海洋行星是一种类地行星，不过它们的表面完全被液体所覆盖，通常液体种类是我们熟知的水。尽管液态的星球表面非常的平滑，但是下层的固体洋底却有显著的地貌变化和差异。正也是这种次表面的不规则性导致了复杂气候系统的形成，否则其气候特征将会较为单一。

Oceanic worlds are a class of terrestrial world covered entirely by liquids, usually in the form of mundane water. While the liquid surface is exceptionally smooth, the ocean floor on most worlds of this type exhibits significant topographic variety. It is this subsurface irregularity which causes the formation of complex weather systems, which would otherwise revert to more uniform patterns.
