Polar Cyclone Identification from 4D Climate Data in a Knowledge-Driven Visualization System
Arctic cyclone activity has a significant association with Arctic warming and Arctic ice decline. Cyclones in the North Pole are more complex and less developed than those in tropical regions. Identifying polar cyclones proves to be a task of greater complexity. To tackle this challenge, a new metho...
