Collaborative Research: A Modeling Study of Air-Sea Interaction Associated with the Madden-Julian Oscillation

合作研究将以目前对Madden Julian涛动(MJO)的研究为基础的两个概念为指导：(A)MJO的海气相互作用机制取决于MJO的详细结构，以及(B)海洋对MJO的反馈应被视为通过SST变化修改表面潜热/感热通量在MJO中的一般作用。根据这两项准则，拟议的研究将(1)在基于观测的两个海洋联合组织概念模式的背景下调查海洋对海洋联合组织的响应和反馈；(2)在研究海洋表面热通量在海洋联合组织中的一般作用的框架内探索海洋反馈机制。为了彻底了解海气相互作用的大尺度物理过程，在进行任何耦合尝试之前，该研究项目将首先分别关注海洋对MJO的响应和反馈。这项工作很重要，因为它将对MJO和ENSO之间的相互作用产生深刻的认识，这将对更好地预测ENSO的季节性产生影响。

The collaborative research will be guided by two notions based on current research on the Madden Julian Oscillation (MJO): (a) mechanisms for air-sea interaction of the MJO depend on the detailed structure of MJO, and (b) oceanic feedback to the MJO should be viewed as a modification of the general role of surface latent/sensible heat fluxes in the MJO by SST variation. Following these two guidelines, the proposed research will (i) investigate the oceanic response and feedback to the MJO in the context of two MJO conceptual models based on observations and (ii) explore the oceanic feedback mechanisms within the framework of studying the general role of surface heat fluxes in the MJO. To achieve a thorough understanding of large-scale physical processes of air-sea interaction, the research project will first focus separately on the oceanic response and feedback to the MJO, before any attempt of coupling is made. The work is important because it will yield insights on the interaction between the MJO and ENSO, this will have implications for better seasonal forecasting of ENSO.
