A remotecontrolled groundbased flare seeding system through mobilephone Short Message Service (SMS) was developed. Since the ignition signals are issued by means of SMS, the system can be operated remotely and automatically. The system consists of a smoke generator, flares, computer and the related software. A total of 36 flares can be placed in the generator at one time. Each flare contains 500 g of BR91Y pyrotechnics (7.5 g AgI). The control system can work anywhere within the coverage of the mobilephone network. The system is controlled by a computer, being easy to use. It was applied in April and May 2006 in the Yulong Mountain region to enhance snowfall. The problems emerged during the experiment are discussed, and some solutions are presented. The experiment shows that the system performs well and has great potential in application.
