The quantity and observational frequency of meteorological data by surficial automatic station are increasing. The transmission mode has developed from the traditional text mode to the message transmission mode. These changes make higher requirement for data processing timeliness. In this paper, we used Storm Flow Technology on decoding and warehouse of surficial automatic station data. It used Spout to connect external data sources, and convert data into Tuple, and then transmit to Bolt-decode, Bolt-warehouse and Bolt-DIEI. They can be used to real-time warehouse, monitoring, and quickly adjust system resource. Compared with the traditional simplified process, the stability, processing efficiency and expansibility of the application have been greatly improved.
