Arizona Olympians propose new way to protect against extreme weather events
Researchers from Arizona State University have proposed a new approach to combating extreme weather events, Zamin.uz reports.
Instead of broadly interfering with the climate system, scientists are exploring whether small, targeted interventions during sensitive stages of development could prevent disasters. This approach leverages the atmosphere’s internal dynamics to steer its behavior.
The research builds on the well-known butterfly effect from chaos theory. Because the atmosphere is a complex, nonlinear system, even tiny changes in its initial state can significantly influence large-scale future developments.
According to the scientists, the trajectory and intensity of hurricanes, cold snaps, or heatwaves could potentially be adjusted before they gain destructive force. To test this concept, specialists used Aurora, a large-scale AI model trained on atmospheric data.
This system analyzes vast volumes of climate data to identify the most favorable time and location for intervention. During experiments, real historical weather events were replayed and subjected to artificial influences.
The results proved more effective than expected. For instance, when modeling Hurricane Sandy—which caused massive damage in 2012—a precisely calculated intervention applied several days before landfall altered the storm’s path by up to 300 kilometers.
Such a shift would be sufficient to steer the hurricane away from major metropolitan areas like New York. Additionally, other outcomes emerged during modeling.
In the 2021 Texas cold snap, it was found that minimum temperatures could potentially be raised by about 10 degrees through minimal intervention. It was also shown that the intensity of precipitation in atmospheric rivers—responsible for severe flooding—could be reduced by up to 5 percent.
Scenarios involving small influences on high-altitude atmospheric currents that steer hurricane movement were validated. The researchers emphasize that traditional protective measures are no longer sufficient to cope with the growing damage caused by climate change.
According to estimates, extreme weather events in 2024 alone caused approximately $417 billion in global economic damage. As global warming increases both the frequency and intensity of such events, new approaches are urgently needed.
Although the project currently exists only in computer simulations, plans are underway to apply it in practice using cloud-seeding technology. This method allows control over precipitation amounts by altering cloud composition.
Scientists express hope that in the future, this approach could become an effective tool for mitigating hurricanes, droughts, and extreme heat events.
