Internal waves propagate in the volume of the ocean, and are influenced by density variations, as well as the Earth’s rotation. When they break, they mix and move water up from the cold abyss, and heat down from the sun-bathed surface. When forced by wind, internal waves are very active in the upper ocean, participate in direct atmosphere-ocean exchanges, and might extract energy out of the large-scale vortices that contain the majority of the ocean’s kinetic energy. These vortices are called geostrophic and are characterized by a balance between pressure gradients and the Coriolis force.

内波在海洋体积中传播，并受到密度变化和地球自转的影响。当它们破裂时，它们混合并将水从寒冷的深渊中移动，并从阳光沐浴的表面加热。当受到风的推动时，内波在上层海洋中非常活跃，参与直接的大气-海洋交换，并可能从包含大部分海洋动能的大规模漩涡中提取能量。这些涡旋被称为地转涡旋，其特征是压力梯度和科里奥利力之间的平衡。
