Long-Term Climate Change Studies with Energy Balance Models

气候变化的物理机制尚不清楚 明白 该提案要求支持分析冰川- 间冰期气候变化的一系列实验， 能量平衡模型（EBM）。 PI将使用耦合 气候-海冰模式（CCSI）评估：1）冰的影响 运输和铅对极地和全球气候的影响，以及2） 米兰科维奇太阳辐射变化对气候的影响 的CCSI 将与大陆冰盖模型相结合， 研究冰盖形成和结冰的过程 板响应米兰科维奇太阳辐射变化。 这 研究计划将有助于描绘气候的影响， 海冰分布的变化，并有助于隔离 大陆冰盖生长和衰退的机制。

The physical mechanisms of climate change are not yet well understood. This proposal requests support to analyze glacial- interglacial climate change using a series of experiments with a series of energy balance models (EBM). The PI will use a coupled climate-sea ice model (CCSI) to evaluate: 1) the influence of ice transport and leads on polar and global climate and 2) the impact of Milankovitch solar radiation variations on climate. The CCSI will then be coupled with a continental ice sheet model to examine the processes involved in ice sheet initiation and ice sheet response to Milankovitch solar radiation variations. This research program will help to delineate the effects on climate of changes in sea ice distribution and help to isolate the mechanisms of continental ice sheet growth and decay.
