A dramatic photo of a lightning storm competing with this year's Australia Day fireworks in Perth has been chosen as the January image in the Weather Bureau's 2013 Australian Weather Calendar.
Perth science teacher Matthew Titmanis endured pouring rain to take the photo and said he knew he had captured something amazing by the crowd reaction when the lightning struck.
"The comparison between the man-made fireworks and nature's lightning strike, which was more spectacular, was amazing," Mr Titmanis said.
The theme for the 2013 edition, Data from the Void, focuses on how the bureau gathers information from southern hemisphere oceans and features 13 photographs from across the country.
"From an Australia Day lightning display that competes with fireworks in Perth, to rows of deep pink and violet stratocumulus clouds in country Victoria, or clouds casting dappled shadows on the terracotta-coloured Simpson Desert - this calendar presents an enduring record of the moments when nature puts on her most dramatic show," the bureau's calendar project manager Robert Kershaw said.
The not-for-profit calendars can be bought at the bureau's office in West Perth, other regional offices throughout Australia or online at http://shop.bom.gov.au.
