The Impact of Tides on Simulated Landfast Ice in a Pan-Arctic Ice-Ocean Model

摘要: The impact of tides on the simulated landfast ice cover is investigated. Pan‐Arctic simulations are conducted with an ice‐ocean (CICE‐NEMO) model a modified rheology and grounding scheme. reference experiment (without tides) indicates there overestimation extent in regions strong such as Gulf Boothia, Prince Regent Inlet Lancaster Sound. addition simulation clearly leads to decrease some tidally active regions. This numerical more line observations all studied. Thermodynamics changes cannot explain lower area when tidal forcing included. We rather demonstrate that this dynamically driven by increase ocean‐ice stress due tides. Plain Language Summary Landfast sea immobile near coast for certain period time. coastal can stay at rest because it attached and/or anchored floor shallow water. To study ice, we used represents physical interactions between atmosphere, ocean ice. compared two done model: one without includes exhibits which observations. adding dynamical process; currents constantly set motion, preventing become landfast.
