Based on civil aviation business processes, we systematically study  the original civil aviation meteorological information processing and transmission system. The research indicates that with the development of the civil aviation business, the original system is unable to meet the real-time performance demand, so we propose a new civil aviation meteorological information receiving and transmission scheme. Multi-node parallel processing technology, load balancing and main-memory database are adopted in this new model to facilitate the process of decoding, quality inspection and the storage and distribution of meteorological information. The new model has already been successfully applied in the civil aviation meteorological information processing and transmission proving system.
