A brief introduction is made of two kinds of networking modes, and the background and status, as well as the significance in improving the density, automation, and precision of the surface meteorological observation network of two networking modes, are analyzed. Based on the application of two kinds of networking modes in Jiangxi Province in 2004, some discussions are made on the construction of the Integrated Automatic Meteorological Station Sounding Network and the assimilation of various sounding data as reanalyzed meteorological fields to provide service for numerical prediction models and the monitoring and warning of mesoscale severe convective weather.
