Purpose of Review

I sought to review the contributions of recent literature and prior foundational papers to our understanding of drought and fire. In this review, I summarize recent literature on drought and fire in the western USA and discuss research directions that may increase the utility of that body of work for twenty-first century application. I then describe gaps in the synthetic knowledge of drought-driven fire in managed ecosystems and use concepts from use-inspired research to describe potentially useful extensions of current work.

Recent Findings

Fire responses to climate, and specifically various kinds of drought, are clear, but vary widely with fuel responses to surplus water and drought at different timescales. Ecological and physical factors interact with human management and ignitions to create fire regime and landscape trajectories that challenge prediction.

Summary

The mechanisms by which the climate system affects regional droughts and how they translate to fire in the western USA need more attention to accelerate both forecasting and adaptation. However, projections of future fire activity under climate change will require integrated advances on both fronts to achieve decision-relevant modeling. Concepts from transdisciplinary research and coupled human-natural systems can help frame strategic work to address fire in a changing world.

美国西部的干旱和火灾：气候归因是否足够？

审查目的

我试图回顾最近的文献和先前的基础论文对我们对干旱和火灾的理解的贡献。在这篇评论中，我总结了最近有关美国西部干旱和火灾的文献，并讨论了可能会增加该工作体在二十一世纪的应用的研究方向。然后，我将描述受管理的生态系统中干旱驱动的火的综合知识中的差距，并使用基于用途的研究中的概念来描述当前工作的潜在有用扩展。

最近的发现

火灾对气候，特别是对各种干旱的反应很明显，但是在不同的时间尺度上，燃料对剩余水和干旱的反应差异很大。生态和物理因素与人为管理和点火相互作用，从而产生了挑战预测的火灾状况和景观轨迹。

概要

在美国西部，气候系统影响区域干旱的机制及其如何转化为火灾的机制需要更多关注，以加快预测和适应。但是，对气候变化下未来火灾活动的预测将需要在两个方面进行综合改进，以实现与决策相关的建模。跨学科研究和人与自然系统相结合的概念可以帮助制定战略工作，以应对不断变化的世界中的火灾。
