用大气环流模式CAM3.1和IAP AGCM4.0对模式中动力框架与物理过程之间的相互作用及响应关系进行了初步探讨。选用理想的物理过程（Held-Suarez强迫）及完整物理参数化方案，分别对两个模式积分了60 d。试验表明，动力框架与物理过程之间的相互响应在低纬对流层和高纬对流层中上层有着较大的区别。在低纬对流层，动力框架及物理过程产生的温度倾向都有着较大的变率，对总的温度倾向的变率均有较大的贡献，且二者之间为相互补偿的反相关关系；在高纬对流层的中上层，总的温度倾向的变化主要依赖于动力框架的贡献，物理过程造成的倾向变化很缓慢，可近似地看做定常的强迫，且物理过程产生的温度倾向与动力框架产生的温度倾向之间为正位相的响应关系。此外，还对各个物理参数化方案之间的相互作用及响应关系进行了分析。结果表明，在所有过程中，湿过程所引起的温度倾向的变化最为显著，对总的物理过程倾向的贡献也最大；在高纬地区，长波辐射冷却也有较大的变率；短波辐射加热率及垂直扩散加热率的变化相对较小；长波辐射冷却和短波辐射加热之间为近似负反馈的响应关系。
A study of the interaction and mutual response between dynamical core and physical parameterizations by atmospheric general circulation models CAM3.1 and IAP AGCM4.0 is presented. Both the two models were integrated 60 d with ideal physics (Held-Suarez forcing) and with full physical package, respectively. The results show that the mutual responses between dynamical core and physical parameterizations are very different in the troposphere at low latitudes and high latitudes. In the tropical troposphere, the variability of temperature tendency due to dynamical core and that due to physical parameterizations are both large and have significant contributions to the variability of total temperature tendency, and they are in inverse correlation to compensate each other. In the polar middle and upper troposphere, the variability of total temperature tendency mainly relies on the tendency due to dynamical core, while the variation of temperature tendency due to physics is very slow, which can be seen as a stationary forcing. Unlike the tropical regions, there is a positive correlation between the temperature tendency due to dynamics and that due to physics in Polar regions. Moreover, the interactions and mutual responses between the individual physical parameterizations are also analyzed. The results show that the variation of temperature tendency due to moist process is the largest of all the physical parameterizations, and it contributes most to the total temperature tendency due to physics. The variation of temperature tendency due to long wave radiation is also large at high latitudes, while the variation of temperature tendency due to short wave radiation and that due to vertical diffusion are relatively small. There is a negative feedback between the cooling rate of long wave radiation and the heating rate of short wave radiation.
