【摘要】 随着国家经济建设的快速发展,各种现代化程度越来越高,加之国家对气象系统的重视和投入,大气探测的手段在不断提高,获得气象的要素越来越多,数据量越来越大,如何更加快速有效的用好这些数据和解析数据成为当前预报业务工作最为关心的问题之一。随着计算机的硬件发展,已经完全能够满足普通预报业务工作,各种数据的计算可视化层现在预报员面前已不再是奢望,利用国家巨型计算系统运算出的数值天气预报数据,已最直观的图片形式展现在各及预报员面前已成为事实。目前针对气象数据的可视化,尤其是二维数据的软件,在国内还不多,常用的气象显示分析软件,多为专业性较强,对于培养一个预报员的同时,还需要培养一批对该软件操作熟悉的业务人员,成本相对较高。因此,相对于各级气象部门来说,需要一种将观测资料和数值天气预报的大量数据进行有效的处理和显示,同时又要非常的快捷,使预报员能够直观同时快捷的了解最近的天气状况,做出准确的天气预报。本文介绍目前国内,气象数据的科学计算可视化的主要技术,考虑到使用意义和成本问题,主要分析国内外应用于气象的二维显示软件的特点和不足,基于GRDAS软件的特点和缺点,选择该软件开发支持,利用我国气象部门普遍使用的9210系统获得数值天气预报数据,开发适合气象部门业务预报的数据显示系统。更多还原

【Abstract】 With national economic development has developed rapidly, and high degree of modernization, the state of weather systems and atmospheric observation, and the means of steadily improved, meteorological elements of the quantity of data, more and more and more rapid and effective use these data and intuitive parsing data into the current forecast business is most concerned about the issue. As computer hardware development and was able to meet the ordinary work, data visualization of the floor now before the weatherman has ceased to be guilty of one country, the system of operation of numerical weather prediction data, has the most direct manifestation form of the picture in the front and the weatherman has become a reality. Present for meteorological data visualization and especially of a two-dimensional data software, at home is not much, the weather shows that software for analysis and professional strong, a forecaster with the same time, also need to train a group of the operation of the familiar business personnel, relatively high costs. Therefore, relatively to meteorological departments at all levels, need some materials will be observed and numerical weather prediction of a large number of effective processing and data show also be very quick and the forecaster to be able to direct and quick to understand the latest weather conditions and make accurate weather forecast.This at present the domestic and meteorological data visualization of scientific calculations of the main techniques used, consider the meaning and costs problems, mainly analyses and applied to meteorological software of a two-dimensional shows the characteristics and is based on GrADS software and shortcomings, the software development support, the use of meteorological department of our common use 9210 system numerical weather prediction data, the development of meteorological department for business forecast the data system.更多还原
