American scientists from the National Center for Atmospheric Research and Florida State University have discovered a new climate factor that could weaken the formation of powerful hurricanes in the Atlantic Ocean. The study was published in the scientific journal broadcasting Journal of Advances in Earth Systems Modeling (JAMES).
The formation of hurricanes and other tropical cyclones, known as cyclogenesis, is a complex process in which small-scale weather events and large-scale atmospheric events occur simultaneously. This complexity makes tropical cyclone formation difficult to study and model.
Most climate models provide only a grainy picture of local weather events, making it difficult to study the role of individual components, such as humidity, that come together to create cyclogenesis.
The team performed digital simulations of Atlantic storms and found that increased air moisture produces weaker, slower atmospheric waves that act as the “seeds” of Atlantic storms.
The addition of moisture changes the position of storm clouds at the front, making it harder for waves to grow. The increased moisture also slows the movement of the air mass, weakening the formation of hurricane embryos once they reach the eastern Atlantic waters.
The conditions that lead to tropical cyclone formation are complex, but researchers hope these new modeling techniques will lead to better predictions.
Previously experts warned About the risk of severe hurricanes in the Atlantic in 2024.
