The rates of atmospheric pollution are increasing in world over the years, which makes this topic more and more concerning. Weather conditions, associated with anthropogenic factors, play a fundamental role in modifying the air quality. In this context, this article aims to analyze the influence of meteorological factors during critical episodes of air pollution in the city of Itabira – Minas Gerais. Hourly air quality and meteorological data, provided by the Municipal Environment Secretariat (SMMA) of the Itabira City Hall, were used in this analysis. A selection of the critical events was made and, after that, the composites and daily anomalies for each event were calculated. The results obtained showed that in the critical days of pollution negative anomalies of precipitation, atmospheric pressure, relative humidity and wind speed were observed. For temperature, solar radiation and wind direction the anomalies are positive during critical days. In terms of emitting sources, there has been an increase in the vehicle fleet since 2014, presenting a positive trend of 1.151 vehicles per year. In addition, a number of 111 fire outbreaks were observed on the most critical day of all events. It is important to highlight the role of air quality control and monitoring, together with the analysis of meteorological conditions, as, currently, the maximum values established by legislation do not include changes in weather conditions, that can worsen air quality and harm the health of the population.
