. It driven by buoyancy fluctuations mixing within the column. AMOC often studied using models calculating strength indexes based on constant depth intervals (z-AMOC). However, at high latitudes, where deep forms in Atlantic, isopycnals are much steeper than subtropical regions. This means that z-AMOC framework may not fully capture processes...
ABSTRACT. The results of two high-resolution ocean global circulation models – OGCMs (Hybrid Coordinate Ocean Model HYCOM and Circulation andClimate Advanced Modeling Project OCCAM) are analyzed with a focus on the Western Boundary Current (WBC) system South Atlantic Ocean. volumetransports calculated for different isopycnal ranges, which represent most important water masses present in this region. latitude bifurcation zonalflows reaching coast, leads to formation southward or northward WBC...
An oceanic forecast system was created for the southeastern Brazilian region. A 9.5 years spin up, from January 2000 to July 2009, used adjust model Regional Ocean Modelling System (ROMS) forced by climatologies and National Centers Environmental Prediction (NCEP) surface fluxes. After this period, became operational with atmospheric fluxes Global Forecast (GFS). The produces daily analysis five days forecasts in a fully automatic manner. In addition routine task of running model,...
During the austral winter of 2008, thousands penguins traveled to low latitudes along South Atlantic coast America. The atmospheric and oceanic conditions from April July 2008 may account for penguins' unusual geographic distribution. that period, coastal waters were cooler; wind anomalies had northward onshore components; ocean's region presented currents favored travel toward lower latitudes. This anomalous climate regime resulted extreme meteorological frontal systems occurred mainly...
. The oceanic features in the eastern and southeastern Brazilian shelf/slope between 13◦-31◦S are investigated using ROMS (Regional Ocean Model System). model was integrated for 9 years it forced with: i) 6-hourly synoptic atmospheric data from NCEP; ii) initial boundary conditions OCCAM (Ocean Climate Circulation Advanced Modelling) monthly mean climatology iii) tidal forcing TPXO 7.1 global set. results were compared with observations, which consisted thermodynamic MDL (Mixed Layer Depth)...

The Brazilian Equatorial Shelf (BES) is one of the few macrotidal regions worldwide. This study used a high-resolution numerical configuration ocean model ROMS forced with realistic surface and lateral forcing, as well tides river discharges. Tidal heights more than 2 m were found in three BES due to large tidal amplification across estuarine channels inside each region: Amazon, Para´, Maranha˜o, for considerable time fraction. Heights between 4 5 occurred frequency greater 20-30% some...
No verão austral de 1994 a 2019, as anomalias do nível mar em Santos/SP filtradas na frequência corte 28 horas apresentaram tendência linear +0,00002 m/ano, média 0,02382 m e variabilidade interanual. Os valores acima da +2 desvios-padrão ocorreram entre 11 22 fevereiro/2018 concomitantemente alagamentos registrados nessa Cidade pela Defesa Civil local. Esse período, definido como o Dia 0, foi selecionado para investigação influência vento superfície nesses valores. Quatro dias antes houve...
