Synopsis

Excerpt from Using Fire-Weather Forecasts and Local Weather Observations in Predicting Burning Index for Individual Fire-Danger Stations

Any agency engaged in forest-fire control needs accurate weather forecasts and systematic procedures for making the best use of predicted and reported weather information. This study explores the practicability of using several tabular and graphical aids for con verting area forecasts and local observations of relative humidity and wind Speed into predicted values for individual fire-danger stations. Diffities in preparation and use of these aids by field personnel were investigated during 2 summers on 5 ranger districts in the na tional forests of Oregon and Washington. Emphasis was given to ac curacy of predictions of changes and other situations important to fire control. Actually tested were: (1) aids for adapting area forecasts of wind speed and relative humidity, (2) a procedure for predicting wind speed, (3) aids for the use of predicted relative humidity in forecast ing fuel moisture, and (4) routine statistical procedures for predicting wind Speed, fuel moisture, relative humidity, and burning index class.

Performance of the various methods varied considerably be tween stations, depending on the complexity of the relation between station weather and the prevailing weather situation. Aids utilizing area forecasts could not, of course, correct basic forecast errors. Aids based on climatic averages would be incorrect with any depar ture from a normal weather situation. Diffity of aid preparation was another serious handicap. Nevertheless, certain aids showed real promise for some stations, thus permitting more intensive use of forecasts and other weather information now available. In the course of the study, improvements were made in methods previously suggested for predicting the burning index.
