Understand how spot fires are predicted with practical calculator math.
This book presents the equations used to estimate spotting distance in fire behavior, including how wind, terrain, and multiple burning trees affect the spread of embers. It focuses on a field procedure and shows how to apply the model to real-world scenarios.
The text explains how the equations are built, how they are used in a calculator program, and how to operate the procedure in practice. It also includes notes on the assumptions behind the model and how real conditions may cause distances to differ from the prediction. The materials cover both a torching-tree scenario and a pile-burning scenario, with guidance on choosing inputs and interpreting results.Learn the key factors that influence spot-fire distance, including flame height, wind, and terrain.See how the calculator program and data cards are organized to work with different tree species.Follow the operating procedure step by step to run the model and read flat-terrain and mountainous-terrain results.Understand the context and limitations of the model as part of field forecasting. Ideal for readers of fire behavior references and practitioners who want a hands-on method for estimating spotting distance in the field.
