线性稳定性分析方法在海洋小尺度不稳定研究中的应用
Linear stability analysis method and its application on small-scale instability processes in ocean
摘要
Abstract
The marine hydrodynamic profiles contain small-scale instability features,but they are difficult to quan-tify and characterize directly.As a commonly applied and well-developed classical analysis method,the linear sta-bility analysis(LSA)has the potential to reveal the instability features.This paper introduces the construction and implementation procedure of the LSA method in analyzing small-scale instabilities,and the possible factors that may influence the LSA results are discussed.Particularly,using the observational data at 142°E in the equatorial Pacific Ocean,we present the application of the method and show the instability properties,such as stratification,shear,growth rate and critical depths.The results show that the LSA method has good applicability and instruction in the study of small-scale instability processes in the ocean.关键词
