* Cumulus clouds form from rising thermals: Cumulus clouds are formed by warm, moist air rising and cooling, causing condensation into water droplets. This process is driven by solar energy heating the Earth's surface.
* Dune's atmosphere is dry: The atmosphere on Arrakis, the setting of Dune, is incredibly dry. This is due to the lack of surface water and the powerful winds that constantly scour the planet.
* Satellites in Dune are primarily for communication: The satellites in Dune are primarily used for communication and weather monitoring, not for manipulating the weather. They are not equipped to generate large-scale changes in atmospheric conditions like the creation of cumulus clouds.
Possible ways satellites *could* influence cloud formation indirectly:
* Dust storms: The powerful dust storms on Arrakis could be influenced by satellite data, helping the Fremen predict and navigate them. Dust storms themselves can contribute to cloud formation, though more likely as large-scale dust veils rather than distinct cumulus clouds.
* Weather forecasting: The satellites could be used to monitor weather patterns and predict changes, potentially giving the Fremen an edge in planning their activities. This could include recognizing when conditions are favorable for natural cloud formation.
Overall, the satellites in Dune are not portrayed as having the capability to directly create cumulus clouds. Their primary purpose is communication and weather monitoring. While they could provide data for indirect influences on cloud formation, creating cumulus clouds on a dry, windy desert planet like Arrakis is beyond their capabilities.
