Hi Reddit。我是 Mo Tamman，路透社调查数据与计算编辑，我提出了我们关于热风暴新系列报道的概念。
Hi Reddit. I'm Mo Tamman, an investigative data and computational editor at Reuters, and I developed the concept for our new series on heat storms.
科学家们谈论地球升温超过工业化前水平 2 摄氏度的风险，但这对大多数人来说意义不大。热浪不同。每个人都已经理解热浪，因此观察热浪发生了怎样的变化——而且，天哪，它们变化巨大！——可以展示我们的气候正在发生什么。
Scientists talk about the risks of the planet warming more than 2 degrees Celsius above pre-industrial levels, but that means little to most people. Heat waves are different. Everyone already understands them, so looking at how they have changed — and, boy, have they changed! — can show what’s happening to our climate. The problem was that there was no standard definition of a heat wave.
问题在于没有热浪的标准定义。例如，美国国家气象局采用连续两天或以上异常炎热天气，而英国、法国、西班牙和澳大利亚采用三天。这种定义不一使得几乎无法判断热浪在全球范围内是否变得更加频繁。
For example, the US National Weather Service uses two or more days of abnormally hot weather, while the UK, France, Spain and Australia use three. Such dueling definitions made it nearly impossible to tell whether heat waves are becoming more common worldwide. So in consultation with two dozen climate scientists, meteorologists and weather researchers, we developed a universal definition of a heat wave and identified a new concept: the heat storm.
因此，在咨询了二十多位气候科学家、气象学家和天气研究人员后，我们制定了一个通用的热浪定义，并确立了一个新概念：热风暴。
Heat wave: five or more days in a row when a location's daily high is in the hottest 10% of its 1961–1990 range for that day of the year.
热浪：某地日最高气温连续五天或以上处于该日历日 1961–1990 年期间最热 10% 范围内。
Heat storm: a heat wave that, at its peak, covers at least 1% of the planet, roughly half the size of Canada.
热风暴：在其峰值时覆盖至少 1% 地球表面的热浪，面积约相当于加拿大的一半。
Calling something that big a "heat wave" would be like calling a monsoon a rain shower.
把这么大规模的现象称为“热浪”，就像把季风称为阵雨一样。我们还像给飓风命名一样，为每个热风暴命名。
We also give each heat storm a name, as is done with hurricanes. I will answer questions from 1-2 pm ET on Thurs, Oct. 22.
我将于美东时间周四（10 月 22 日）下午 1 点至 2 点回答问题。欢迎就数据、方法论、报道或我的同事 Ben Welsh 和 Charlie Szymanski 构建的实时热风暴追踪器提问。PROOF：阅读报道并了解我们的方法论：
