系统地阐述了北太平洋Rossby波在卫星观测、理论扩展及模型应用3个方面的研究成果。随着卫星观测技术的发展,明显地探测到海表面信号的Rossby波特征,且观测到波速在热带外大于自由Rossby波理论值。为解释这个波动加速现象,在自由Rossby波理论的基础上,考虑了大气强迫、非静止基流及海底地形等因子的作用,使得Rossby波的波动理论得到了扩展。而关于风应力强迫Rossby波的线性理论模型主要有3类:一阶斜压Rossby波模型、局地Ekman抽吸模型和Sverdrup平衡模型。这些模型被广泛地应用到北太平洋海表面高度和温度/密度跃层深度等要素变化的机理研究中,得到了不同的模型在大洋的不同区域有不同的作用等结论。最后,对线性Rossby波研究存在的问题进行了初步探讨,提出了需要进一步解决的新课题。 This paper systematically expounds the research results of Rossby waves in the North Pacific Ocean in terms of satellite observations, theoretical extensions and model applications. With the development of satellite observations, the Rossby wave features of the sea surface signals are clearly detected and the observed wave velocities are greater than those of free Rossby waves outside the tropics. To explain this phenomenon, based on the free Rossby wave theory, the effects of atmospheric forcing, non-stationary base flow and submarine topography are taken into account, which make the wave theory of Rossby wave broaden. There are mainly three types of linear theoretical models for wind-induced forced Rossby waves: the first-order baroclinic Rossby wave model, the local Ekman pumping model, and the Sverdrup equilibrium model. These models are widely used in the study of the mechanism of elemental variations in sea surface height and temperature / density thermocline in the North Pacific Ocean. The results show that different models have different effects in different regions of the ocean. Finally, the problems existing in the research of linear Rossby wave are discussed preliminarily, and new topics that need to be further solved are proposed.
