The weather forecast only needs the forecaster to broadcast it, right?

The weather forecast announcer is the announcer who sees the weather on the map on TV, and the meteorologist is the staff who measures the data behind the scenes and gets the weather forecast results. So it's not broadcast by the forecaster, but by the weatherman.

Forecasters are the technical support behind the weather forecast. They turn a bunch of incomprehensible data and products into a predictive language that the public can understand. They are on duty 24 hours a day, all year round, and there are no normal holidays and weekends, only shifts.
