McArthur Forest Fire Danger Index
The McArthur Forest Fire Danger Index (FFDI) was developed in the 1960s by CSIRO scientist A. G. McArthur to measure the degree of danger of fire in Australian forests. The index combines a record of dryness, based on rainfall and evaporation, with meteorological variables for wind speed In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature. Wind speed is now commonly measured with an anemometer. Wind spe ..., temperature and humidity. A similar approach was adopted by McArthur for grassland areas. Luke and McArthur details the early development and use of these indices. In 1980 Noble et al. produced algorithms based on mathematical equations of best fit. These algorithms have been used since the early 1980s to enable easy computation. However they are often used with input values outside McArthur's intended design, resulting in FFDI values in excess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Country Fire Authority
The Country Fire Authority (CFA) is a Volunteer fire department, volunteer fire service responsible for fire suppression, rescues, and response to other accidents and hazards across most of the state of Victoria (Australia), Victoria, Australia. CFA comprises over 1,200 brigades organised in 21 districts, and shares responsibility for fire services with Fire Rescue Victoria (FRV), which employs full-time paid firefighters in major urban areas; and Forest Fire Management Victoria (FFMV), which manages fire prevention and suppression on Victoria's public lands. CFA operations and equipment are partly funded by the Victorian Government through its Fire Services Levy, and supplemented by individual brigades' fundraising for vehicles and equipment. CFA was established in 1944 to reform rural fire management in Victoria after a succession of devastating bushfires. Major bushfire responses conducted by CFA have included those in the Dandenong Ranges in 1962 and 1967, the 1965 Gippsland ...

CSIRO
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency that is responsible for scientific research and its commercial and industrial applications. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia as well as in France and the United States, employing over 6,500 people. Federally funded scientific research in Australia began in 1916 with the creation of the Advisory Council of Science and Industry. However, the council struggled due to insufficient funding. In 1926, research efforts were revitalised with the establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly, achieving significant early successes. In 1949, legislative changes led to the renaming of the organisation as Commonwealth Scientific and Industrial Research ...

Wind Speed
In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature. Wind speed is now commonly measured with an anemometer. Wind speed affects weather forecasting, aviation and maritime operations, construction projects, growth and metabolism rates of many plant species, and has countless other implications. Wind direction is usually almost parallel to isobars (and not perpendicular, as one might expect), due to Earth's rotation. Units The meter per second (m/s) is the SI unit for velocity and the unit recommended by the World Meteorological Organization for reporting wind speeds, and used amongst others in weather forecasts in the Nordic countries. Since 2010 the International Civil Aviation Organization (ICAO) also recommends meters per second for reporting wind speed when approaching runways, replacing their former recommendation of using kilometers per hour ( ...

Black Friday (1939)
The Black Friday bushfires of 13 January 1939, in Victoria, Australia, were part of the devastating 1938–1939 bushfire season in Australia, which saw bushfires burning for the whole summer, and ash falling as far away as New Zealand. It was calculated that three-quarters of the State of Victoria was directly or indirectly affected by the disaster, while other Australian states and the Australian Capital Territory were also badly hit by fires and extreme heat. This was the third-deadliest bushfire event in Australian history, only behind the 1983 Ash Wednesday bushfires and the 2009 Black Saturday bushfires. Fires burned almost of land in Victoria, where 71 people were killed, and several towns were entirely obliterated. Over 1,300 homes and 69 sawmills were burned, and 3,700 buildings were destroyed or damaged. In response, the Victorian state government convened a Royal Commission that resulted in major changes in forest management. The Royal Commission noted that "it appe ...

Black Saturday Bushfires
The Black Saturday bushfires were a series of bushfires that either ignited or were already burning across the Australian state of Victoria. Saturday, 7 February 2009 was one of Australia's all-time worst bushfire disasters. The fires occurred during extreme bushfire weather conditions and resulted in Australia's highest-ever loss of human life from a bushfire, with 173 fatalities. Many people were left homeless and family-less as a result. As many as 400 individual fires were recorded on Saturday 7 February; the day has become widely referred to in Australia as Black Saturday. Then Deputy Prime Minister Julia Gillard described Black Saturday as "a tragedy beyond belief, beyond precedent and beyond words … one of the darkest days in Australia’s peacetime history." The 2009 Victorian Bushfires Royal Commission, headed by Justice Bernard Teague, was held in response to the bushfires. Background A week before the fires, a significant heatwave affected southeastern Aus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bushfires In Australia
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. However, the fires can cause significant property damage and loss of both human and animal life. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals. The most destructive fires are usually preceded by extreme high temperatures, low relative humidity and strong winds, which combine to create ideal conditions for the rapid spread of fire. Severe fire storms are often named according to the day on which they peaked, including the five most deadly blazes: Black Saturday bushfires, Black Saturday 2009 in Victoria (Australia), Victoria (173 people killed, 2,000 homes lost); Ash Wednesday bushfires, Ash Wednesday 1983 in ...
