Why does the weather forecast say it will rain but it will be sunny?
In the interview, Ding, deputy director of Beijing Meteorological Observatory, said: Any new thing has a process of acceptance and digestion. Probabilistic weather forecast is more scientific in form, more objective in forecast results and richer in forecast connotation, so it has more reference value. It is a kind of progress in the development of weather forecast, and there must be a process of acceptance and digestion.
The "precipitation" in the weather forecast is a random event, and the probability of 90% indicates the probability of this random event. We know that in an experiment, there is a 90% probability that the event may not occur, so "it didn't rain yesterday" doesn't mean that there is a 90% probability that the weather forecast for yesterday's precipitation is wrong.
