Scientists have identified low-level jets (LLJs) as a key factor in the rapid melting of the Thwaites Glacier, also known as the "Doomsday Glacier." These high-speed winds near the surface are prevalent along the Amundsen Sea coast.
The study, published in Advances in Atmospheric Sciences, indicates that LLJs are frequently reinforced by passing storms. Simulations show these winds extend over large areas of the Amundsen Sea embayment.
The Thwaites Glacier contributes approximately 4% to global sea level rise, losing 50 billion tons of ice annually. Its collapse could raise sea levels by up to 3.3 meters, threatening coastal cities.
