通过一个简化的大气-海洋耦合气候模式的理想化实验，研究了海洋动力学、地形及其相互作用对大气风暴路径的控制。研究了北半球冬季平均风暴轴的准稳定状态。实验从没有山脉和海洋动力学的背景状态开始，分不同的阶段包括地形和动态海洋，以获得更逼真的控制模拟。海洋动力学、地形及其非线性相互作用分别对风暴路径和海洋表面热力强迫进行了识别。模式研究表明，大气风暴路径是气候系统的一个强大特征，即使没有地形强迫或海洋热输送，也发生在中纬度地区。海洋动力通常导致风暴路径和大气向北热量输送的最大值向极地移动，并导致大西洋上空向东北倾斜。这种极移与海洋额外的热量输送和大洋盆地西侧海面温度梯度的收紧有关。地形强迫引起沿路径的变化，使大陆上空的风暴路径减弱，并导致西太平洋上空向东北倾斜，这与青藏高原产生的定常行星波列有关。海洋动力和地形强迫之间的相互作用起着局部性的作用，增强了大西洋和太平洋之间的对比。对强迫的大部分反应是由涡旋调节的，而瞬时的涡旋有助于传播地形和海洋强迫的影响。
The control of atmospheric storm tracks by ocean dynamics, orography, and their interaction is investigated using idealized experiments with a simplified coupled atmosphere–ocean climate model. The study focuses on the quasi–steady state for the storm tracks in the Northern Hemisphere winter mean. The experiments start with a background state without mountains and ocean dynamics, and in separate stages include orography and a dynamic ocean to obtain a more realistic control simulation. The separate effects of ocean dynamics, orography, and their nonlinear interaction are identified for the storm tracks and the surface thermodynamic forcing over the ocean.The model study suggests that atmospheric storm tracks are a robust feature of the climate system, occurring at midlatitudes even if there is no orographic forcing or ocean heat transport. Ocean dynamics generally lead to a poleward shift in both the storm track and the maximum in atmospheric northward heat transport and induce a northeastward tilt over the Atlantic. This poleward shift is linked to the extra heat transport by the ocean and the tightening of sea surface temperature gradients on the western side of ocean basins. Orographic forcing causes along-track variability with a weakening of the storm track over the continents and induces a northeastward tilt over the western Pacific, which is associated with a stationary planetary wave train generated by the Tibetan Plateau. The interaction between ocean dynamics and orographic forcing plays a localized role, enhancing the contrast between the Atlantic and Pacific. Much of the response to the forcing is eddy mediated and transient eddies help to spread the influence of orographic and ocean forcing.
