Work trends of Shandong Meteorological Bureau

"The development of marine meteorological services closely following the needs of the' blue economy' is the main theme of the development of meteorological undertakings in Shandong at present and even for quite a while!" 20 10 China meteorological bureau incorporated Shandong meteorological bureau into the pilot work unit of marine meteorological forecast of China meteorological bureau. After three years of hard work, Shandong meteorologists handed in a heavy answer sheet for the pilot work: the marine meteorological technical system and intensive business process were initially established; Standardized and intensive marine meteorological fine forecasting business model has basically taken shape; The professional marine forecasting team is becoming more and more mature; The support capacity of marine meteorological science and technology has been significantly enhanced; The accuracy and refinement level of marine weather forecast have been significantly improved, and the service ability has been significantly improved ... Climb high and look far, closely follow the top-level design requirements, and start from the foundation of soil. Facing the new demand, it is particularly critical to revise and innovate the top-level design of marine meteorological forecasting business. "In view of the new demand, according to the coastal areas, the meteorological conditions in coastal areas and the current situation of marine transportation production, the sea areas will be re-divided to ensure the pertinence and effectiveness of marine meteorological services." Li Zhenhai, director of forecasting department of Shandong Meteorological Bureau, said. At present, Shandong Meteorological Bureau has divided the fine sea area of the responsible sea area into five coastal waters according to China Meteorological Bureau's Regulations on Marine Meteorological Forecast (Trial), weather and climate characteristics and common geographical divisions, combined with the reality of coastal and coastal waters. Among them, the service demand of the southern Bohai Sea involves various marine economic activities such as offshore oil production, marine fishery and marine aquaculture. The coastal waters within 10 km of Shandong coastline are subdivided into 12 coastal waters, and the marine meteorological services are mainly for ports, mariculture, marine salt industry, marine engineering construction and other industries. The reporter learned that the division of marine meteorological service sea areas in Shandong also involves sea routes in the province. At the Shandong Ocean Meteorological Observatory, the reporter saw that four important routes, including Yantai-Dalian, Penglai-Lushun and Weihai-Dalian, were all in the responsible sea area of Shandong. The rational division of labor and intensive development of marine meteorological services in Shandong Province is a highlight in the pilot project of marine meteorological forecasting services in Shandong Province. Li, deputy director of the Shandong Meteorological Bureau, said that in the top-level design, the Shandong Meteorological Bureau highlighted the optimization of the post setting of marine meteorological services at the provincial, city and county levels, improved the post responsibilities and the construction of marine meteorological forecasting teams, and took it as a "troika" to drive the overall situation. In 2009, Shandong Meteorological Observatory established the Ocean Forecasting Department, with a staff of six. In the same year, the meteorological departments of seven coastal cities in Shandong Province all became municipal marine meteorological stations. Qingdao and Yantai shall set up full-time marine forecasters, and the marine meteorological services of Rizhao, Weifang, Weihai, Binzhou and Dongying shall be undertaken by the Municipal Meteorological Observatory, with 2 professional posts of marine meteorological forecasting1-. Counties (coastal areas) highlight the principle of integration of forecasting service posts and effectively carry out marine meteorological forecasting and early warning services. At the same time of the construction of marine meteorological forecasting business institutions in provinces, cities and counties, Shandong meteorological department further clarified the responsibilities of the three-level marine meteorological service, and combined with the fine division of the responsible sea areas, made the three-level meteorological departments perform their duties and responsibilities, ensuring the smooth development of marine meteorological forecasting services. Intensive standardization, innovative forecasting process products "standardized business processes can improve service efficiency, and rich forecasting products can improve service effect." In the process of exploring marine meteorological forecasting business, Shandong meteorological department has formed an interactive forecasting business process by relying on collective wisdom, which organically combines national and provincial technological advantages with prefecture-level experience. Li Zhenhai introduced that the forecast products of the National Meteorological Center were directly applied to the forecast of five offshore waters. 12 is responsible for further standardizing the process of coastal sea area and route forecast in the province. For example, the forecast of five coastal areas is made by the Provincial Marine Meteorological Observatory, and the products are transmitted to the marine meteorological forecast business platform of Shandong Province to realize the enjoyment in the province. Service companies can call forecast products for direct external services. 12 coastal area forecast adopts the principle of provincial guidance, municipal revision and unified release. On the other hand, give full play to the advantages of marine meteorological forecasting in coastal cities of Yantai and Weihai, and Yantai Meteorological Observatory will take the lead in guiding and forecasting the route forecast in the whole province, and upload the revised forecast products to the provincial marine meteorological forecasting business platform to realize the enjoyment of the whole province. The reporter learned that the meteorological department in Shandong has also strengthened the weather forecast and early warning of marine disasters. When it is predicted that there will be a gale of magnitude 6 or above in the responsible sea area within 24 hours, a gale yellow warning signal will be issued when there will be a gale of magnitude 8 or above in the responsible sea area within 12 hours, a gale orange warning signal will be issued above 10, and a gale red warning signal will be issued above 12 hours; Forecast that there will be sea fog with visibility less than 1km in the sea area, and release the sea fog forecast; When a large area of sea fog is detected, refer to the rules for issuing inland fog warning information, and issue sea fog warning signals as appropriate. The reporter learned from the Disaster Reduction Department of Shandong Meteorological Bureau that at present, the refined marine meteorological forecast in Shandong Province has been officially served to the outside world. When issuing gale warning, gale warning signal, typhoon warning signal and sea fog warning signal, make important weather forecast and send it to relevant decision-making departments such as provincial party committee, provincial government, provincial safety supervision bureau, maritime safety administration and maritime search and rescue center to carry out decision-making services; Detailed forecasts of five coastal areas and 12 coastal areas are published twice a day through websites, provincial satellite TV stations and provincial radio stations; The refined navigation forecast is mainly provided by coastal meteorological stations through media and websites, and early warning or early warning signals are issued through Shidao voice broadcasting station, covering a radius of 500 kilometers; The refined sea area forecast and route forecast are reprocessed to provide professional marine meteorological services for shipping companies, ocean-going companies and terminals. Combine vertically and horizontally, strengthen the support of service science and technology, join hands with strong forces, share resources, and benefit both sides. The pilot work of marine meteorological service in Shandong meteorological department has embarked on a new path of business modernization. Li Zhenhai said that in recent years, the Shandong Meteorological Bureau has actively cooperated with universities, and the provinces and cities have cooperated to tackle key problems in marine meteorological science and technology, and the supporting capacity of marine meteorological science and technology has been continuously improved. Since 2009, Shandong Marine Meteorological Observatory has researched and established the satellite automatic identification system of sea fog in the Yellow Sea and Bohai Sea at night based on MTSAT satellite, which has realized 24-hour continuous monitoring of sea fog, and related monitoring products have been applied in the whole province. At the same time, the Shandong Provincial Marine Meteorological Observatory has initially established a database of historical sea fog cases in the Yellow Sea and Bohai Sea, and the level of sea fog forecast has been improved. Only 20 1 1 year, the sea fog forecast 126 times was issued, and good service effect was achieved. The Shandong Ocean Meteorological Observatory and Yantai Ocean Meteorological Observatory carried out a comparative observation experiment of sea surface wind field, which solved the availability problem of wind measurement at each station under the influence of complex topography in the Bohai Strait, clarified the error law and correction method of more than 20 island stations under different wind directions, and obtained the "standard" wind field with the height of 10m for real-time operation, providing possible reference for gale forecast in offshore waters. In recent years, Shandong Marine Meteorological Observatory has made a breakthrough in the study of cold current snowstorm, which provides technical support for improving the forecast accuracy. The database of gale cases in Shandong in recent ten years is established, and the gale processes are classified according to the ground flow field, and the forecast indexes are summarized. The forecast model of gale level under different conditions and the objective forecast system of refined sea wind are improved, and the refined level and accuracy of sea gale forecast are improved. Meanwhile, in cooperation with China Ocean University, the meteorological department of Shandong Province has successively introduced and established numerical forecasting systems for sea fog, storm surge and ocean waves, and improved them, which has provided support for meeting the needs of marine professional services. Strive for Excellence and build a first-class business platform. The construction of Shandong marine comprehensive meteorological observation network ranks in the forefront of the country in terms of quantity and types. Relying on the marine meteorological service platform, Shandong has built 224 automatic weather stations, 27 island automatic weather stations, 23 ship automatic weather stations 15, 23 coastal and island anemometers, 4 offshore oil platform stations, 48 coastal and island visibility observation stations, 3 coastal Doppler weather radars and 7 coastal emergency mobile weather stations ... The three-dimensional integrated marine meteorological observation system has basically been completed. Shandong Meteorological Observatory and Yantai Meteorological Observatory have also established the "Dynamic Display and Video Monitoring System for Ships in the Bohai Strait", which can realize the dynamic tracking, classification and identification of ships over 500 tons passing through the Bohai Strait, and monitor the ro-ro ship operation and its surrounding sea and sky conditions around the clock. In addition, Shandong has also established a new generation of polar-orbiting satellites FY-3A and EOS/MODIS receiving and processing systems, providing satellite remote sensing data such as sea temperature, sea fog and sea ice with a resolution of 250 meters. Among them, "Shandong Marine Meteorological Business Platform" integrates the functions of real-time monitoring of marine disastrous weather, early warning, forecasting production, product sharing, weather joint defense, use of forecasting tools, dynamic display of marine ships and video monitoring, and realizes information sharing, interaction between superiors and subordinates, monitoring and early warning and service information database management at provincial, city and county levels, providing technical support for the development of refined forecasting business and marine disastrous weather monitoring joint defense. Sailing at sea, if you don't advance, you will retreat. Shandong meteorologists have raised their sails and are full of confidence and hope for marine meteorological services!
