The daily values of these indices for the period 2005-2015 were related to the forest fire database. It was found that there is a relatively weak to moderate correlation between forest fires and the values of the Canadian Forest Fire Weather Index. In order to improve the wildfire risk assessments (including forest fires), the index was modified. The modified index has a significantly greater correlation with the actual events of forest fires and consequently a much wider application in southern Serbia. The modified index can be of great importance in the future concepts of forest fire risk management. https://unilib.phaidrabg.rs/o:4378 doi:10.2298/TSCI190412276R RATKNIĆ, Tatjana RATKNIĆ, Mihailo RAKONJAC, Nikola ŽIVANOVIĆ, Ivana PODUŠKA, Zoran 2019 info:eu-repo/semantics/article http://creativecommons.org/licenses/by/4.0/legalcode forest fire, assessment, risk, modified index, Serbia THERMAL SCIENCE 23(6)
