Australian Weather Calendar - July 2014
Brooding summer storm bursts into colour
Most of the rain that falls on Mt Isa, Queensland, is from summer thunderstorms, and more than three-quarters falls from December to March. As the land heats, the dominant weather pattern becomes the inland trough, an area of low pressure marking the boundary between warm, moist air and cool, dry air. The instability associated with this low pressure trough generates thunderstorms. That was the situation in 2013, when photographer and Mt Isa resident, Roslyn Budd, watched an afternoon storm brew. By sunset, it developed 'gorgeous colours', so Roslyn raced out with her camera. 'It was a beautiful, beautiful storm. It was really quite spectacular.'
