PREFACE 



In October 1976, as part of a technical-scientific exchange program 

 in forestry, a team of forest fire specialists from the United States 

 visited the Soviet Union. Frank Albini, representing Forest Fire and 

 Atmospheric Sciences Research, worked at the Leningrad Forestry Re- 

 search Institute. The Institute is the main organization performing fire 

 research for protecting forests in the Soviet Union. 



Dr. Albini collaborated with Candidate Georghy N. Korovin, chief 

 of the computational methods laboratory, and members of his staff, in- 

 cluding Ms. E. H. Gorovaya, on the analysis presented in this paper. 

 The group formulated the scope of the analysis, methods of computation, 

 and mathematical expressions. Numerical results were generated inde- 

 pendently and compared later. This paper, in Russian, is included in 

 the annals of the Leningrad Institute for 1977. The translation presented 

 here should be useful in tactical planning for forest fire suppression, a 

 matter of practical importance in both countries.
