In order to improve the operational capability of meteorological emergency support, the surface meteorologicaldata reportmaking system with mobile phone was developed. The systm has the features of low requirement for support environment, high compatibility, objectoriented programming, and modularized structure. The functions and the operating sheme of the system in emergency are described in detail, and the problems encountered during the developing process of the system with J2ME and the corresponding countermeasures are discussed, including floatingpoint operations, special phenomenon processing, packet transmission, program compatibility, memory processing, as well as the practical application of the system and development proposals.
