Abstract

Çanakkale that is located in the subtropical Mediterranean climate is characterized with semi-humid climate conditions in general, and summer dryness. Drought conditions and drying prevailing northerly sector winds (e.g. Poyraz) in summer are favorable for occurrence and dispersing of the forest fires during the summer months.

(4) Keetch-Byram drought index (KBDI) reached the highest value on the day of 10.08.2008 with an index value of 530. (5) KBDI applied to the 2008 data of the Çanakkale meteorological station did not reach the definite fire level within that year.
