The diagram below shows how the Australian Bureau of Meteorology collects up-to-the-minute information on the weather in order to produce reliable forecasts.
Sample Response
The ways data are gatheredWays of data gathering, its analysis and weather forecasting, as well as broadcasting methods followed by the Australian Bureau of Meteorology to produce accurate weather forecastsforecast, are illustrated in the process flowchart. As shown in the diagram, the Australian Bureau of Meteorology collects information from different sources, including satelliteslike satellites hovering in space, radar sets positioned at different places on the Earth and drifting buoys at seadrifting buoys anchored to the seabed in the vicinity of the continent. Before forecasting all input data need to be analysedanalyzed, using radar screens and synoptic charts. Satellite and radar information are shown as a satellite photo and a radar screenThe former is designed on the basis of source materials coming from the satellite and radar sets, whereas the latter is compiled on the basis of the information from all sources mentioned above. As soon as the information is analysedAs soon as the information analyzed and the forecast is produceddone, it is prepared for broadcasting. Finally, precisely prepared forecast information reaches TV studios, radio stations and a recorded telephone announcement serviceplaces where it can be recorded for further announcement.
Why this response received Band 6.5
The response gives a generally clear, logically sequenced account of the process, covering the main movement from data collection through analysis to broadcasting and using appropriate process vocabulary. Its main weakness is incomplete visual accuracy, especially the unsupported seabed detail and the unclear role of the computer, so the priority is to follow the diagram precisely while using simpler passive structures to describe each stage.
IELTS Writing Criteria Scores
Task Achievement
The response describes the main process stages from data collection to analysis, forecasting, preparation, and broadcasting. It covers the key inputs and outputs, but it includes a few unsupported details, such as buoys anchored to the seabed, and it does not clearly explain that the computer prepares the broadcast from the three analysis outputs.
Describe only what is shown: satellite, radar, and drifting buoy data are converted into satellite photos, radar screens, and synoptic charts before computer preparation and three broadcast channels.
Coherence and Cohesion
The process is presented in a mostly logical sequence with clear progression from input to output. Cohesion is helped by before, as soon as, and finally, though the opening is heavy and the middle stage could be clearer.
Use a simple overview sentence naming the three broad stages, then describe each stage in order.
Lexical Resource
Vocabulary is generally suitable for a process diagram, with terms such as data gathering, forecasting, broadcasting, radar screens, and synoptic charts. Some phrases are awkward or overcomplicated.
Use concise process language such as data is collected, analysed, prepared, and broadcast.
Grammatical Range and Accuracy
The response uses complex structures, but errors with articles, subject-verb agreement, and passive forms occur. Meaning remains clear overall.
Check passive constructions such as data are analysed and the information is analysed, and use the plural form forecasts where appropriate.
