Marine Meteorology & Weather Routing

Pressure patterns drive wind; air masses and fronts drive weather changes. Reading a synoptic chart lets the navigator anticipate rather than react.

A tropical cyclone is the most dangerous weather a ship can meet. Recognising the approach and manoeuvring by the semicircle rules is a survival skill.

Ships are both consumers and producers of marine weather data. A careful shipboard observation improves the forecast the whole fleet uses.

Weather routing selects the track that best satisfies safety, schedule and fuel objectives given forecast conditions — dynamically, as the forecast changes.
