The characteristics and requirements of the intensive automatic weather station (AWS) network for meso and smallscale weather systems are analyzed in combination with the specific geographic conditions of Chengdu and the existing groundbased meteorological sounding technology. The characteristics of some new mobile communication networks and technology, such as GPRS, CDMA1X, etc., are compared, and their intrinsic relation in operationality is discussed. On the basis of the former experiences in the construction of the AWS network, a more rational datacollecting and application model is put forward.
