A new way to see inside a hurricane
Researchers at The University of Texas at Arlington have created a mathematical model to identify and analyze vortices, the rotating structures at the heart of hurricanes. The National Oceanic and Atmospheric Administration is now using the model to monitor hurricane development worldwide.
Researchers at The University of Texas at Arlington have developed a mathematical model called Liutex to identify and analyze vortices in hurricanes. This breakthrough could revolutionize hurricane forecasting as most vorticity in hurricanes is due to shear rather than rotation. Professor Chaoqun Liu has spent decades perfecting Liutex, which separates pure rotation from nonrotational shear.
Traditional methods struggle to distinguish vortices from nonrotational shear, likening it to identifying an apple by examining an orange. NOAA now uses Liutex to monitor hurricane development globally. The model's uniqueness lies in its ability to quantify vortex rotation, offering a new perspective on hurricane structure and behavior.
Beyond meteorology, Liutex is being applied to cardiovascular research, where blood flow is analogous to fluid flow. This versatility opens up a multitude of research opportunities across various fields, promising new discoveries in understanding hurricane formation, strengthening, and potential medical applications.
