Storm waves in Canadian waters : A major marine hazard

ABSTRACT

In this paper, an overview of storm waves associated with intense weather systems affecting the east and west coasts on Canada is presented. The paper presents the wave climatology of the east and west coasts in terms of the 100-year significant and maximun wave heights and further analyses the directional distribution of wave heights at selected locations in the Canadian east and west coasts offshore. The paper also analyses wave hazards associated with storm waves in the Beaufort Sea as well as the Canadian Great Lakes region. A section on ocean wave modelling provides a brief history of the development of ocean surface wave models and its present status. The paper further considers the impact of climate change scenarios on wave hazards and finally examines mitigation measures in terms of wave products available from operational models and related wave climatology.(AU)
