A New Marine Auto-response Quantitative Wind Forecast System

AbstractGreat waves are usually introduced by and accompanied with strong winds; either of them is dangerous to the vessels on the sea. With the help of quantitative wind speed forecast, a seaman or a self-control system can decide whether to go along the original navigation route or switch to a safer one. A new 24/7 auto-response system was developed with the purpose of providing the future 1-5 days nautical surface wind trend per vessel's request. To lower the satellite communication cost, the messages are formatted in concise and quantitative text-mode (total < 200 bytes). The weather forecast data, retrieved at the nearest half degree grid point from an advanced global weather numerical model stored in a US server, is adjusted by statistical rending method according to the local conditions. The preliminary results were proven to contain great reliability and creditability
