In this collaborative project, the principal investigators will address some key questions relating to the dynamical interaction between the stratosphere and the troposphere on both, climate and weather forecasting timescales. In particular, the PIs will study how perturbations in the stratosphere may be able to exert an influence on the tropospheric circulation. In a three-pronged approach, reanalyses will be examined, simulations with idealized three-dimensional dynamical models, and simulations with a comprehensive troposphere-stratosphere model will be performed. Graduate students will participate in this research.

在这一合作项目中，主要研究人员将解决与平流层和对流层在气候和天气预报时间尺度上的动力相互作用有关的一些关键问题。特别是，PI将研究平流层的扰动如何能够对对流层环流产生影响。将采取三管齐下的办法，审查再分析，利用理想化三维动力学模型进行模拟，并利用对流层-平流层综合模型进行模拟。研究生将参与这项研究。
