National and regional preparedness level (PL) designations support decisions about wildfire risk management. Such decisions occur across the fire season and influence pre-positioning of resources in areas of greatest fire potential, recall of personnel from off-duty status, requests for back-up resources from other areas, responses to requests to share resources with other regions during fire events, and decisions about fuel treatment and risk reduction, such as prescribed burning. In this paper, we assess the association between PLs assigned at national and regional (Northwest) scales and a set of predictors including meteorological and climate variables, wildfire activity and the mobilisation and allocation levels of fire suppression resources. To better understand the implicit weighting applied to these factors in setting PLs, we discern the qualitative and quantitative factors associated with PL designations by statistical analysis of the historical record of PLs across a range of conditions. Our analysis constitutes an important step towards efforts to forecast PLs and to support the future projection and anticipation of firefighting resource demand, thereby aiding wildfire risk management, planning and preparedness.

高严重性野火潜力——将气象、气候、资源需求和野火活动与备灾水平联系起来

国家和区域准备级别 (PL) 指定支持有关野火风险管理的决策。此类决定在整个火灾季节发生，并影响在最有可能发生火灾的地区预先部署资源、从休班状态召回人员、从其他地区请求后备资源、响应在火灾期间与其他地区共享资源的请求。火灾事件，以及有关燃料处理和风险降低的决定，例如规定的燃烧。在本文中，我们评估了在国家和区域（西北）尺度分配的 PL 与一组预测因子之间的关联，包括气象和气候变量、野火活动以及灭火资源的动员和分配水平。为了更好地理解在设置 PL 时应用于这些因素的隐式权重，我们通过对各种条件下 PL 的历史记录进行统计分析，辨别与 PL 名称相关的定性和定量因素。我们的分析是朝着预测 PL 和支持未来预测和预测消防资源需求迈出的重要一步，从而有助于野火风险管理、规划和准备。
