Short summary
Understanding seasonal changes in Greenland glaciers is vital for studying long-term trends. We use a simple model and high-resolution observation to reveal how multiple processes influence seasonal glacier velocity either alternately or simultaneously each year. Additional tests suggest a steepening glacier surface increases sensitivity of the surface velocity to terminus changes. Our approach can be applied to other glaciers decompose seasonal changes of glacier velocity.
