- Clouds can foretell the weather: large-scale lift or cooling aloft
- W033666Z
- Clouds can foretell the weather. The only way to get a sky like this, filled with dark bases crammed together, is when large-scale lift or cooling aloft spreads in overhead. This causes the atmosphere to destabilize uniformly over a wide area, allowing all the Cumulus clouds to grow taller. This situation will change when a few favored cells evolve into storms, decreasing other clouds nearby.
