Inertial wave lakes, and laboratory experiments. Rossby waves, geostrophic currents, and geostrophic winds are examples of inertial waves. Inertial waves are also likely to exist in the molten core of the rotating Earth. Inertial waves are restored to equilibrium by the Coriolis force, a result of rotation. To be precise, the Coriolis force arises (along with the centrifugal force) in a rotating frame to account for the fact that such a frame is always accelerating. Inertial waves, therefore, cannot exist without rotation. More complicated than tension on a string, the Coriolis force acts at a 90° angle to the direction of motion,
The Winds of Winter the "Game of Thrones" season four premiere, Martin posted a chapter on his website, titled "Mercy". Martin said the new chapter is actually an old one, though never published nor publicly read. In April 2015, Martin posted a Sansa Stark viewpoint chapter from "The Winds of Winter" titled "Alayne".
