The CP2 Research radar was a 1970's era radar, which the BoM received as a gift from the NCAR in the United States. The BoM retrofitted it with modern parts which gave it the unique ability to collect data at two frequencies, S and X band. The upgrades also provided state of the art dual polarisation and doppler technologies.
The Bureau of Meteorology is the main provider of weather forecasts, warnings and observations to the Australian public. 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 ...
The Citizen Weather Observer Program is a program to collect surface weather observations from thousands of privately operated weather stations, into the FindU database, and forward it to the Meteorological Assimilation Data Ingest System (MADIS Archived 2009-03-12 at the Wayback Machine), operated by the National Oceanic and Atmospheric Administration (NOAA).
The 2024–25 Australian region cyclone season is an ongoing weather event in the southern hemisphere. The season has officially started on 1 November 2024 and will end on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total.
The storm was upgraded to a Category 1 tropical cyclone on the Australian scale by the BOM at 18:00 UTC on 11 May, while located approximately 1,420 km (880 mi) east of Cairns. [2] Located just within the Australian region at this time, the newly formed cyclone was named Ann by the BOM.
In October 2020, Australia's Bureau of Meteorology (BOM) issued its tropical cyclone outlook for the 2020–21 season, and in the same month, the agency contributed towards the Southwest Pacific Tropical Cyclone Outlook, along with New Zealand's MetService, NIWA and the Fiji Meteorological Service (FMS).
Not all reanalysis data are constrained by observation: some data types, such as precipitation (depending on the reanalysis) and surface evapotranspiration (for which global observations simply do not exist), are obtained by running (presumably newer) general circulation or NWP models. Reanalyses are known not to conserve moisture.
The first real-time forecasts made by Australia's Bureau of Meteorology in 1969 for portions of the Southern Hemisphere were also based on the single-layer barotropic model. [18] Later models used more complete equations for atmospheric dynamics and thermodynamics. In 1959, Karl-Heinz Hinkelmann produced the first reasonable primitive equation ...
