Decades of global research have sparked the big question: can we really control the weather? According to a study published today in the journal Nonlinear Processes of Geophysics, this may soon be our new reality.
Researchers from the RIKEN Center for Computational Science have used computer simulations to show that extreme weather phenomena can be controlled and modified by making small adjustments to variables in the weather system. They did this using a system called a “butterfly attractor” in chaos theory, which has one of two states— just like the wings of a butterfly— and switches back and forth between the two states depending on small changes in certain conditions. The study’s findings promise multiple applications in the future, where weather events can be better controlled, including the effects of climate change.
The butterfly attractor was first proposed by mathematician and meteorologist Edward Lorenz, one of the founders of modern chaos theory. According to Lorenz, even the most minute, butterfly-scale changes to his computer weather models caused a range of weather outcomes from bright skies to raging storms, with no way to predict the final outcome. Since Lorenz first presented his study in 1972, his theory about the butterfly effect came to be widely popular and remains so even today. It includes the metaphor that a butterfly flapping its wings in Brazil can cause a tornado in Texas.
