Why is the weather forecast in China so forbidden to ask for help from the Great God?

I heard someone complain that when I went out at six or seven in the morning, it was raining heavily outside, but the radio said, "It turns sunny to cloudy during the day." How dare the meteorological station report! The comrades of the Meteorological Observatory said that in fact, in the expression of weather forecast, daytime refers to 8: 00 am to 8: 00 pm, and the Meteorological Observatory did not "falsely report"! This phenomenon is not unique. For example, a thunderstorm was reported somewhere, and afterwards, a citizen went to the station and said, "It just rained a few drops, and your forecast was wrong." But in fact, the appearance of lightning accompanied by formation precipitation is "thunderstorm", and thunderstorm does not necessarily mean rainstorm. Because the public has different understanding of the meaning of different forecasting products, there has been a misunderstanding of "inaccurate forecasting" The accuracy of ordinary people's understanding is often different from that of weather. For example, it is predicted that there will be rain in Xining. When it rains in the north and it doesn't rain in the south, the people are uncertain because the forecast is not detailed in space; In other words, what people think is not "accurate" is actually that the forecast is not "detailed", which is a challenge to the current forecast system and a very realistic problem. It should be said that with the development of social economy and the improvement of people's living standards, governments at all levels and the public have higher requirements for the accuracy and refinement of weather forecast, and their dependence on weather forecast information is also deepening. An unavoidable problem: whether the weather forecast is accurate or not is a relative concept. Weather change is influenced by many factors, and it is a very complex dynamic system. Sometimes the weather forecast is inaccurate, and the reasons are complicated, especially when the climate changes suddenly in summer. Because of the existence of errors, the weather forecast always corrects the errors through continuous rolling forecast. However, once the forecast results provided by the meteorological station are broadcast, they cannot be updated in time. The public generally think that it is the weather situation of the day, which gives the impression that the forecast is inaccurate. On the other hand, most people judge whether the weather forecast is accurate according to their own experience. "It's at least 30 degrees Celsius on such a hot day. How can the meteorological observatory report the highest temperature of 28 degrees Celsius? " In the hot summer, many people have heard such complaints. In fact, the temperature mentioned in the weather forecast refers to the temperature in the louver. The louver is on the lawn, which is 1.5 meters away from the ground, ventilated and not exposed to direct sunlight. But people's somatosensory temperature is influenced by many factors. At the same temperature, there is a great difference between sunny and cloudy, windy and windless, wet and dry, and the difference in feeling can generally reach more than 5 degrees Celsius. A fact that must be faced: the weather forecast cannot be 100% accurate, almost impossible, no matter which country. In fact, refined forecasting is not a new term, and there are many successful cases. People are deeply impressed by the "excellent" performance of refined forecasting in major events such as National Day celebrations and satellite launches. Undoubtedly, in order to achieve the long-term goal of regular, fixed and quantitative daily forecasting, new and higher requirements are put forward for the technical level of forecasting. Let vague terms become less and less, and really report the weather from the needs of citizens' lives. This is the direction to be grasped in future forecasting and the necessity of development.
