Weather

The weather is a factor in many maritime incidents. Even if it is not the cause of the incident, it often plays an adverse role by hampering rescue efforts and having a detrimental effect on the likelihood of survival at sea. It also has an effect on whether some vessels, particularly small craft, will proceed with scheduled activities.

Yue Wu, one of our graduate students, is studying the effects of weather on incidents and on traffic behaviour, and quantitatively determining their relationship.

An example of the data used in our analysis is shown in the first figure, which displays the monthly mean precipitation in North America. The lighter blue grid squares represent a lower precipitation while the darker is represent a heavier precipitation. These data have been aquired from the U.S. National Oceanic and Atmospheric Association (NOAA), and processed by MARIN for the purposes of maritime risk analysis.


The second figure depicts the wave heights in Atlantic Canada at a particular time of day. These data were accessed through a research collaboration with Environment Canada (EC) and result from a Wind-Wave model developed by Oceanweather Inc.
