Design And Implementation Of Graphics Display System For Meteorological Data

Because the computer function and the content of today’s weather to explore method of gradually improve, people can know the way and methods of meteorological information more and more, at the same time meteorological information presented in the form of a is becoming more and more varied. With a wide range of meteorological department in our country for meteorological history data informationization, electronic research transformation, China’s meteorological department has been saved in the database since the presence of meteorological data after the record of all kinds of different weather information and meteorological characteristics, such as monitoring data, the monitoring data of high above the ground, and radar monitoring data, and so on. In recent years, the types of meteorological information and the number in the rapid increase, the information on to the single data form to save the meteorological information graphic way need to spend a lot of manpower material resources, and the query process is relatively complex, and cannot satisfy the weatherman more and more intense demand for meteorological forecast and graphical explanation. And we need to know the ground observation and forecasters predicting weather when the most frequently used means of research, so the ground observation is one of the most characteristic and representative meteorological monitoring data information. Of meteorological phenomenon is the ground monitoring information data in the temperature, pressure, humidity, rainfall and wind speed and direction, such as real-time continuous monitoring data of meteorological factors, the content of this article is mainly on the ground test data visualization graphics meteorological station monitoring system of study and exploration, has the profound significance.Based on the meteorological offices and the ground monitoring graphics information service system of B/S mode structure, mainly using the development software, open source ASP.NET WEBGIS technology and graphical representation of data information play an important role of Dundas Chart controls, MICAPS data drawing software such as advanced technology, and combining with the domestic weather stations to save historical meteorological data information, the latest real-time weather information and meteorological data by way of WEB graphical dynamic output targets, further study and its application effect. Then this article is detailed to our design system, system design and system function plate form for the specific design, the architecture of meteorological data information graphics performance means the main technical analysis, after analysis to explore the domestic and international meteorological graphics to the features of the system software and the deficiency, on the basis of Meteoinfo database type characteristic, choose to use C + architectural interface, FORTRAN, the background data processing, GIS geographical data information function and GrADS batch hybrid programming method, complete to flow field, such as color sequence filling, refers to the line and the direction of the wind lever etc. The goals of the graphics display. Development integration can in meteorological station as well as national research department of the successful use of advanced information collection technology, such as three hail figure, TLNP figure, V- 3 theta figure, figure, physical measurement, the wind field trajectory simulation application diagram and fy2 satellite special graphics such as 3 d cloud model, etc.The system in the experimental stage to achieve the history since the ground meteorological observation data and the combination of real-time monitoring information and statistical processing, set up information updated in real time, with the rapid increase of information and data information effectively handle, gradually completed the information accuracy, the standardization, reliability and authenticity of the target. Meteorological data to predict output information more and more diversified, at the same time, the user can in the shortest possible time to design a desired goal, this is the weather monitoring based on computer network the graphical display of the desired effect of the application service. After, however, had a target to analyze the weather prediction condition now, for now the application of the domestic meteorological drawing technology is not widely, since each drawing software requirements and rules are not the same, lead to meteorological information graphics commands need to switch in different scripts, programs, caused great trouble to staff. So, analyze the meteorological data information is the premise of graphics is to switch from tedious and complicated procedures, let the meteorological information data, the researchers have more time for more detailed meteorological information visualization display of further research.
