Summary Excerpt Details

This paper describes and compares conceptually the Fire Weather Index (FWI) system of Canada and the National Fire Danger Rating System (NFDRS) of the USA. The relatively simple FWI system rates fire danger for all Canada and is based on empirical field-data derived from a single fuel type. The laboratory-based NFDRS, in contrast, allows more specification for distinct fire danger areas and models fuel moisture more abstract and in different classifications. Relative strengths and weaknesses with regard to the vegetative conditions in the particular country are discussed. The use of empirical data and the good and simple representation of soil moisture are the major strengths of the FWI system. The NFDRS wins through its possibility to model specifically a distinct fire danger area and through the consideration of live fuel moisture content. The conclusion of this paper is that both systems can benefit from each other. A combination of the simplicity of the FWI and specialization on a distinct area through the site descriptors similar to the ones of the NFDRS is proposed.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This paper presents a comparative analysis of the Fire Weather Index (FWI) system used in Canada and the National Fire Danger Rating System (NFDRS) implemented in the United States. The objective is to provide a comprehensive description and comparison of these systems, highlighting their strengths and weaknesses. The paper aims to identify potential areas for improvement and suggest a combined approach that incorporates the best features of both systems.

  • Comparison of Fire Danger Rating Systems (FWI and NFDRS)
  • Analysis of System Structures and Model Bases
  • Evaluation of Strengths and Weaknesses of Each System
  • Potential for Combining Features of FWI and NFDRS
  • Importance of Fire Danger Rating for Wildfire Management

Zusammenfassung der Kapitel (Chapter Summaries)

  • Introduction: This section provides a general definition of fire danger and its significance in wildfire management. It introduces the two systems under comparison, the Canadian Fire Weather Index (FWI) and the American National Fire Danger Rating System (NFDRS), and outlines the scope of the paper.
  • Description of the Canadian Forest Fire Weather Index (FWI): This chapter details the structure and workings of the FWI system. It explains the system's reliance on empirical field data and its focus on a single standard fuel type. The chapter describes the key components of the FWI, including the fuel moisture codes (FFMC, DMC, and DC) and the indices that measure initial spread (ISI) and fuel build-up (BUI).

Schlüsselwörter (Keywords)

The primary keywords and focus topics of this paper include fire danger rating, wildfire management, Fire Weather Index (FWI), National Fire Danger Rating System (NFDRS), fuel moisture, fire behavior, empirical data, model comparison, and system optimization.
