PlanetaryWaves: A 4D Physics-Based Model for Winds-Driven Waves on Alien Oceans

To the point

PlanetaryWaves is a physics-based model that predicts how winds generate waves on alien oceans by integrating gravity, atmospheric conditions, and liquid properties to yield a four-dimensional map of surface elevations that works for any planet, and after validating it with two decades of Lake Superior buoy data it was used to study Titan, Mars, and exoplanets, showing that mild winds could raise about three-meter waves on Titan’s methane‑ethane lakes, that Mars would need stronger winds as its atmosphere thinned, and that higher gravity or more viscous liquids suppress waves on worlds such as LHS 1140 b, Kepler‑1649b, and 55 Cancri e, in a project led by Andrew Ashton of the Woods Hole Oceanographic Institution with implications for future Titan missions and insights into planetary surface evolution, while noting the predictions rely on assumptions that require future measurements to test them.
