论文摘要
在本报告中，我们为挪威地球系统模型Noresm的长期仿真制定了一种模拟方法。在此中，沉积物反复脱钩并耦合到海洋模型（Blom/Ihamocc），这是一个称为爆发耦合的过程。通过此，海洋（海水和沉积物）变为近似稳态。我们表明，仅该模型必须运行至少50000年才能处于近似稳态状态。通过爆发耦合，这可以在计算合理的时间内完成（按一周的时间为单位）。该方法可用于在数十万年内生成沉积物，因此，它不仅对当今的模拟，而且对古气候研究也很有用。
In this report we set forth a simulation method for long-term simulations of NorESM, the Norwegian Earth System Model. In this the sediment is repeatedly decoupled and coupled to the ocean model (BLOM/iHAMOCC), a process called burst coupling. Through this, the ocean (seawater and sediment) is brought into an approximate steady state. We show that just the model has to run at least 50000 yr to get in an approximate steady state. With burst coupling this can be done in a computationally reasonable time (wall time in the order of one week). The method can be used to generate the sediment over hundreds of thousands of years, so it is useful not only for present-day simulations but also for paleo-climatological studies.
