Position 1: Improved detection through satellite-based sensors and numerical weather models has therefore become a priority for communities in vulnerable coastal regions.

Position 2: Although they occupy only about ten percent of Earth's circumference at any given time, they account for more than ninety percent of the poleward flux of water vapour.

Position 3: Such events can deliver beneficial rainfall that replenishes reservoirs, yet they can equally cause catastrophic flooding and landslides within days.

Position 4: Atmospheric rivers are narrow corridors of concentrated water vapour that transport moisture from the tropics toward higher latitudes.

Position 5: When these corridors make landfall against mountain ranges, orographic lifting forces the moist air upward, triggering intense and prolonged precipitation.
