Conventional climate models continue to struggle to properly represent large-scale tropical moist convective systems including convectively coupled equatorial waves) and the Madden Julian Oscillation (MJO). Because these disturbances have global impacts on weather and climate through atmospheric and oceanic teleconnections, this casts a shadow of doubt on the reliability of climate prediction on different timescales ranging from intraseasonal to seasonal and longer. This collaborative project has the goals of improving understanding of the dynamics of these disturbances, and enhancing the ability to simulate them by using a new Lagrangian atmospheric model that simulates atmospheric circulations by predicting motions of individual air parcels. Educational impacts of this project will include further development of climate modeling capabilities at Yale and Susquehanna Universities, which will benefit both undergraduate and graduate students by introducing them to cutting edge techniques in atmospheric modeling and convective parametrization. In addition there is a plan to educate the general public about the fundamentals of weather and climate modeling. Thus the project has substantial broader impacts.

传统的气候模式仍然很难正确地代表大尺度热带湿对流系统，包括对流耦合的赤道波和马登朱利安振荡。由于这些扰动通过大气和海洋遥相关对天气和气候产生全球性影响，这使人们对从季节内到季节和更长时间尺度的气候预测的可靠性产生了怀疑。这一合作项目的目标是提高对这些扰动的动态的理解，并通过使用新的拉格朗日大气模型来提高模拟这些扰动的能力，该模型通过预测单个气团的运动来模拟大气环流。该项目的教育影响将包括进一步发展耶鲁大学和萨斯奎汉纳大学的气候建模能力，这将使本科生和研究生受益，向他们介绍大气建模和对流参数化方面的尖端技术。此外，还有一项计划，教育公众了解天气和气候建模的基本原理。因此，该项目具有相当广泛的影响。
