Australian Weather Calendar: July 2015

July photograph by Jordan Cantelo

Isolated heavy rain over the Kennedy Range, Western Australia

Jordan Cantelo captured this image in early 2012. 'When I was flying back along the Kennedy Range some thunderstorms fired up,' he recalls, 'and provided the most magnificent view for us from the helicopter'.

In summer a low pressure trough stretches along Australia's west coast—the boundary between warm, dry, continental air and cooler, moist, sea air from the Indian Ocean. It usually brings fine weather, but as it deepens thunderstorms can form to its east. The pressure chart above shows a trough along the west coast connecting with a heat low—an area of low pressure formed by hot rising air—over the Kimberley.

Jordan took this photo with a Canon 5D Mk II camera and a 24–70 mm lens.
