The continuous rainy precipitation process from February to March in 2019 was selected to analyze the effect of meteorological service in Tangpu Reservoir basin,so as to sum up service experience and then lay a better foundation for subsequent services.In response to the rainy weather from December 2018 to early 2019,three rounds of flood discharge were carried out in Tangpu Reservoir.During February-March in 2019,the hit rate of short-term area rainfall forecast for Tangpu Reservoir was 80.0%.Compared with the median of forecast interval,the average absolute error was 7.6 mm,and the relative error was 32.7%.The large deviation in the forecast from March 27 to 28 was deeply analyzed,and it is found that the main reasons were excessive reliance on and trust in a single model,insufficient correction of the actual situation,and insufficient judgment of the nature of precipitation.For the future reservoir meteorological service,three aspects of thinking were put forward,such as further strengthening the sharing of hydrological and meteorological information,improving the forecasting ability,and deepening the research of runoff forecast models. 展开更多

By 2018, China had conducted 34 scientific explorations in Antarctica spearheaded by the Chinese National Antarctic Research Expedition(CHINARE). Since the first CHINARE over 30 years ago, considerable work has been undertaken to promote the development of techniques for the observation of surface and upper-air meteorological elements, and satellite image and data reception systems at Chinese Antarctic stations and onboard Chinese icebreakers have played critical roles in this endeavor. The upgrade of in situ and remote sensing measurement methods and the improvement of weather forecasting skill have enabled forecasters to achieve reliable on-site weather forecasting for the CHINARE. Nowadays, the routing of icebreakers, navigation of aircraft, and activities at Chinese Antarctic stations all benefit from the accurate weather forecasting service. In this paper, a review of the conventional meteorological measurement and operational weather forecasting services of the CHINARE is presented. 展开更多

In order to find out the climate change law for Yuxian's tobaccos, and provide a theoretical basis for the rational use of climate resources in.the growing area, the meteorological element variation affecting tobacco growth was analyzed by using unary linear regression equation and other statistical analysis methods based on the observation data of Yuxian Weather Station during 1967-2013. The results showed that the average temperature during the growing period of tobacco in the 47 years period was in the normal growth range of tobacco, close to the lowest value of the optimum temperature. Since 1990, there were only 2 years having the accumulated temperature of days with ≥10 ℃ accumulated temperature less than the required accumulated temperature (2 600 ℃.d ) for tobacco growth. The aver- age of frost-free days of flue-cured tobacco in Yuxian in 47 years was 18.7 d more than the required days for the normal growth and maturation of tobaccos. The av- erage of precipitation during the growing period over the years was much lower than the required value for the normal growth of tobaccos. The sunshine hours for Yuxian's flue-cured tobacco in the field could meet the requirements for growing high-quality tobaccos. The sunshine hours in harvest and curing period were a bit more than the required number for growing high quality tobaccos. It was cold in winter and spring in Yuxian, during which the dry climate was not conducive to the occurrence of pests and diseases. However, with the warming climate, the pest dis- eases occurred easily. In order to avoid or mitigate meteorological disasters, it was necessary to rationally select the types and planting areas of tobacco, timely carry out irrigation and artificial rain enhancement and hail suppression, and establish a rational meteorological service system as well as early conduct prediction, notifica- tion and prevention of tobacco disasters. 展开更多

Based on the survey data of public meteorological services,differences between users' needs for public meteorological services were analyzed by using Maslow's hierarchy of needs and the principle of information availability in behavioral economics. The results show that users' needs for meteorological services follow certain laws,and the public's needs for meteorological information are driven by physiological needs firstly and then by safety needs,while they are driven by upper needs finally. Meanwhile,users' needs for meteorological services have particularity.Under special backgrounds,there are certain differences between users' needs and laws of basic needs,and users' needs are inconsistent with the " ideal needs" of meteorological departments. Studying the laws and particularity of differences between users' needs for meteorological services in detail is conducive to a survey of the public's needs for meteorological services and improvement of meteorological service quality. 展开更多

To study the temporal and spatial changes of heat resources to serve agricultural production and economic development. The climate data from 1958 to 2017 were selected, and the temporal and spatial changes of heat resources in Liaoning, China were analyzed by using the method of climate diagnosis and analysis. The results show that: the southern coastal area of Liaoning has the most heat resources, the northwestern hilly area and the eastern mountainous area the least, and the central plain area in the middle distribution pattern;compared with 1958-1980, 1981-2017 ≥0&#176;C, ≥10&#176;C accumulated temperature, etc. The value line is advanced 100-160km northward. The accumulated temperature of ≥0&#176;C and ≥10&#176;C in Liaoning experienced abrupt changes in climate in 1993 and 1994, and the climate abrupt change in the southern coastal area was earlier than that in the inland. , the increase in the northwestern hilly area and the eastern mountainous area is less than that in the central plain area and the southern coastal area. The study on the impact on meteorological services found that the increase or decrease of heat resources has a significant impact on agro-meteorological services, which can prolong the growing season of crops, relatively reduce the damage of frost, improve comprehensive utilization of land, and increase crop yields;at the same time, with the increase of heat resources and the northward expansion of the isoline of accumulated temperature, the area affected by pests and diseases has expanded, which has aggravated the harm to agriculture economic burden. 展开更多

Based on service-oriented architecture(SOA),a Bellman-dynamic-programming-based approach of service recovery decision-making is proposed to make valid recovery decisions.Both the attribute and the process of services in the controllable distributed information system are analyzed as the preparatory work.Using the idea of service composition as a reference,the approach translates the recovery decision-making into a planning problem regarding artificial intelligence (AI) through two steps.The first is the self-organization based on a logical view of the network,and the second is the definition of evaluation standards.Applying Bellman dynamic programming to solve the planning problem,the approach offers timely emergency response and optimal recovery source selection,meeting multiple QoS (quality of service)requirements.Experimental results demonstrate the rationality and optimality of the approach,and the theoretical analysis of its computational complexity and the comparison with conventional methods exhibit its high efficiency. 展开更多

Floods often cause significant crop loss in the United States. Timely and objective information on flood-related crop loss, such as flooded acreage and degree of crop damage, is very important for crop monitoring and risk management in ag- ricultural and disaster-related decision-making at many concerned agencies. Currently concerned agencies mostly rely on field surveys to obtain crop loss information and compensate farmers' loss claim. Such methods are expensive, labor intensive, and time consumptive, especially for a large flood that affects a large geographic area. The results from such methods suffer from inaccuracy, subjectiveness, untimeliness, and lack of reproducibility. Recent studies have demonstrated that Earth observation (EO) data could be used in post-flood crop loss assessment for a large geographic area objectively, timely, accurately, and cost effectively. However, there is no operational decision support system, which employs such EO-based data and algorithms for operational flood-related crop decision-making. This paper describes the development of an EO-based flood crop loss assessment cyber-service system, RF-CLASS, for supporting flood-related crop statistics and insurance decision-making. Based on the service-orientated architecture, RF-CLASS has been implemented with open interoperability specifications to facilitate the interoperability with EO data systems, particularly the National Aeronautics and Space Administration (NASA) Earth Observing System Data and Information System (EOSDIS), for automatically fetching the input data from the data systems. Validated EO algorithms have been implemented as web services in the system to operationally produce a set of flood-related products from EO data, such as flood frequency, flooded acreage, and degree of crop damage, for supporting decision-making in flood statistics and flood crop insurance policy. The system leverages recent advances in the remote sensing-based flood monitoring and assessment, the near-real-time availability of EO data, the service-oriented architecture, geospatial interoperability standards, and the standard-based geospatial web service technology. The prototypical system has automatically generated the flood crop loss products and demonstrated the feasibility of using such products to improve the agricultural decision-making. Evaluation of system by the end-user agencies indicates that significant improvement on flood-related crop decision-making has been achieved with the system. 展开更多
