Mountain Weather

Cloud seeding can modestly influence suitable clouds, but it cannot create rain from clear skies or end drought. Learn what evidence shows.

How do avalanches form when snow layers fail under stress? Explore the mechanics of slab failure and mountain weather triggers to stay safe.

How do snowflakes form from water vapour in the atmosphere? Explore the physics of hexagonal symmetry and the nucleation process in cold clouds.

How does frost form? Learn how water vapour changes to ice through deposition and radiative cooling on clear nights. See why ground frost appears.

Valley fog formation occurs when radiative cooling and drainage flow trap moist air in low terrain overnight. Understand how temperature inversions work.

Learn how upslope fog formation occurs through orographic lifting and adiabatic cooling on Australian mountain slopes.

Learn how Kelvin–Helmholtz clouds Australia form from wind shear and see why these breaking wave patterns appear on layered cloud decks.

Learn how do lenticular clouds form through orographic lifting and mountain waves in stable moist air.

Visit these top Australian cloudspotting hotspots to see Morning Glory and lenticular clouds.

Learn how orographic cumulus clouds form over Australian ranges through topographic lifting and adiabatic cooling. Watch how terrain shapes weather.

Learn how orographic stratocumulus clouds Australia form over mountain ranges and affect local visibility. Explore how terrain shapes weather and Discover.

Learn how orographic stratus forms when moist air lifts over the Great Dividing Range. See why this low cloud affects aviation and visibility.
