Statistical Characteristics of Angstrom Fire Index for Telavi (Georgia)

Abstract

The results of a statistical analysis of the daily values of the Angstrom Fire Index (I) for Telavi (Georgia) in the period 2010, 2012-2015 are presented. AFI = (R/20) + (27-T)/10, where R is the minimum relative humidity, T is the maximum air temperature. The gradations of the values of I are as follows: I. AFI> 4.0 - Fire occurrence unlikely, II.AFI = 4.0 ÷ 2.5 - Fire conditions unfavorable, III. AFI = 2.5 ÷ 2.0 - Fire conditions favorable, IY. AFI = <2.0 - Fire occurrence very likely. In particular, it was found that a high fire hazard in Telavi is observed on average within 67 days a year, and increased - within 43 days a year. The largest number of days with high fire hazard was observed in 2013 (98 days), the smallest - in 2012 (44 days). Further, it is planned to expand work on this issue (using other more complex fire hazard indices, studying their trends in connection with climate change, determining these indices for other points in Georgia, etc.).
