During recent storms, satellites recorded ocean waves averaging nearly 20 meters high—as tall as the Arc de Triomphe in Paris and the largest ever measured from space. Moreover, satellite data now reveal that ocean swells act as storm “messengers”: even though a storm may never make landfall, its swell can travel vast distances and bring destructive energy to distant coastlines.
