The roll cloud, or Morning Glory cloud, is a rare phenomenon that looks rather like a horizontal tornado. In reality, it is part of a soliton wave traveling through the atmosphere. At its leading edge, moist air is forced upward, causing water vapor to condense, and, at the trailing edge, air moves downward, dissipating the cloud. These clouds are most frequently observed in Australia near the Gulf of Carpentaria.

Quantum tunneling: a particle tunnels through a barrier that it classically could not surmount. This plays an essential role in several physical phenomena. I like it because the analogous thing happens to internal waves in the ocean.
