The share of electricity generation from Variable Renewable Energy Sources (VRES) has increased over the last 20 years. Despite promoting decarbonization energy mix, these sources bring negative characteristics to such as power ramps, load mismatch, unpredictability, and fluctuation. One ways mitigate is hybridization plants. This paper evaluates benefits hybridizing a plant using an AI-based methodology for optimizing wind–solar ratio based on Brazilian regulatory system. For this study,...
Abstract To evaluate the energy flux from mean flow of South Atlantic western boundary currents toward typical Cabo Frio eddies (at Brazilian southeast coast), southwestern circulation was simulated with Princeton Ocean Model. Throughout study period, vertical profile eddy available potential direction monitored. The results indicated that baroclinic instability first appear in intermediate depths and then its signal propagates upward, draining Brazil Current (BC), until it reaches surface,...
Neste estudo é realizada uma investigação, via modelagem computacional, das influências remotas que as anomalias positivas da temperatura superfície do mar (TSM) na região Confluência correntes Brasil e Malvinas (CBM), exercem no regime hidrometeológico regiões Sul Sudeste Brasil. Essa marcada por intensa frente oceânica formada pelo encontro águas transportadas pela Corrente (CB) (CM). investigação foi com a utilização modelo climático Community Atmosphere Model 2.01 (CAM 2.01), sendo...
To reduce uncertainty regarding the contribution of continental shelf areas in low latitude regions to air-sea CO2 exchange, more data are required understand carbon turnover these and cover gaps coverage. For first time, inorganic alkalinity were measured along a cross-shelf transect off coast Maranhão (North Brazil) 9 cruises spawning from April 2013 September 2014. On last 4 transects, dissolved organic matter nutrients also measured. The highest concentrations observed close land. As...
The EOSOLAR project was designed to investigate the structure of atmospheric boundary layer in an equatorial coastal zone, where discontinuity surface conditions induces non-stationarity gradients wind speeds and development internal layers. proposed methodology considers several aspects sea–land transition meteorology that are essential for precisely estimating wind–solar energy potential assessment structural loads on turbines. Infrared (LIDAR) acoustic (SODAR) ground-based remote sensing...
The objective of this work is to assess the wind resources east coast Maranhão, Brazil. Wind profilers were combined with micrometeorological towers and atmospheric reanalysis investigate micro- mesoscale aspects variability. Field campaigns recorded winds in dry wet seasons, under influence Intertropical Convergence Zone. season was characterized by strong (8 12 m s−1) from northeast. Surface heat fluxes generally positive (250 320 W m−2) at midday negative (−10 −20 during night. Convective...
This study aims at improving the understanding of behaviour vegetation in Brazil due to regional influences climatic events, specifically El Niño-Southern Oscillation (ENSO). To accomplish this we used a set filtered data from European Fourier-Adjusted and Interpolated Normalized Difference Vegetation Index (EFAI-NDVI), generated by Advanced Very High Resolution Radiometer (AVHRR), along with Condition (VCI), spatial resolution 0.1° × temporal 10 days, covering period 1995 1999. Through...
ABSTRACT: The fish assemblage structure in a port area São Marcos Bay (Amazonic coast) was evaluated based on the spatial and temporal distributions to identify potential changes response anthropic pressure increases associated with industrial activities region. samples were taken between March 2011 November 2015. ichthyofauna represented by total of 56 species, distributed 15 orders 29 families. Captures dominated Genyatremus luteus (Bloch, 1790), but Sciades proops (Valenciennes, 1840)...
This article seeks to compare the performance of a LIDAR Windcube V2, manufactured by Leosphere, with that SODAR MFAS, Scintec, in evaluating wind speed at different altitudes. The data from these two sensors were collected three locations on Brazilian equatorial margin state Maranhão. comparison aims their simultaneous use points. horizontal velocity components, altitude, showed Pearson correlation values above 0.9 and for vertical component between 0.7 0.85. As sampling efficiency, had...
Monitoring the volume and heat transports around world oceans is of fundamental importance in study climate system, its variability, possible changes. The application an Oceanic General Circulation Model for climatic studies needs that dynamic thermodynamic fields are equilibrium. time spent by model to reach this equilibrium called spin-up time. This work presents some results obtained from Modular Ocean version 4.0 initialized with temperature, salinity, velocity sea surface height data...
Meteorological events cause pronounced low-frequency sea level variations along the Mid-Atlantic coast of South America. Spectral analysis hourlysea data during 1983 from tide gauges at Puerto Madryn and Mar del Plata, Argentina, Cananeia Ilha Fiscal, Brazil, yielded energetic variance peaks withperiods between 2 28 days, with good coherence among four gauges. These results suggest that coherent disturbances may propagatealong America towards northeast, mostly as barotropic shelf waves. The...
