摘要
We introduced query system of the historical high-altitude surface weather chart. Historical high-altitude surface data were converted to Grads data format. Grads as generation tool of the image, ASP was used to compile WEB page. By B/S mode, only user submitted necessary conditions for the image to server by client browser, historical high-altitude surface weather chart at corresponding time and height could be ob- tained. Without any procedures and related data, only needed client browser, user could use image conveniently to a large extent.
