Abstract

The results of a statistical analysis of the daily values of Angstrom Fire Index (AFI) for Nalchik (Kabardino-Balkaria, Russian Federation) in comparison with values of AFI 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 Nalchik is observed on average within 53 days a year (in Telavi - within 67 days a year), and increased - within 39 days a year (in Telavi - within 43 days a year). Between the daily and monthly mean values of AFI in Telavi and Nalchik direct correlation is observed.
