Real-world data, however, has been trickier to come by. Hurricanes – also known as tropical cyclones and typhoons, depending on where they originate – only appear sporadically, and can be difficult to study. Plus, these storms are often ignored if they don't directly impact upon on humans.
但现实中的数据更难获得。飓风又被称为热带气旋和台风,名字不同是因为发生地不同。飓风只是偶尔出现,很难研究。而且这些风暴如果没有对人类产生直接影响,通常会被忽视。
"The main hurdle we have for finding trends is that the data are collected using the best technology at the time," says Kossin.
Kossin说:“我们了解发展飓风趋势的主要障碍是搜集数据使用的都是当时最好的技术。”
"Every year the data are a bit different than last year, each new satellite has new tools and captures data in different ways, so in the end we have a patchwork quilt of all the satellite data that have been woven together."
“每年的数据都和前一年有点差异,每个新的卫星都有新的工具,获取数据的方式也不同。所以,最终我们把所有的卫星数据拼凑在一起。”
Thanks to computers though, which can help us to interpret satellite images of storms around the world, the team has now shown that from 1979 to 2017 there was a detectable trend toward stronger hurricanes – and this matches up consistently with greenhouse warming simulations.
