What is a Rossby wave train? Scientists explain how Antarctica gained nearly 700 billion tons of ice - The surprising atmospheric pattern that disrupted normal weather, delivered extraordinary snowfall and and temporarily reversed the continent’s long-term ice loss

In a surprising turn, Antarctica temporarily gained ice mass, attributed to warm tropical ocean currents. These warm waters triggered atmospheric shifts that led to significant snowfall across the region. A Rossby wave train transported these phenomena over vast distances to East Antarctica. However, this short-lived ice gain does not indicate a permanent recovery for the continent, emphasizing the need for understanding these remote interactions for accurate sea-level rise predictions.
