title: Nexus: Water, Climate, Energy and the Environment - A Perspective on the Itataia-CE Development

description: Abstract The water viability of the Uranium and Phosphate Exploration and Processing Complex in Santa Quitéria - Ceará was analyzed from the relation of the water, energy and climate nexus. In order to do so, rainfall, evapotranspiration and flow projections were carried out using the global models of the Coupled Model Intercomparison Project Phase 5 (CMIP5, used in the fifth Intergovernmental Panel on Climate Change - IPCC-AR5). Data from Ceará's energy matrix were also considered in order to verify the state's increased energy demand and to analyze the impact of its production on water resources. The models differ in the future of precipitation, but most indicate an increase in evapotranspiration over the three projected periods (2015-2044, 2045-2074 and 2075-2099) in the two scenarios chosen (RCP4.5 and RCP8.5) indicating a possible increase in water demand for the region.

title: Performance of the Cordex Project Simulations with Regard to the Representation of the Patterns of Variation of the Precipitation in the XX Century on the Municipality of Fortaleza, Ceará

description: Abstract The evaluation method applied was the one proposed by Silveira et al. (2019). The research sought to evaluate simulations of the Cordex Project models for the South America domain that provide monthly frequency rainfall data from the Historical experiment family for the city of Fortaleza, Ceará. Four RCMs were found nested with ten GCMs totaling sixteen combinations named here simply by “models”. To perform the comparison, data from the Pici Station (338001) obtained from the HidroWeb Portal during the period from 1970 to 2005 were used. The regional ETA model presented the best performance in the representativeness of the present climate. Driving by the global CanESM2 model, according to the AVALs index, was the best simulation for the period evaluated with a CORREL of 0.96 and RMSE_PC of 3.01%. The direct relationship between the classification order and grid spacing was evident, that is, the higher the resolution of the model, the better positioned in the classification. After evaluating these models, researchers interested in applying modeling data in Fortaleza will have a scientific framework to adopt appropriate models in their research. In theory, models that can adequately represent the present climate, possibly also will be able to represent the future climate.

title: Analysis of Daily Rainfall and Spatiotemporal Trends of Extreme Rainfall at Paraná Slope of the Itararé Watershed, Brazil

description: Abstract The knowledge of intensity and frequency of rainfall allows establishing predictive measures to minimize impacts caused by high volume of rainfall totals in a region. Therefore, the objective is to evaluate daily rainfall for Paraná slope of the Itararé watershed (PSIW) and to verify the spatiotemporal trend of intense and extreme daily rainfall. Rainfall data from 14 stations collected from 1976 to 2012 were used with less than 4% of data faults. Multivariate analysis based on cluster analysis technique (CA) was used applying the Euclidean distance for the identification of homogeneous groups, and the quantiles technique to classify daily rainfall. The Mann-Kendall (MK) test was used to identify trends for annual rainfall totals, annual number of rainy days (ANRD) and for the occurrence of intense (R95p) and extreme (R99p) rainfall. The CA technique identified three rainfall groups (HG I, II and III). Given the latitudinal position of the area, rainfall at the southern sector is characterized by its greater similarities with the subtropical climate, whereas in the North sector there is a consistent reduction of rainfall totals in autumn and, especially, during winter months, which are characteristic of the tropical climate. The MK test identified the downward trend of ANRD, with greater significance for the south-centered sectors of the basin. The observed trends for the intense (R95p) and extreme (R99p) daily rainfall show the predominance of reduction for the Southwest and central sector, followed by a significant increase in the Southeast and North sectors of the PSIW.

title: The Scarabs and the Meteorological Conditions

description: Abstract Study the meteorological factors is important to understand scarabs population dynamics. So this study examined the relationship between meteorological conditions and the scarabeids population fluctuation in Mata de Cocal in Teresina-PI from August 2011 to July 2012. Scarabs were collected weekly in 12 pitfall traps unattractive. It confirmed canonical correlation between the monthly occurrence record in the Scarabaeidae species in the group of monthly data of insolation, pluviometric precipitation, relative humidity and temperature, with a magnitude of 1, chi-square equal to 390.15 with 40 degrees of freedom and p-value corresponding equal to &lt; 0.0001. Significantly (p &lt; 0.0001), there was canonical correlation between insolation data (0.31), pluviometric precipitation (0.26), humidity (0.03) and temperature (-0.16) in the monthly occurrence record of the scarabeids. In this way the population fluctuation of certain scarabs species, mainly, Coprophanaeus jasius (0.47; p &lt; 0.0001), Deltochilum sp. (0.32; p &lt; 0.0001) and Dichotomius nisus (0.48; p &lt; 0.0001) is governed predominantly by regional variables and their presence is conditioned by meteorological parameters, insolation principally.

title: Mitigation of the Effects of Climate Change from the Gradual Replacement of Coal Thermal Power Stations by Photovoltaic Plants

description: Abstract This paper focuses on reducing the emission of greenhouse gases and the volume of water captured in the energy generation process in thermoelectric plants thar use mineral coal and intensify the water crisis in regions of the Brazilian semiarid. The study was made in the largest coal-fired power plant in Brazil, Energia Pecém, located in Porto do Pecém, in the state of Ceará, taking unit Pecém II. Is is proposed to shut down this unit for seven hours a day from the operation of a large photovoltaic plant installed in áreas classified as desert in the state, specifically in the municipality of Irauçuba, with the same generation as that thermoelectric plant. For this, a preliminar project of a photovoltaic plant was made, whose technical, economic and environmental feasibility was assessed. Thus, it is estimated a drop in carbono dioxide emission of around 34,720.56 tons per month and in water abstraction a reduction of 9.67% of its monthly volume.

title: Forecast of Sea Surface Temperature (SST) in Tropical Atlantic with the use Artificial Neural Networks

description: Abstract Many studies show that the sea surface temperature in the tropical Pacific and Atlantic oceans is the main influencer physical variable climatic conditions in various areas of the globe. Thus, the observations and forecasts of ocean variables such as sea surface temperature, constitute a valuable tool for climate monitoring and better use of natural resources, particularly in regions that are vulnerable to the impacts of climate change, as is the case of Northeast Brazil. The present work aims to implement and evaluate a method that object to use Artificial Neural Networks to predict the sea surface temperature in the Atlantic Ocean Tropical and the meridional gradient of sea surface temperature anomalies in the Tropical Atlantic. The results showed that the correlations, Significant to 95% according to the Student t-test, were better for the FMA and MAM quarters, where the coefficients showed values greater than 0,75 for some regions of the ATN. To estimate the Meridional Gradient, the RNA showed similar performance to persistent. The best results occur when using the average of the TSM from the DJF quarter. For this configuration the correlation coefficient was 0,74.

title: Ciclones em Superfície nas Latitudes Austrais. Parte III: Energética

description: Abstract This study presents the energy analysis of four cyclone cases in southern latitudes, being two extratropical (one Bjerknes and Solberg type and the other Shapiro and Keyser type), a tropical and a subtropical, in order to complement the work “Surface Cyclones over Austral Latitudes: Part II Cases Study”. We applied the eddy kinetic energy equation developed by Orlanski and Katzfey, because it contemplates the main mechanisms for the formation and dissipation of the transient systems, namely baroclinic and barotropic instabilities and downstream development. The energy analysis shows that the baroclinic conversion term was the most important during the life cycle of the four studied cyclones, whereas the barotropic term was small. On the other hand, the downstream development term, known also as ageostrophic flow convergence, had negative contribution for all cases, exporting kinetic energy out of the cyclone region.

title: Parâmetros Biofísicos Aplicados no Parque Nacional da Serra das Confusões, Piauí-Brasil

description: Abstract The objective of this work is to evaluate the biophysical parameters, rainfall and surface temperature in the vegetation conditions, in the Serra das Confusões National Park (SCNP), Piau-NEB. With the aid of the images obtained from the satellite Landsat 8 it was possible to calculate the Normalizes Difference Vegetation Index (NDVI) and the surface temperature (Ts). The SCNP rainfall presented a well-defined seasonality, dry and rainy seasons, which play a crucial role in the vegetation conditions of the SCNP. The NDVI class (&gt; 0.693) had the greatest reduction o the coverage area around 72.7%, while the classes (0.347-0.433) and (0.433-0.52) had an increase of 34.7% and 31, 8%, respectively. In addition, it was clear that vegetation condition influenced the Ts of the region.
