改进的客观分析诊断图形软件

Updated Objective Analysis and Graphic Software

客观分析诊断图形系统是一款面向气象科研,得到广泛应用的二维气象绘图软件。根据气象科研工作和强对流天气分析研究的新需求,对该软件进行了改进,主要包括增加新数据接口、增加新算法、改进算法、简化操作等。改进的软件增加了静止卫星、新一代天气雷达和二进制格式点加工数据GRIdded Binary 2(GRIB2)等多种数据接口,增加了等熵面分析,交叉相关回波移动计算(CTREC)矢量计算,雷暴识别、追踪、分析和临近预报(TITAN)对流风暴追踪、强对流天气的监测和统计、多种新图形和图形裁剪等新算法,改进了等值线、流线、矢量、地图、不规则数据分布图等的生成、显示和编辑功能,还改进了软件中的数据处理、操作方式和输出图像效果。新软件仍存在一定不足,其功能还需要进一步增强。

＂Objective Analysis and Graphic System＂ is a populated two-dimension meteorological plotting application with friendly graphic interface,which runs on Microsoft Windows.The updated software supports many new kinds of meteorological data interface,such as the geostationary satellite data,the new generation weather radar data,and the GRIdded Binary 2（GRIB2） format data.Some new meteorological algorithms were developed in the new software,which are the isentropic analysis,the CTREC vector calculation, the TITAN convective storm tracking,lots of new kinds of graphs,the graphic clipping,and so on.The creation,drawing and editing of the contour,streamline,vector,post,geographic maps were improved in the new software.The data processing,the operation of user,and the output images were also bettered in the new software.However,the new software has also some shortages and need to be further improved in the future.
