Fill et al. (Global Change Biology, 25, 3562–3569, 2019) reported significant increases in dry season length over the past 120 years in the Southeast US, suggesting increased wildfire risk in a region associated with a frequent fire regime. We identified two flaws that call into question the findings and their relevance to regional wildfire risk. First, with the exception of Florida, there is little evidence for a climatologically meaningful ‘dry season’ in the Southeast because most areas experience relatively evenly distributed monthly precipitation. Second, the sampling method used to derive Cumulative Rainfall Anomalies does not appear to actually reflect a bootstrap sample as described.

美国东南部有旱季吗?

Fill等。(Global Change Biology,25,3562-3569,2019)报告说,过去120年来,美国东南部的旱季时长显着增加,这表明与频繁发生火灾的地区相比,野火风险增加。我们发现了两个缺陷,这些缺陷使研究结果及其与区域野火风险的相关性产生了疑问。首先,除了佛罗里达州外,几乎没有证据表明东南部具有气候学意义的“干旱季节”,因为大多数地区的月降水量分布相对均匀。其次,用于得出累积降雨异常的采样方法似乎并未真正反映出所述的自举样本。
