Cessi 9618126 A hierarchy of quasi-geostrophic (QG) models (barotropic, two-layer baroclinic, baroclinic with feedback between sea surface temperature and wind stress) will be used to examine the time-dependence and stability of a non-linear system forced by steady winds. Of particular interest is the degree of intrinsic long-term variability as a function of forcing to dissipation ratio and in understanding how sea surface temperature/wind stress feedbacks produce new modes of low- frequency variability.

Cessi 9618126准地转（QG）模式（正压，两层斜压，斜压与海表面温度和风应力之间的反馈）的层次将被用来检查的时间依赖性和稳定性的非线性系统强迫定常风。特别令人感兴趣的是作为强迫耗散比函数的内在长期变率的程度，以及了解海表面温度/风应力反馈如何产生新的低频变率模式。
