Sydney Weather Forecast And Warnings Always Available At Bureau Of Meteorology Website
The originating source for the Sydney weather forecast is the Australian Bureau of Meteorology, referred to locally as the BOM. Media outlets rely on BOM forecasts. Details provided by TV, radio, newspapers and the Internet sources are based work by the BOM.
The BOM provides special services for mariners. The BOM passes on its information to several maritime agencies. These authorities broadcast it via marine radio. There are three distinct Australian marine radio networks, namely, the Coast Radio Network, the network operated by the Australia Maritime Safety Authority and, finally, the Volunteer Coastal Stations. All three services relay BOM weather reports, both warnings and forecasts.
AMSA provides high frequency (HF) radio transmissions. It programs automated transmissions of BOM weather reports for the open ocean (offshore areas) as well as coast areas. AMSA stations simultaneously broadcast voice and radio-fax weather reports. Marine warnings are broadcast every hour on the hour. Weather forecasts are broadcast on a fixed schedule and repeated every four hours. The two stations use six frequencies for voice radio transmissions and five frequencies for radio-fax transmissions. Lower frequencies are used at night and the higher frequencies at day.
The far left of the home page provides a list of services presented on the BOM website. These include not only weather services but also climate services, water information services, water and the land (agricultural services), ocean services, marine services, aviation services, a tsunami warning services, registered user services and commercial services for which a fee is charged. There is some overlap in the detailed information provided under each of these tabs. For example, the water information services tab and the water and the land (agricultural services) tabs each provide, in some instances, links to the same data items.
The AMSA radio network consists of two radio stations, one at Charleville (Queensland) and the other at Wiluna (Western Australia). These two remote, inland towns may seem absurd locations at which to locate bases for marine radio transmissions, however they are considered electronically quiet with an absence of interference that is geographically rare. The respective call signs for services from these stations are VMC Australia Weather East for Charleville and VMW Australia Weather West for Wiluna.
The middle right section provides links to full weather information for each state and territory, radar images, satellite images and a comprehensive range of synoptic charts (including charts for mean sea level pressure, UV index, short term forecast and a 4-day forecast). This section of the home page also contains links to a monthly feature article, a new graphical forecast service and special service announcements issued from time to time by the BOM.
The CRN stations may, on an optional basis, monitor for distress calls on VHF channel 16. They may also, again on an optional basis, transmit local weather broadcasts on channels 16 and 67. Radio broadcasts using very high frequency (VHF) signals are accessible by mariners positioned on inshore waters, that is, within relatively short distances from the point of transmission. VHF broadcasts are not designed to reach mariners on the high seas.
Naturally, a Sydney weather forecast is available 24x7 to anyone anywhere in the world provided they have an Internet connection and can access the BOM website. The forecast is routinely revised with updated information at least twice per day.
