Pic-o-the-Day: Thunderstorm threatens Goldie
(not the 'Pic-of-theDay' selection - but certainly merits it)
Picture of the Day
'Thunderstorm threatens the Gold Coast'
Surfersvillage Global Surf News, 5 November, 2012 : - - Our 'Pic of the Day' choice, 'Thunderstorm threatens the Gold Coast', was sparked by recent storm photographs of Hurricane Sandy. The Bureau of Meterology's 2013 Calendar presents 'nature's sky show' featuring 13 amazing photos photographs.
The Calendar's theme is 'Data from the Void' and Ann's photo (below) was selected for the month of October, coincidently the same month, but not same year, as Hurricane Sandy.
The weather calendar is produced each year by the bureau and the Australian Meteorological and Oceanographic Society. It is the bureau's most popular publication. The Bureau gathers essential information from 'data sparse regions' above and below the southern hemisphere oceans.
Conventional sources such as manned island stations, ship reports and satellite data are now complemented by global fleets of robot underwater floats, moored and drifting weather buoys and other high-tech devices.
Thunderstorm threatens the Gold Coast, Qld : photo Ann Van Breemen / courtesy BOM
3pm, 29 November, 2008: Ann Van Breemen was at her computer, 33 floors above Queensland's Gold Coast, when she chanced to turn and look out the window of her apartment. Things happened fast. 'Massive cloud going past the window', she recalls. 'I only had time for a couple of shots as it went past so quickly'.
Ann's photograph shows shelf clouds (arcus) formed by the thunderstorm's outflow. They are best described as low, horizontal wedgeshaped clouds attached to the base of the parent cloud. On this day thunderstorms were triggered by a low pressure trough crossing eastern New South Wales and southern Queensland.
Ann agrees with the Boy Scout motto: 'Always be prepared.' and adds a tip: 'Always look behind you ... I was once set up on a beach, shooting the sunrise, when I realised the best shot was of the highlighted clouds behind me.'
The calendar is available from Tuesday 6 November online here and at Bureau of Meteorology offices.
