What could fires in Central America have to do with the deadliest outbreak of tornadoes in recent U.S.history?

隐藏原文=

More than you might think, according to a new study.

"What's happening is that this smoke, it interacts with clouds and with solar radiation."

点击显示原文

隐藏原文=

Smoke consists of tiny particles, called aerosols, which can have complicated effects on weather.

点击显示原文

隐藏原文=

So Saide used a model to explore whether these particles influenced the tornado outbreak of April 27.

点击显示原文

隐藏原文=

He found smoke made twisters more likely to strike, and more ferocious when they did.

点击显示原文

隐藏原文=

However, at the moment, weather forecasts don't consider aerosol particles.

"This is difficult because weather models need to be finished very fast, because you want weather predictions for today, not for tomorrow.

隐藏原文=

And including these aerosols makes it slower."

点击显示原文

隐藏原文=

But Saide thinks it's worth it.

点击显示原文

隐藏原文=

He says understanding the role of smoke and other airborne particles will help forecasters predict when weather conditions might change from dreary to deadly.

Thanks for the minute, for Scientific American's 60-Second Science. I'm Julia Rosen.
