Previous issue date: 2014-12-15 / Este trabalho realizou um estudo a partir de um conjunto de dados meteorol?gicos coletados na cidade de Natal/RN e adjac?ncias, identificando evid?ncias de altera??es no seu clima urbano no per?odo de 1970 a 2010. As vari?veis utilizadas foram: temperatura m?dia, temperatura m?nima e umidade relativa. Os dados foram obtidos a partir das esta??es meteorol?gicas localizada no Campus Central da Universidade Federal do Rio Grande do Norte (UFRN), que faz parte da rede de observa??es do Instituto Nacional de Meteorologia (INMET), e do Centro de Lan?amento da Barreira do Inferno (CLBI), localizadas dentro de uma ?rea urbana e de uma ?rea de prote??o permanente (APP), respectivamente. Foi realizada uma an?lise sobre a varia??o sazonal das vari?veis meteorol?gicas.Al?m disso, foram avaliadas as tend?nciasnas s?ries temporais,utilizando para isso o template MAKESENS, que aplica o teste de Mann-Kendall e o m?todo de estimativa de inclina??es de Sen sobre o conjunto de dados. Para a temperatura m?dia, na UFRN/INMET, houve tend?ncia de crescimento nos meses de maio, julho e setembro, nos n?veis de signific?ncia de 10%, 5% e 10%, respectivamente. No CLBI, s? houve tend?ncia de crescimento da temperatura m?dia no m?s de fevereiro, no n?vel de signific?ncia de 10%. Em rela??o ? temperatura m?nima, houve tend?ncia de crescimento com signific?ncia estat?stica em quatro s?ries (janeiro, novembro, dezembro e m?dia anual) na UFRN/INMET, nos n?veis de 10%, 10%, 5% e 5%, respectivamente, e apenas em uma no CLBI, no m?s de setembro, no n?vel de signific?ncia de 10%. Em rela??o ? umidade relativa, os resultados foram extremamente discrepantes. Para a UFRN/INMET, houve tend?ncia de decrescimento com signific?ncia estat?stica em 7 das 13 s?ries, sendo elas janeiro, mar?o, abril, maio, outubro, novembro e m?dia anual, nos n?veis de 5%, 1%, 0,1%, 10%, 5%, 5% e 0,1%, respectivamente, enquanto que no CLBI houve uma tend?ncia predominante de crescimento, com signific?ncia de 1% em junho e de 5% em agosto.Essas tend?ncias s?o mais evidentes na ?rea urbana em rela??o ?ssuas adjac?ncias, evidenciando algumas caracter?sticas t?picas das Ilhas de Calor Urbanas. / This work conducted a study from a set of meteorological data collected in the city of Natal / RN and surroundings, identifying evidence of changes in its urban climate during the period from 1970 to 2010. The variables used were: average temperature, minimum temperature and relative humidity. Data were obtained from the meteorological stations located in the Central Campus of the Federal University of Rio Grande do Norte (UFRN) that is part of the network of observations from the National Institute of Meteorology (INMET) and from Barreira do Inferno Launch Center (CLBI), located inside an urban area and inside a permanent protection area (APP), respectively. An analysis of the seasonal variation of the meteorological variables was performed. In addition, the trends were evaluated in time series, using for this the template MAKESENS, that applies the Mann-Kendall test and Sen's slopes estimates with the data set. For the average temperature in UFRN/INMET, there was growth trend in May, July and September, at the significance levels of 10%, 5% and 10%, respectively. In CLBI, there was only upward trend in average temperature in February, at the 10% significance level. Regarding the minimum temperature, there was growth trend with statistical significance in four series (January, November, December and annual average) in UFRN/INMET, at the levels of 10%, 10%, 5% and 5%, respectively, and just one in CLBI, in September, at the 10% significance level. In relation to the relative humidity, the results were extremely disparate. To UFRN/INMET, there was decreasing trend with statistically significance in 7 of the 13 series, these being January, March, April, May, October, November and annual average, at the levels of 5%, 1%, 0.1%, 10%, 5%, 5% and 0.1%, respectively, while in CLBI there was a prevailing trend of growth, with a significance of 1% in June and 5% in August.These trends are more pronounced in urban areas compared to surrounding area, showing some typical characteristics of Urban Heat Islands.
