9316633 Ledley This project is the application of an existing generalized sea ice model to the particular regional setting of the Ross Sea. A smaller-scale version of the same model will be nested within the regional model to represent McMurdo Sound. The simulated sea ice fields will be validated through a comparison with available observations, and used to assess the impact of sea ice on ocean-atmosphere energy exchange processes. After the model is adapted for the Ross Sea setting, and the simulated seasonal sea ice variations have been validated, a series of sensitivity studies will be carried out. These will be designed to examine the response of the sea ice to changes that may occur in the regional climate system on both short and long time scales. Finally, the model will be extended by nesting a finer grid submodel in the Ross Sea model in order to examine the effects of katabatic winds and synoptic weather variations on the sea ice distribution. ***

9316633 Ledley该项目是将现有的广义海冰模型应用于罗斯海的特定区域环境。 同一模型的较小规模版本将嵌套在区域模型中，以代表麦克默多湾。 模拟的海冰场将通过与现有观测结果的比较进行验证，并用于评估海冰对海洋-大气能量交换过程的影响。 在该模式适用于罗斯海的设置，并模拟的季节性海冰变化已被验证后，将进行一系列的敏感性研究。 这些试验将用于研究海冰对区域气候系统在短期和长期尺度上可能发生的变化的反应。 最后，该模式将通过嵌套一个更精细的网格子模式在罗斯海模式，以检查下降风和天气变化对海冰分布的影响进行扩展。 ***
