 Listen to the little folk voice.


The Municipal Environmental Protection Bureau was angry by the student in the investigation: can you not release the air pollution early? She hopes that air pollution warning can predict the next 7 days, just like the weather forecast. Shou Ziqi, the director of the Municipal Environmental Protection Bureau, promised her to do her best to move in this direction. This pupils sense of loss can be understood, and the initiative to anger the environmental protection bureau can also be seen as sincere and frank. However, from a realistic and professional point of view, this anger is somewhat naive and exaggerated. It can even be described as excessive criticism. The key to anger lies in the time of air pollution warning. In fact, air pollution early warning is still in a stage of research and development, forecasting and forecasting is also a more complex process. There are multiple factors that need to be taken into account and consideration, and specific judgments and trade-offs also test the experience and level of the forecast professionals. At present, the general method of forecasting 24 hours of air quality can maintain a certain accuracy. It is rare, but it does not exclude many variables and hidden dangers. The air pollution emergency plan for Shanghai (2018 Edition), which was unveiled recently, is only clear that heavy pollution early warning will be released at least one day in advance. This is based on realistic consideration and scientific consideration. It is a scientific and rigorous attitude and a requirement and expectation for accurate prediction of 24 hours. ? As far as the technical conditions are concerned, the prediction of air quality in a longer range can also be achieved, but it is important to realize that the uncertainty of the factors such as pollution sources and specific weather conditions will be increased by the long forecast time. In this way, the change of pollution and the influence of the atmosphere on the diffusion and transmission of pollutants are relatively hard to judge, and the accuracy of the final prediction will also be reduced. Some experts say that excessive and continuous pollution can not be accurately predicted. The prediction of more than 100 hours ahead is very small and even depends on luck. Such a prediction will also greatly reduce its quality and meaning, which is also the objective fact that needs to be recognized. As a result, the pupil s anger and suggestions do not have much substantial significance - of course, we can not be very hard on it. After all, pupils have limited awareness of the principle and mechanism of pollution forecasting. On the contrary, the courage to pay attention to peoples livelihood and dare to speak frankly should be affirmed. However, it also tells us that when we put forward our own demands, we should consider the reality and give consideration to science. On the other hand, objective difficulties still have to be followed by actual efforts. After all, the requirement for early warning of air pollution is the rigid demand of the public. For example, by ramming the technical basis, with the help of large data algorithms and artificial intelligence and other fields, it combines with the weather forecast to research and explore more accurate prediction to meet the public expectations. In addition, the service of the weather forecast can be done more carefully. For example, the starting conditions for early warning are optimized and adjusted to reduce the threshold for early warning of air quality pollution, and then the emergency emission reduction is realized ahead of time and the degree of air pollution is relieved to a greater extent. As a result, although the number of early warning may be more, the workload of the relevant departments should be increased, but the health of the public can be further guaranteed and the effect of service is maximized. In fact, strengthening air pollution warning is also the important content and progress of the new version of the plan. For example, the health tips of special people, such as symptoms of discomfort, medical treatment as soon as possible, the frequency of worksite, road and yard during emergency response, are quantified, and the list of control enterprises and major control measures for the emission of air pollutants in key industries are updated. These refinement and standardization are also the embodiment of striving for precision. It might as well turn the publics harsher into a promise. Facing the problem, we must also see the actual efforts of the environmental protection Forecasting Department. We should pay attention to science and strive for perfection. Normal hope and expectation are the feedback to the Environmental Forecasting Department, and it is also an incentive to help the air pollution early warning, do better, and ultimately achieve the goal of improving the air quality.
