沂沭泗水系气象信息图形可视化的实现

通过对VB和delphi混合编程,在充分利用Surfer强大绘图功能的基础上,实现了沂沭泗水系气象等值线图的自动绘制。对Surfer软件功能深入研究发现,Surfer与VB编程语言之间可以实现ActiveX自动化连接,将Surfer强大的绘图功能与VB编制交互界面程序的优势相结合,通过VB调用Surfer的绘图函数,实现沂沭泗水系气象信息填图、等值线绘图及色彩填充,并能动态地显示与输出这些图形。实时气象资料的图形化显示有助于提高短时临近天气预报水平,为人工增雨指挥作业提供更好的气象服务,对防御宿迁的雷雨大风冰雹等强对流天气意义十分重大。

Automatically Drawing of Meteorological Line in River System of Yishu-Si

Based on the full use of mighty plotting functions of Surfer,automatically drawing of meteoro-logical line in river system of Yishu-Si can be realized by using mixed-Language Programming with Visual Basic and Delphi.By means of powerful capability of Surfer,in combination with Visual Basic programming language,the ActiveX link can be set up.Calling the plotting functions of Surfer by Visual Basic,the weather information,line plotting and color filling of the Yishu-Si river system are realized automatically,as well as their dynamic display and export.The graphic display of real-time meteorological data is helpful in improving the level of weather forecasting,provides better meteorological service for operation command of precipitation enhancement and is of significance in preventing severe convective weather in SuQian,such as thunderstorm,gale and hail.
