“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.
