The pitfalls of applying the commonly used definition of available gravitational potential energy (AGPE) to the world oceans are re-examined.It is proposed that such definition should apply to the meso-scale problems in the oceans, not the global scale.Based on WOA98 climatological data, the meso-scale AGPE in the world oceans is estimated.Unlike previous results by Oort et al., the meso-scale AGPE is large wherever there is a strong horizontal density gradient.The distribution of meso-scale AGPE reveals the close connection between the baroclinic instability and the release of gravitational potential energy stored within the scale of Rossby deformation radius.
