Learn how do gustnadoes form along thunderstorm outflow boundaries through horizontal wind shear and vertical rotation. Compare them to true tornadoes.

Learn how squall line formation occurs when wind shear and cold pools interact to create destructive linear storms. Discover how these systems work.

Learn how roll cloud formation works when cool air lifts warm moist air along a gust front. Explore the science behind these detached tube clouds.

Shelf cloud formation happens when rain-cooled air lifts warm air along a gust front. Learn how these low arcus clouds mark the edge of a storm.

Identify approaching thunderstorm signs NSW residents can see before a storm hits. Detect cloud growth and wind shifts to stay safe.

Learn how squall lines Australia form and how to identify damaging straight-line winds on radar to stay safe during severe weather.

Learn how multicell thunderstorm clusters form and regenerate via gust fronts. Track storm morphology and severe weather risks across Australia.

Our guide explains the nature of a shelf cloud, how it forms on a gust front, and why it signals a weather change.
