BBC’s weather forecast is a _______ program.

In Britain, just as the largest audience is watching the main television news programs, it’s weather forecast time. The BBC broadcast 44 live forecasts a day, 433 hours of weather a year, using forecasters from the Meteorological Office. The Met Office makes predictions about the weather 7 days in advance. These are based on observations from the ground, from satellites and from radar.
    The observations are stored in computers that can do up to 4 billion calculations per second. In Britain, the weather is news. A television weather forecast often begins with an interesting fact: The town with the top temperature of the day or the place with the most rain. "The public like that kind of information," says senior forecaster Bill Jails, "The BBC forecasters are professional meteorologists, but they don’t have an easy job." They are the only presenters on television who do not use a script and they cannot see the map that they are describing. Viewers are often critical, especially of female presenters. One woman left the job after rude letters and press reports about her clothes.
    The British talk about the weather more than any other subject, so it is surprising to discover 70% of television viewers cannot remember what they saw on the weather forecast. "What happens", says one forecaster, "is that people like watching and hearing the forecasters, but they probably only take real notice when they need to, or of course, when we make mistakes."
