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

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

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

Based on the previous work on the platforms, we argue that a minimum set of guidelines including workflow scheme, module design, implementation standards and maintenance consideration during the whole establishment of the platform are highly recommended, serving to reduce the need for future maintenance and adjustment. A significant gain in performance can be achieved through the workflow-based projects. We believe that a good workflow system plays an important role in the weather forecast service, providing a useful tool for monitoring the whole process, fixing the errors, repairing a workflow, or redesigning an equivalent workflow pattern with new components.展开更多

A total of 196 risk sites in Guangxi were collected by means of questionnaire survey,expert evaluation and field survey. The results showed that fire,pest and wind hazards are the main types of risk points in Guangxi. The survey showed that there were 77 monitoring stations around the disaster risk sites belonging to the Forestry Sector,which mainly monitor fire hazards,while other disasters had no monitoring point yet. Early warning facilities were still constantly improving. The meteorological disasters that affecting forestry production were drought,gale,and heavy rainfall,and the main meteorological hazard factors were temperature,wind speed,and precipitation. Forest fire prevention,forestry resources development and utilization,forestation and tending demand for meteorological services were relatively large. It was hoped that forestry meteorological service products would be obtained through telephone,SMS and early warning systems. In addition,experts objectivly evaluated the contribution rate of meteorological services in Guangxi. The contribution rate of forest meteorological services in the whole region was8. 41%. The scale of Guangxi's total forestry output value was 31. 478 billion yuan in 2016. According to the calculation of this value,the service benefit value had reached 2. 647 billion yuan. In conclusion,strengthening the cooperation in forestry meteorological monitoring,technology development,and emergency response,and further improving forestry meteorological services and effective reducing forestry disaster losses are the top priorities of the meteorological department.展开更多
