Cloud inversion - the condition that inspired Inverza's name - creates a sea of clouds filling valleys while mountain ridges rise above like islands. It happens when cold, humid air pools in valleys overnight under a temperature inversion: the air at lower elevations is colder and more humid than the air above, trapping moisture in a dense, photogenic layer.
The detector evaluates humidity (85%+), calm winds (below 5 km/h), and temperature inversion strength between valley floor and ridge. A stronger inversion means the cloud layer stays more distinct and photogenic.
