"Red sky at night, sailor's delight. Red sky in morning, sailor's warning"

 

No scientific phenomena concern us as much as the daily evolution of weather systems. We live in a culture where weather, the state of the atmosphere at a given time and place, helps us define regional cultural variations. Superimposed on the regular rhythms of the atmosphere are more extreme events that threaten lives, disrupt transportation systems, and cause destruction. Approximately 90% of disaster declarations are weather related.  

 

Advances in weather forecasting and satellite communications provide unprecedented amounts of weather information to ship masters. The use of these aids to the best of their capability will assist the ships to reach their destinations safely.

 

It is prudent to utilize the advances in weather forecasting, satellite communications and computer technology to enhance the safety and efficiency of ship operations. The extensive use of technologies and in depth research carried out by the World Meteorological Organisation help ship masters and the shipping fraternity to carry out their tasks safely. The use of advanced technology is indeed a blessing to the future generations of sailings.
