Perfil topo climático do Cerro do Botucaraí, em Candelária/RS, de abril e maio de 2016

Este trabalho tem como objetivo analisar a variabilidade termo-higrometrica na localidade do Cerro do Botucarai, em Candelaria, Rio Grande do Sul, considerado o ponto isolado mais alto do estado com 569 metros de altitude acima do nivel do mar. A analise foi feita com os valores medios diarios e mensais de temperatura e umidade relativa do ar relativos ao meses de abril e maio de 2016, coletados em dois pontos distintos, sendo um deles da base do Cerro do Botucarai e o outro do topo do Cerro de mesmo nome. Com esta analise foi possivel observar que as temperaturas no topo do Cerro do Botucarai, sao em geral, mais baixas do que em sua base e ha tres casos de ocorrencia de inversao termica entre os dois pontos, sendo dois deles no mes de abril e um no mes de maio. Durante a analise foi identificada a variacao de altitude entre estes dois pontos como sendo o principal fator causador da variabiliadade da temperatura do ar e, consquentemente, da umidade relativa do ar.

SPATIAL VARIABILITY OF AIR TEMPERATURE WITH MOBILE TRANSECTS IN ERECHIM/RS, IN POLAR DOMAIN TROPICALIZATION PROCESS

This research concerns in to analyze the spatial distribution of air temperature in the urban area of ​​Erechim/RS, under polar domain tropicalization process. In carrying out this climate research in loco needed to conduct field work with implementing the mobile transects methodology. Was measured air temperature 15 PM. It was made spatial variation map of air temperature recorded in the urban environment and used the synoptic maps, satellite imagery and data of the official network of weather INMET stations for identification of active weather systems and comparisons with the data and its magnitude. After climate and cartographic analysis, it was observed that the thermal variations on this primary research, occurred significantly, registering differences of up to 46,4°F between the districts of the city, and amortization that green areas can play in this environment, reducing up to 50% of the highest temperatures recorded in Erechim. Still, for this city, slope aspect and the presence of water bodies, were very important to the spatial differentiation of temperature compared to the industrial areas, low-income peripheral and central/commercial.

DISTRIBUTION OF PRECIPITATION IN THE VERANIL PERIOD AND WINTRY 2013/2014 IN THE URBAN AREA OF SANTA MARIA/RS AND ITS SURROUNDINGS

This paper concerns in to analyze the rainfall distribution in the seasonal period of summer of 2013/2014 and in the winter of 2014 on the urban area of Santa Maria/RS and its surroundings. For the development of this paper 10 rain gauges were built and installed in strategic points, elaborated according to Milanesi; Galvani (2013), plus the official weather sta tion of the University Federal of Santa Maria/INMET. In the analysis of the results it can be observed that in the summer period the higher total pluviometric were localized at North and Northeast of the urban area. at South and Southwest of the urban area has the smaller total pluviometric of the seasonal period of summer. In the winter period it can be observed that the higher total pluviometric were localized at North of the urban area, next to P07 in Fundacao Moa and in the neighborhoods of Chacara das Flores. Already the smaller total pluviometric are located at South and Southeast of the field of study. Thereby the pluviometric spatial-temporal distribution in the urban area of Santa Maria and its surroundings are influenced by two factors: one is the displacement of the polar fronts, and the other is the relief, although it is not significant, most cases.
