It is informed that the first set of wireless meteorological facsimile system operating for one year has been recognized by many shipping companies. Currently, marine meteorological facsimile image has fully covered coastal and offshore areas.
Marine ship navigation security is closely associated with marine meteorology and hydrological environment. Right now, there are three channels to for ships to come by marine meteorology and hydrological information. In comparison, the facsimile image information released by superpower broadcasting station in coastal regions is rich, boasting features like long prediction duration, and wide coverage, which is conducive to directly gaining insight into marine environment and its changes, and plays an instrumental role in ensuring navigation security on the sea, and emergency response rescue in the wake of the disaster.
In 1974, CMA set about meteorological facsimile operation. However, as the system was updated, the operation was brought to a halt in 2002.
The independent broadcasting of wireless marine meteorological facsimile products is the urgent demand for China to construct a marine power and enhance international competitiveness, as well as a responsibility to shoulder relevant international obligations as the member of International Maritime Organization. In 2014, marine wireless meteorological facsimile system project construction was relaunched. The first set of the system was officially placed into operation on January, 1, 2020. It was jointly developed by Donghai Navigation Safety Administration (DNSA) of Ministry of Transport, Shanghai Marine Observatory, and Typhoon and Marine Meteorological Forecast Center of China Meteorological Administration (CMA). In June, 2020, marine facsimile broadcasting service of Shanghai was incorporated into relevant documents of World Meteorological Organization (WMO).
Based on navigation demands, broadcasting contents have been enriched, which encompasses ground surface, weather, sea wave prediction images in East Asia, ground surface analysis images in North Pacific, and typhoon track images in Northwest Pacific provide by relevant meteorological departments of China. And the service signal covers a scope of over 2000 nautical mile (3704 km).
In 2020, DNSA has broadcasted all kinds of marine meteorological facsimile images totaling 5980. In the future, meteorological departments will further proactively coordinate relevant departments, consolidate top design, set up and improve marine meteorological facsimile product system, and optimize normalized user feedback mechanism.
