The figure illustrates the process used by the Australian Bureau of

Meteorology to forecast the weather.

There are four stages in the process, beginning with the collection of

information about the weather. This information is then analysed, prepared for

presentation, and finally broadcast to the public.

Looking at the first and second stages of the process, there are three ways

of collecting weather data and three ways of analysing it. Firstly, incoming

information can be received by satellite and presented for analysis as a

satellite photo. The same data can also be passed to a radar station and

presented on a radar screen or synoptic chart. Secondly, incoming information

may be collected directly by radar and analysed on a radar screen or synoptic

chart. Finally, drifting buoys also receive data which can be shown on a

synoptic chart.

At the third stage of the process, the weather broadcast is prepared on

computers. Finally, it is delivered to the public on television, on the radio,

or as a recorded telephone announcement.(170)
