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

基于目前对麦登朱利安涛动（MJO）的研究，本文将以两个概念为指导：(a) MJO的海气相互作用机制取决于MJO的详细结构；(b)海洋对MJO的反馈应被视为海温变化对MJO中地表潜热/感热通量一般作用的修正。按照这两个准则，拟议的研究将(i)在基于观测的两个MJO概念模式的背景下研究海洋对MJO的响应和反馈，（ii）在研究表面热通量在MJO中的一般作用的框架内探索海洋反馈机制。为了深入了解海气相互作用的大尺度物理过程，研究项目将首先分别关注海洋对MJO的响应和反馈，然后再尝试进行耦合。这项工作很重要，因为它将提供MJO和ENSO之间相互作用的见解，这将对更好的ENSO季节预报产生影响。

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.
