The diagram illustrates the process by which weather information is collected, analysed, prepared, and finally broadcast to the public through different media.
Overall, the system consists of four main stages: gathering incoming information, analysing and forecasting weather conditions, preparing the forecast, and broadcasting it to the public. Data is collected from three primary sources, namely satellites, radar systems, and drifting buoys, before being processed into weather forecasts.
In the first stage, weather information is obtained from satellites, radar, and drifting buoys located at sea. Satellites provide satellite photographs, while radar systems generate radar screens displaying weather activity. At the same time, drifting buoys collect meteorological data from oceans and seas. These three sources supply raw information for further analysis.
Next, the collected data undergoes analysis and forecasting. Satellite photographs, radar screens, and synoptic charts are examined in order to predict upcoming weather patterns. The information is then transferred to a central computer, where meteorologists prepare the final weather broadcast.
In the final stage, the completed forecast is disseminated to the public through several forms of media. Weather reports are presented by TV newsreaders on television, transmitted via radio broadcasts, and also delivered through recorded telephone announcements. Consequently, the public can access weather forecasts through a variety of communication channels.
