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

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

Researchers found that smoke, wafting north from the Gulf of Mexico,

worsened the already stormy weather brewing across the southeastern U.S. on April 27, 2011. That afternoon, 122 twisters tore across the country, killing

313 people. It's not that the outbreak happened because of the smoke. Pablo Saide of the University

of Iowa and the author of a new study published in the journal Geophysical

Research Letters.

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

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

Society used a model to explore whether these particles influenced

the tornado outbreak of April 27th. He found smoke-made twisters more likely to strike and more

ferocious when they did. 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. And including these aerosols, it makes it slower.

But Saeedi thinks it's worth it. He says understanding the role of smoke and other airborne particles

will help forecasters predict when weather conditions might change, from dreary to deadly.
