The results showed a similar behavior in relation to the seasonal cycle of the monthly average concentrations of O3 and CO, with the lowest values of CO and O3 occurring in the first half of the year and a gradual increase from June, with peaks in September and October. Due to highest occurrence of fires in the region during its dry season. In relation to the variability associated with ENSO, an increase in O3 and CO concentrations was observed in the year 2015, classified as year of El Niño, in relation to the year 2008 and 2011, classified as La Niña year. The observations made by the environmental satellite AQUA provide a set of useful data for conducting studies on the relationship between climatic conditions and atmospheric pollution levels in the region.Item Analise da frequência e intensidade da precipitação nos aeroportos de Ponta Pelada E Eduardo Gomes na cidade de Manaus - AM(Universidade do Estado do Amazonas, 2017-12-01) Rocha, Charlis Barroso da; Souza, Rita Valéria Andreoli de; Souza, Jaidete Monteiro de; Souza, Rodrigo Augusto Ferreira deThis study aimed to evaluate the frequency and intensity of precipitation for two regions of the city of Manaus - AM in the period 2009-2016. For this, precipitation data of two stations, the Eduardo Gomes Airport (AEG) and Ponta Pelada Airport (APP) locates in the south and northwest of the city of Manaus were used. The methodology consisted of evaluating seasonal and diurnal variability of rainfall in terms of intensity and frequency. Initially, the monthly rainfall accumulation of the two regions was calculated for each year separately, in order to compare with the climate of Manaus. Then, monthly and daytime frequency of precipitation and the seasonal distribution of the insensitive of the rain events were calculated. In general, the total monthly precipitation for the AEG and APP followed the seasonal precipitation of the city of Manaus. However, in some years, values below or above monthly climatology are observed, possibly associated to interannual variability of the El Niño-Southern Oscillation phenomenon. Concerning the classification by rain intensity, in the two regions the highest frequencies occur in the very low precipitation category (0.2 - 1.6 mm) during the January, February and March (JFM) trimester. Events considered extreme (> 18 mm) also occur more frequently in the JFM period, but with smaller numbers of occurrences. The frequency of monthly rainfall showed a higher occurrence of events in the rainy season of the Amazon Region (December to April), with higher values in April, while that in period from June to November (dry season) shows the lowest occurrences, with lower values in September. In relation to the daytime frequency, the highest frequency occurs from 10-15 local time and secondary peaks occur by dawn (00 local time), morning (06 local time) and night (18 local time) on most months.Item Análise da relação entre as ocorrências de inundações e precipitação na cidade de Manaus para o ano de 2014(Universidade do Estado do Amazonas, 2018-06-15) Miranda, Priscila Pereira de; Dehaini, Jamile; Souza, Rita Valéria Andreoli de; Souza, Rodrigo Augusto Ferreira deThis work presents a study on the relationship between rainfall and number of floods in the city of Manaus-AM. In order to explore this relationship, flood records of the Civil Defense of Manaus were used for the period from 2010 to 2014. The rainfall variability over the city was analyzed through rainfall records of rain gauges distributed in five of the six zones that comprise the urban zone of Manaus for the year 2014. Pearson's correlation was used to validate the results. In general, it can be said that the stations SBMN, MAUÁ, BETA and EST followed the seasonal precipitation of the city of Manaus. On the other hand, the ALFA and SBEG stations presented different behavior. ALFA with low rainfall rates from April to October, and also in December. SBEG presented monthly accumulations superior to the climatology from March to December, mainly emphasizing the behavior of the rains during the dry period (jul-ago-set). This distinct behavior among the zones must have been caused by differences in land use, proximity to forested areas and influence of river breeze. With respect to flood cases, when monthly totals are analyzed for each year, greater records are observed during the rainy season and during the months of occurrence of Rio Negro maximum levels. The year of 2014 presented high values in the months of March (associated with accumulated precipitation in all zones), May and June, where the last two coincides with the months of occurrences of Rio Negro maximum levels. In relation to other years, the year 2011 presented the highest number of cases for the rainiest months (February and April) that may be associated with the increase of precipitation over the region due to a strong La Niña event occurring in the years 2010-2011 . The neighborhoods that stood out as the most susceptible to flood events were those of Jorge Teixeira (ZL), Terra Nova (ZN), Educandos (ZS), Tarumã (ZO), Alvorada (ZCO) and Flores (ZCS). The zones where the stations of MAUÁ, BETA and EST are located showed a strong correlation between precipitation and floods, when considering the monthly totals. Nevertheless, through the test of significance, only the BETA (ZN) station showed a correlation with a relatively strong degree. On the other hand, the results related to the daily correlation did not present significant values, presenting great dispersion in all the areas considered.Item Avaliação do conforto térmico para quatro diferentes locais de Manaus AM(Universidade do Estado do Amazonas, 2019-12-06) Capobiango, Katharina De Carvalho; Souza, Jaidete Monteiro de; Oliveira, Maria Betânia Leal de; Dehaini, Jamile; Santos, Rosa Maria Nascimento dos; Oliveira, Maria Betânia Leal deThe continuous growth of Manaus has direct impact on landscape, with the replacement of green areas for materials that have a higher heat capacity, such as concrete, asphalt, roofing, among others. As a result, there are changes in the urban microclimate, and consequently on the thermal comfort of the population, which can still be aggravated during the occurrence of climate systems such as El Niño that reduces precipitation significantly in the region. In this study, we evaluated both the meteorological variables and human comfort index (HCI) obtained in four (4) different locations, three (3) in the urban area of Manaus, and one (1) in the rural area surrounding the city. The seasonality of the HCI was related with the distribution of precipitation throughout the year, with a variation of 4.0, 4.4 and 5.0 °C between October and December, in the stations EST, IFAM and CMM, in that order. HCI differences between sites indicate direct relation with the characteristics of the analyzed surface coverage. Although the relative humidity is larger in rural area, this is more comfortable because of the lower temperatures. For the stations of the urban area, located in the central region of the city, it was the least thermally comfortable, surpassing the air temperature by up to 13.8° C. Despite the similar features in EST and IFAM, higher temperatures in IFAM are found because this stations is installed on top of the roof, resulting in approximately 1.0° C higher HCI. In addition to the influence of surface coverage on ICH between sites, the occurrence of the very strong El Niño 2015/16 has enhanced the thermal discomfort in the South zone of Manaus, with difference compared to 2018 of up to 4.0° C.Item Relação entre o modo meridional de TSM no Pacífico e o ENOS e seus efeitos sobre a precipitação na Amazônia(Universidade do Estado do Amazonas, 2019-12-06) Moraes, Djanir Sales de; Souza, Rita Valéria Andreoli de; Dehaini, Jamile; Oliveira, Maria Betânia Leal deIn this study we aim to caracterize the Pacific Meridional Mode (PMM) of Sea Surface Temperature (SST) and its relationship with El Niño-Southern Oscillation (ENSO) and the rainfall in the Amazonic region during 1901 to 2010. The methodology of this study is based on the method of Combined and Extended Empirical Orthogonal Function (CEOF and EEOF respectively) to identify the spatial and temporal patterns of the PMM. Composite analyses and linear correlation tools are used to search for the relations between the PMM, ENSO and precipitation. The results show that the spatial pattern of PMM presents a variability of 8 years and is best defined in the months of June through August (JJA). Correlations between the timeseries associated with PMM and precipitation show a temporal dependency, with a change of pattern after the 1980s. The effects combined of ENSO and PMM on the precipitation over Tropical South America were also investigated. In this case, the results suggest that the ocurrence of positive or negative PMM patterns during the initial phase of ENSO events can act in the sense of configurating the positioning of the maximum anomaly centers associated with ENSO and as as consequence alter the pattern of precipitation over the Amazon. On the other hand, ENSO in its decaying phase doesn’t seem to interfere in the development of PMM and its relation with rainfall.Item Padrões Decenais do Gradiente Inter-Pacífico-Atlântico e a Precipitação da América do Sul(Universidade do Estado do Amazonas, 2018-12-03) Rego, Willy Hagi Teles; Souza, Rita Valéria Andreoli de; capistrano, Vinicius Buscioli; Dehaini, JamileThe Pacific and Atlantic Tropical oceans are responsible for most of the climate variability in the tropical region. Even though independent, they can form together an interannual variabil ity mechanism called the Inter-Pacific-Atlantic gradient, which is also modulated in decadal scales by the positive and negative phases of the Atlantic Multidecadal Oscillation (+AMO and -AMO). The present work investigated the variations in the associated atmospheric and oceanic patterns during austral winter through both AMO phases and its impacts on South America’s (SA) Precipitation anomalies (APRP). Results show that this phenomenon is a dominant vari ability mode during austral winter, characterized by Sea Level Pressure anomalies (SLPA) and Sea Surface Temperature anomalies (ASST) gradient between both tropical oceans. Selection of extreme events shows an equal distribution of positive events (+PC1) for both phases while the negatives (-PC1) are more frequent during -AMO. +PC1 events during +AMO are charac terized by an west-east ASST gradient made by the anomalous cooling (warming) of Tropical Pacific (Atlantic), especially at Central Pacific (Tropical North Atlantic, responsible for posi tive (negative) APRP at SA’s Extreme-North (Central-West and South) region. +PC1 events in -OMA are equatorially confined and show similar impacts in SA’s rainfall. The ATSM gradi ent becomes east-west for -PC1 events due to Tropical Pacific (Atlantic) anomalous warming (cooling), even though they are equatorially confined only during +AMO periods. These events are related to positive (negative) APRP for the Center-West and South-Southeast (North) SA regions during both phases. Results show that different oceanic and atmospheric patterns com pose the Inter-Pacific-Atlantic sector’s variability, which impacts SA’s rainfall significantly and can be felt though the entire continent.Item Relação das variáveis hidrometeorológicas com os casos de malária nos Municípios da Bacia do Rio Negro-AM(Universidade do Estado do Amazonas, 2019-12-06) Figueiredo, Ranyelli Cunha de; Dehaini, Jamile; Souza, Rita Valéria Andreoli de; Souza, Rodrigo Augusto Ferreira de; Capistrano, Vinicius BuscioliMalaria is a high-risk infectious disease that causes great concern and high costs to public health, especially in tropical and subtropical regions of the world. The Amazon region has a high endemic rate of malaria, in which its hydrometeorological characteristics are preponderant for longevity, vector density of the transmitter and the reproduction of the pathological agent of the disease. It becomes important, diagnose how the hydrometeorological conditions of each region are associated with the occurrences of malaria and understand how the variability of these conditions are associated, with the incidence of the disease. The objective of this work is to analyze the influence of the conditions hydrometeorological conditions and their variability in the incidence of malaria cases in the municipalities of Manaus, Barcelos and São Gabriel da Cachoeira, which are bathed by the Negro River, in the State of Amazonas. The results show that during the driest period in the region, the malaria cases are more prevalent, this relationship is observed by Pearson's correlation coefficient, where precipitation, relative air humidity and the height of the Rio Negro showed a moderate and negative correlation with the incidence of malaria, and temperature showed a positive and moderate correlation with the incidence of malaria. The analysis for the ENSO event shows that the variability caused in the hydrometeorological elements, can potentiate/attenuate the incidence of malaria.Item Construção de campos de temperatura da superfície de rios para inserção em modelos de mesoescala(Universidade do Estado do Amazonas, 2019-12-05) Batista, Lourdes Gabriela Vieira; Veiga, José Augusto Paixão; dehaini, Jamile; Souza, Jaidete Monteiro deThe present work aims to propose three methods for the construction of spatial fields of surface temperature of rivers (SRT), from remote and interdisciplinary information. situ, for insertion into mesoscale models. Remote information comes from of the AQUA and TERRA satellites that have irregular temporal frequency (01:30, 10:30 ,13:30 and 22:30 local time). In situ data, on the other hand, come from a station meteorological station, installed on the banks of the Rio Negro, with regular temporal frequency. To construct the TSR fields with a regular time frequency of 1/1h (method 1 and 2), remote and local information was combined using a weighting factor calculated as a function of the observed RRT diurnal cycle. The observed data allowed the increase in satellite data frequency and the construction of TSR fields in high temporal resolution (1/1h). One of the methods developed for creating fields of TSR, uses only information from satellites (method 3), targeting places where it is not there is in situ surface temperature information. Despite the limitations, the methods applied in the construction of the TSR fields were able to represent the characteristics of rivers and temperature behavior within the diurnal cycle. Although it presents limitations related to the temporal variation of temperature, method 2 was the method that produced TSR fields with behavior closer to the observations, both in in relation to the curve of the diurnal cycle in terms of temperature values.
