作为发展一般行星使用的大气环流模式的一个初步步骤，GISS Model 1 GCM的一个简化版本已经在不同的旋转周期运行，以研究快速和缓慢旋转行星的动力学机制之间的差异。为了隔离动力学过程，水文循环被抑制，大气被迫与常年平均太阳能加热。除自转周期外，所有其他参数都保持其地面值不变。试验进行了10天，1，2，4，8，16，64和256天的旋转周期。结果是在定性协议与类似的实验进行了以前与其他GCM和金星GCM模拟的某些方面。当Rossby形变半径达到行星尺度时，随着自转速率的减小，能量从斜压向准正压转变。哈德利环流向极地扩展，取代涡旋成为大尺度热传输的主要模式。
Abstract As a preliminary step in the development of a general circulation model for general planetary use, a simplified version of the GISS Model 1 GCM has been run at various rotation periods to investigate differences between the dynamical regimes of rapidly and slowly rotating planets. To isolate the dynamical processes, the hydrologic cycle is suppressed and the atmosphere is forced with perpetual annual mean solar heating. All other parameters except the rotation period remain fixed at their terrestrial values. Experiments were conducted for rotation periods of ⅔, 1, 2, 4, 8, 16, 64 and 256 days. The results are in qualitative agreement with similar experiments carded out previously with other GCMs and with certain aspects of one Venus GCM simulation. As rotation rate decreases, the energetics shifts from baroclinic to quasi-barotropic when the Rossby radius of deformation reaches planetary scale. The Hadley cell expands poleward and replaces eddies as the primary mode of large-scale heat transport....
