this is the main mechanism for the index cycle oscillations of zonal available potential energy variation.
平均有效位能变化的短期振动主要决定于平均有效位能与扰动有效位能的相互作用。
the baroclinic instability is the predominant mechanism for the growth of disturbances, and the mean available potential energy is the main energy source for the frontal meanders.
扰动成长的主要机制是斜压不稳定,锋面弯曲的主要能源是平均有效位能。
the available potential energy (ape) in the ocean can be transferred into kinetic energy of the ocean circulation.
