从一个特别关注的作用，压力地形的相关性在沿海动力学，异想天开的术语“海王星效应”出现，一个更广泛和更强大的背景展开。很明显，这种效应的强度可以与风或温盐强迫相媲美，但即使是最强大的计算机模型也不存在或严重损坏。一种新的方法考虑了理想化的统计力学，然后考虑到诸如风或温差等施加的力将使海洋的状态远离较高的熵配置。由于偏离高熵值而产生的非平衡趋势可作为未解决的涡流效应的参数。引入传统的海洋模型导致了很大的差异，显着提高模型的技能，对全球库存的长期流速计记录测量。
Beginning from a particular concern about the role of pressure-topography correlations in coastal dynamics, for which the whimsical term “Neptune effect” arose, a broader and more powerful context unfolded. It has become clear that this effect has strength comparable to wind or thermohaline forcing, yet it is absent or grossly corrupted in even the most powerful computer models. A novel approach considers idealized statistical mechanics, then takes account that applied forces such as wind or thermohaJine will draw the state of the ocean away from a higher entrophy configuration. Nonequilibrium tendencies which arise due to departure from higher entrophy serve to parameterize unresolved eddy effects. Introduction into conventional ocean models leads to large differences which markedly improve model skill measured against a global inventory of long term current meter records.
