Analysis of the dilemma and management ideas of urban severe convective weather
At present, severe convective weather on the mainland is frequent, and the types are complex and changeable, often accompanied by wind and rain, thunder and lightning, extreme winds, extreme precipitation, tornadoes and other weather types. Severe convective weather may cause a series of problems such as urban waterlogging, traffic paralysis, and power outage, which not only seriously affects the normal operation of the city and the daily life of residents, but also causes heavy casualties and property losses. Therefore, it is particularly important to strengthen the risk management and research of severe convective weather disaster events.
1. The dilemma of urban severe convective weather disasters
Forecasting is difficult. The formation and development of severe convective weather is affected by a variety of factors, and the interaction and feedback mechanism between these factors are not fully understood, which increases the difficulty of forecasting. In addition, severe convective weather also has the characteristics of early occurrence season and late end, which requires forecasters to maintain a high degree of vigilance for a long period of time, update forecast information in a timely manner, and ensure the safety of the public.
The means of monitoring are limited. Although satellites, radars and other technical means have been used to observe severe convective weather, due to the limitation of observation conditions and technical means, the prediction and observation of severe convective weather such as tornadoes and hail still face high difficulties. Satellite observation covers a wide area, but its temporal and spatial resolution cannot meet the needs of accurate monitoring. Radar can provide higher accuracy data, but its coverage is limited and affected by occlusions such as terrain and buildings.
The defense system is inadequate. The suddenness and unpredictability of severe convective weather make it difficult for existing defense systems to respond immediately and flexibly, increasing the risk of disasters and potential losses. This kind of weather can come on suddenly and develop rapidly, leaving it too late for the relevant authorities to prepare and respond precisely.
Messaging challenges. First, the suddenness and unpredictability of severe convective weather require information systems to collect, process, and disseminate relevant information in a short period of time. Secondly, the granularity of the information is also a big challenge. Granular information includes not only information on the type, intensity, and damage to the disaster, but also details such as the specific situation in the affected area, the need for relief supplies, and the distribution. Finally, information sharing and collaboration between government departments is also an important part of information transmission. Effective information communication and collaboration mechanisms can ensure the comprehensiveness and consistency of information and avoid duplication and contradiction.
Lack of public awareness and preparedness. The suddenness and unpredictability of severe convective weather make it difficult for the public to pay attention to and prepare accordingly. The rapid change and locality of this weather also makes it easy for people to overlook its potential dangers. At the same time, the public's awareness of extreme weather is insufficient, and they do not fully understand the risks and hazards that severe convective weather may bring.
Concurrent evolution of multiple hazards. Severe convective weather is often accompanied by the concurrent evolution of multiple disasters, which increases the complexity and difficulty of disaster prevention and mitigation. Heavy rain, high winds, hail, etc. may trigger a series of secondary disasters. For example, short-term heavy rainfall can cause urban waterlogging, and strong winds and heavy rains can also cause landslides and mudslides.
2 Ideas for the management of severe convective weather disasters in cities
City managers and planners must pay enough attention to severe convective weather and build a responsive and flexible defense system to effectively respond to the challenges brought about by it, ensure the safety of life and property of urban residents, and improve the overall resilience and resilience of cities.
1. Strengthen research and forecasting: Improve the accuracy of forecasting. Through in-depth analysis of historical data and multidisciplinary knowledge, this paper explores the causes and evolution of severe convective weather, and strengthens the basic research on the occurrence and development mechanism of severe convective weather. The use of advanced observation equipment and technology to carry out continuous and high-precision monitoring of the atmospheric environment to improve the monitoring accuracy. With the help of high-performance computer technology and big data analysis methods, the massive amount of meteorological data collected is processed and analyzed. Carry out research on the application of multi-model ensemble forecasting, artificial intelligence and other technologies.
2. Optimize the forecast information release system: ensure that the information is conveyed in a timely and accurate manner. Optimize and improve the forecast information release system to ensure the accuracy and immediacy of information transmission. Establish diversified channels for information dissemination to ensure that information can be disseminated quickly and widely. Strengthen the information review mechanism, strictly review all published forecast information to ensure its accuracy and authority, improve the advancement and reliability of information release technology, and improve the efficiency and accuracy of information processing.
3. Build a sound emergency plan and emergency response mechanism: improve the efficiency of disaster response. Formulate detailed emergency plans, clarify the responsibilities and coordination methods of various departments, and respond to different types of severe convective weather disasters. Regularly assess and update emergency plans to ensure their adaptability and effectiveness. In addition, by strengthening the real-time monitoring and early warning of severe convective weather, setting up a professional emergency rescue response team, establishing sufficient material reserves and other emergency response mechanisms, improving the ability of monitoring, response and coordination, realizing information exchange and collaborative work among various departments, improving rescue efficiency and resource utilization, and reducing disaster losses.
4. Enhance the resilience of cities in disaster prevention and mitigation: reduce potential losses. In terms of urban planning, in-depth research and analysis of the city's topography, climate and other conditions, comprehensive consideration of geological conditions, drainage, wind direction and wind speed and other factors, and actively promote the development of green buildings and ecological cities. In terms of infrastructure construction, part of the urban infrastructure and municipal facilities will be incorporated into the urban underground space. Not only can it avoid direct damage to facilities caused by natural disasters on the ground, but it can also ensure the basic operation of the city in the event of a disaster. In addition, strengthening community management is also an important part of improving the resilience of urban disaster prevention and mitigation.
5. Improve the local microclimate of the city: reduce the probability of disasters. Actively promoting afforestation and increasing urban vegetation coverage can effectively reduce the impact of severe convective weather. High vegetation coverage helps to reduce the absorption of solar radiation on the surface, reduce the surface temperature, reduce the accumulation of energy in the atmosphere, help maintain the stability of the atmosphere, and reduce the probability of severe convective weather from the source. In addition, vegetation can release water through transpiration and increase air humidity, which can help regulate urban temperature, especially in the hot summer, which can effectively alleviate the urban heat island effect.
6. Strengthen the professional training of meteorological personnel: improve the response capacity. Deepen the learning of professional knowledge, and ensure that meteorologists improve their understanding and forecasting ability of extreme weather by regularly organizing them to learn the latest meteorological theories and forecasting techniques. By simulating various extreme weather conditions, meteorological personnel are trained in actual combat to improve their resilience and forecast accuracy in emergency situations. Through strict assessment standards, we ensure that meteorological personnel have excellent professional quality and skills.
7. Raise public awareness of safety: reduce injuries and losses. Through television, radio, the Internet and other media channels, widely publicize the hazards and preventive measures of severe convective weather, so that the public can understand the characteristics of severe convective weather and the risks it may bring. Regularly carry out safety education activities for severe convective weather disasters to improve the public's awareness of prevention and self-rescue and mutual rescue capabilities. Educate the public about safety precautions in severe convective weather.
8. Implement a severe convective weather disaster insurance system to diversify potential economic risks. In the face of the increasingly frequent severe convective weather disasters, it is particularly important to implement an insurance system for severe convective weather disasters. This insurance system can provide economic support to the affected areas, help the victims return to normal life faster, improve the awareness of disaster prevention and mitigation, and reduce the economic losses caused by disasters.
