The Bureau of Meteorology (BOM or BoM) is an executive agency of the
Australian Government responsible for providing weather services to Australia and surrounding areas. It was established in 1906 under the Meteorology Act, and brought together the
state meteorological services that existed before then. The states officially transferred their weather recording responsibilities to the Bureau of Meteorology on 1 January 1908.
History
The Bureau of Meteorology was established on 1 January 1908 following the passage of the ''Meteorology Act 1906''. Prior to
Federation in 1901, each colony had had its own meteorological service, with all but two colonies also having a subsection devoted to astronomy. In August 1905, federal home affairs minister
Littleton Groom surveyed state governments for their willingness to cede control, finding South Australia and Victoria unwilling. However, at a ministerial conference in April 1906 the state governments agreed to transfer responsibility for meteorology and astronomy to the federal government. Groom rejected a takeover of astronomy due to its connection to universities, which relied on state legislation for their authority.
Henry Ambrose Hunt was appointed as the first Commonwealth Meteorologist in November 1906. Initially the bureau had few staff and issued a single daily forecast for each state, transmitted by Morse code to country areas. Radio forecasts were introduced in 1924. The bureau received additional funding from the late 1930s, in the lead-up to World War II, and it was incorporated into the

(RAAF) from 1941 until after the conclusion of the war. It became an inaugural member of the
World Meteorological Organization (WMO) in 1950. Televised weather forecasts were introduced in 1956.
The 1906 act governing the bureau was repealed and replaced by the ''Meteorology Act 1955'', which brought its functions in line with the expectations of the WMO and allowed for a significant reorganisation of its structure. At this time the bureau came under the

Melbourne, as part of the WMO's World Weather Watch scheme.
In October 2022, the bureau asked media organizations to update their style guides so that they were no longer referred to as "BOM" or the "Weather Bureau". The decision was reversed that week.
Services and structure

The Bureau of Meteorology is the main provider of
weather forecasts, warnings and observations to the Australian public. The bureau distributes weather images via
radiofax and is responsible for issuing
flood alerts
Flood alerts are issued by weather agencies to alert residents that flood conditions are a possibility.

The bureau's head office is in
Melbourne Docklands, which includes the bureau's Research Centre, the Bureau National Operations Centre, the National Climate Centre, the Victorian Regional Forecasting Centre as well as the Hydrology and Satellite sections.
Regional offices are located in each state and territory capital. Each regional office includes a regional forecasting centre and a flood warning centre. The
Adelaide office incorporates the
