An Objective Analysis Software for Meteorological Elements

摘要:

介绍了一套在VC^＋＋环境下开发的气象要素场客观分析软件。该软件利用三角形网格进行等值线分析，采用3次B-样条随线平滑，采取逆距离加权法插值；封装了CxImage图形包的部分功能，实现了内存图形的快速绘制与存储；通过菜单信息列表、产品输出列表和控制信息列表等接口设计，成功地实现了客观分析的自动化控制，灵活性大大加强，既可作为独立平台，也可作为模块，可自动化，也可人机交互；借助于Windows的计划任务，实现了无人工干预的山东省级实时雨情业务的全自动化图形服务。

Abstract:

An objective analysis software for meteorological elements developed under VC environment is described. It makes isoline analysis by means of triangle grids and cubic B-spline curve smoothing,and counter-distance weighting method for interpolation. Some functions of the CxImage graph package were sealed so as to realize the quick generation and storage of graphics in the memory. Through the interface design of data menu, product output list, and information-control list, automatic objective analysis was realized successfully. The software can be used as an independent platform or as a module, and can be operated automatically or manually. The real-time graphic rainfall display across Shandong Province without any manual intervention was realized under Windows. The software has been used in the Shandong provincial-level meteorological service and research.
