Summary/Abstract: The emissions produced in forest fi res are transported through the air to different areas of the emission source causing an increase in the concentrations of different pollutants in cities. On June 20, 2020 in Verjoyansk (Russia, Eastern Siberia) the temperature reached a maximum of 38ºC (100.4°F) as a result of a heat wave caused by increased forest fires. In the same way, Bolivia had forest fires causing various direct and indirect effects in the last years. Forest fires which occurred between 2000 and 2019 in the eastern region of Bolivia could influence the maximum temperatures recorded in Oruro and as a consequence of this relationship heat waves were formed. The hypothesis tested was: “The higher the number of fire sources in the eastern region of Bolivia, the higher the maximum temperature values in Oruro”. Maximum temperature series (TM) and heat sources (FC) stored in INPE-Brazil were evaluated with descriptive statistics parameters, assumptions of the linear regression models, and Spearman’s correlation. Heat waves were detected with 90th percentile and four consecutive days of TM. In 20 years the TM series goes from 11.8 to 26.6ºC and the FC series goes from 9 to 34.574. Both series do not respond to the assumptions of the linear model, so the Spearman correlation was applied. Based on the proposed research hypothesis it is concluded that there is a correlation between the monthly maximum temperatures and the monthly heat sources in the months of April and May with a level of significance of = 0.05. In this case the daily series of TM show the formation of heat waves.
