Title: Beaufort scale of wind force as adapted for use on forested areas of the northern Rocky Mountains

Author: Jemison, George M.;

Date: 1934

Source: Journal of Agricultural Research. 49(1): 77-82.

Publication Series: Scientific Journal (JRNL)

Description: The Beaufort scale of wind force, internationally employed by weather agencies, was not designed for use on mountainous and forested areas like those of the Rocky Mountains of northern Idaho and western Montana. The United States Forest Service has used it to estimate wind velocities in this region, but has found that in too many cases the resulting estimates were inaccurate: In the northern Rocky Mountain region the scheme of forest fire protection demands reliable estimates of wind velocity. Wind exerts an important influence upon the rate at which forest fuels dry and upon the rate at which fire spreads, and the region contains relatively few stations where wind velocity is actually measured. Where measurements are not available, reliable estimates of wind velocity are indispensable in determining potential fire danger, are useful in connection with placing men and camps on going fires, and have an appreciable bearing on the rating of efficiency of control action.
