However water vapour is not pulled away from cloud forming regions when only deep 15 km updraughts are present.

When only the deeper updraughts are present in climate models, more clouds form and there is an increased reflection of sunlight.

When updraughts rise only a few kilometres they reduce total cloud cover because they pull more vapour away from the higher cloud forming regions.

Sometimes updraughts can even cause the falling torrents to be blown upwards.

For example, later stages introduce a constant updraught of wind allowing Link to glide over a bottomless pit whilst an onslaught of fire and bomb arrows sail past him.

Observations show when water vapour is taken up by the atmosphere through evaporation, the updraughts can either rise to 15 km to form clouds that produce heavy rains or rise just a few kilometres before returning to the surface without forming rain clouds.

The dynamics and thermodynamics are fairly well - understood: convection (updraughts) bring moist air up and the water vapour condenses (usually on cloud condensation nuclei, CCN) as the air gets supersaturated — it cools as it ascends and expands (lower pressure).
