| | 25 | This sequence shows the development of cumulus clouds at an accelerated pace in the homogeneously-heated convective boundary layer. The shown time period spans approx. 80 minutes, the shown region is of size 1.4 km x 1.4 km in the horizonzal and 1.5 km in the vertical direction. The clouds are represented through the liquid water content. Darker (gray) shades refer to a higher water content than white shades. The background scenary here is not physical and used for decorational reasons only. |

| | 64 | As sequence one, but a different cloud at a different location. The shown region is of size 1.0 km x 1.2 km in the horizonzal and 1.5 km in the vertical direction. The arrows indicate the strength and direction of the wind in a vertical plane through the center of the cloud. Red and blue colors refer for up- and downdrafts, respectively. |
