The collaborative research will be guided by two notions based on the PI's ongoing 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.

合作研究将以两个概念为指导，这两个概念基于PI正在进行的关于Madden Julian Oscillation（MJO）的研究：（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SST变化对MJO中表面潜热/感热通量的一般作用的修改。根据这两个准则，拟议的研究将（i）调查海洋的响应和反馈的MJO的两个概念模型的背景下，基于观测和（ii）探讨海洋反馈机制的框架内研究的一般作用的表面热通量的MJO。为了深入了解海气相互作用的大尺度物理过程，该研究项目将首先分别关注海洋对MJO的响应和反馈，然后再进行任何耦合尝试。这项工作很重要，因为它将产生对MJO和ENSO之间的相互作用的见解，这将对ENSO的更好的季节性预测产生影响。
