It adopts the "page image buffer technology" and achieves a secondary radar products online animation, so that forecasters can accurately understand the evolution of the radar echoes in a span of time. Its background distribution system is based on C / S structure. And its prospects site systemis based on B / S structure. It plays the maximum role of data sharing in network technology.
