| Highly nonlinear models can convect vigorously for an interval of time and then stop, allowing the system to revert to a stable form. |
| If the magnetospheric electric field remained steady, the particles drifting around the Earth would lose their energy on the dayside and convect to the magnetopause, where they would be lost to the solar wind. |
| The water above the springs does not convect when it is cold. |
| Apparently, the interiors of the Moon, Mercury, and Mars are either too rigid or have lost too much of their internal heat to convect and drive plate tectonics. |
| A small grille just above the keyboard serves as an exit for the heat-pipe used to convect heat away from the processor. |
| Who of us has dared venture close enough to feel the air convect in our ears? |
