Task：The process of Australian Bureau of Meteorology collecting up-to-the-minute information on the weather in order to produce reliable forecasts.
1. 需要看懂图形之间的顺序，并找到流程的起点和终点。如：Incoming Information→Analysis Forecasting→Preparing The broadcast→Broadcast)
5. 为了突出顺序性，需要采用大量的连接词进行辅助说明，如At first, Secondly, then, next, after that, finally等。
The flowing chart illustrates the process which is used to collect up-to-the-minute information on the weather by the Australian Bureau of Meteorology.
4 sequential stages should be required for forecast broadcasting, including information collecting, analysis and forecasting, computer-based preparing and broadcasting to the public.
Firstly, there is an all-around monitoring system based on 3 types of incoming information receivers, namelysatellite in space, Radar on land and Drifting buoy in ocean, all of which ensure a high-level integrity of data sources, geographically.
In phase two, for the purpose of analysis and forecasting, the original data is converted into visible patterns. Specifically, visual satellite photos can be obtained, figures can also be presented in radar screen, and synoptic charts can be drawn by the cooperation of radars and drifting buoys.
The next stage involves computer, which serves to make the preparation for broadcasting by synthesizing and processing the graphic information mentioned above.
At last, weather-forecast results are delivered into the public through different media, from Television to Radio to recorded telephone announcement.
