Aspectos da variabilidade da temperatura do ar em Belo Horizonte, a partir de série de dados da estação meteorológica do Centro de Desenvolvimento da Tecnologia Nuclear

Abstract

In order to contribute to the production and analysis of climatic data for the construction of dispersion models of radionuclides and pollutants in general, this article analyzes the variations in air temperature obtained from the Meteorological Station of the Nuclear Technology Development Center (EMET / CDTN) in Belo Horizonte-MG. To arrive at the results, the data were selected and analyzed by means of the percentage variation of the air temperature over the years in relation to the average. The results of the maximum, average and minimum temperature calculations from 1997 to 2017 were evaluated in parallel with data from the meteorological station of the official network of INMET (1961-2018) Belo Horizonte, to identify patterns in the variability of this atmospheric attribute. To perform the statistical analyzes, the MINITAB17 program and the Excel software were used to compile the data and build the graphs, the results of which indicated, in addition to the percentage variation of the thermal amplitude per year in relation to the average, three climatic categories (cold, hot and habitual).
