METEOROLOGY FOR SAFE NAVIGATION IN TROPICAL & EXTRATROPICAL CYCLONES
Code No 695
Time: 37 Mins
Routine passages for many ships include areas where high winds and rough seas
can occur due to the proximity of cyclones.
Taking the example of the sea areas around Japan and the North Pacific, the video
first explains how air masses influence and cause the generation of cyclones.
The video shows how depressions can develop into cyclones, also where they tend to
start and how they subsequently behave. The theory is illustrated by looking in detail
at the behaviour and movement of actual recorded cyclones. This explains how
exceptionally high waves become associated with cyclones; these high waves cause
casualties at sea.
Ships should avoid areas of high waves by using weather routing, to provide a
recommended route to avoid areas of high waves. The video shows how ship speed
in waves is obtained so making it possible to find the optimum route for the shortest
voyage time.
The video further explains how to use observations of wind speed and direction
onboard to stay safe in the vicinity of a cyclone. Seafarers need to know how to use
available meteorological knowledge and available forecast data to ensure safe and
cost effective ship operation.
