通过研究一对热耦合旋转斜压环空系统的动力学，实验研究了大气环流的流体动力学模拟中的同步现象。在周期和混沌两种状态下，系统之间的耦合都是众所周知的主从结构。利用相动力学分析等同步工具研究了耦合系统的动力学行为，并根据耦合强度和参数失配的不同，论证了耦合系统的相位同步和不完全同步。
Synchronization phenomena in a fluid dynamical analogue of atmospheric circulation is studied experimentally by investigating the dynamics of a pair of thermally coupled, rotating baroclinic annulus systems. The coupling between the systems is in the well-known master-slave configuration in both periodic and chaotic regimes. Synchronization tools such as phase dynamics analysis are used to study the dynamics of the coupled system and demonstrate phase synchronization and imperfect phase synchronization, depending upon the coupling strength and parameter mismatch.
