DOWNSCALING EFFECTS ON MODELLING WAVES, TIDES AND STORM SURGE

Downscaling Effects on Modelling Waves, Tides and Storm Surge

This paper presents the results of downscaling effects when modelling waves, tides and storm surge using a nested modelling system. In this study, the coupled POLCOMS/ProWAM models are used, with 3 nested computational domains, the largest of which covers part of north-eastern Atlantic Ocean with a coarse resolution grid and the smallest covers the surrounding waters of south-west Cornish coast...

Effects of Winds, Tides, and Storm Surges on Ocean Surface Waves in the Japan/east Sea

Wind driven oceanic surface waves have a major impact on marine activity, especially near the coastal regions. Strong winds associated with winter storms induce storm surges along the west coast of Japan. Combined high wind conditions, tides, and storm surges can have a tremendous impact on the surface wave fields. Accurate wave forecast becomes an important issue at various operational forecas...

Modelling the Tracy storm surge – implications for storm structure and intensity estimation

The results of hydrodynamic storm surge modelling are used to inform and construct a detailed quantitative description of the possible changing structure and intensity of severe tropical cyclone Tracy as it proceeded across Beagle Gulf to landfall at the City of Darwin in 1974. The measured storm surge is used as an independent wind calibration proxy to augment the measured eyewall winds and pr...

Modelling waves and surges during the 1953 storm.

Waves and sea levels have been modelled for the storm of 31 January-1 February 1953. Problems in modelling this event are associated with the difficulty of reconstructing wind fields and validating the model results with the limited data available from 50 years ago. The reconstruction of appropriate wind fields for surge and wave models is examined. The surges and waves are reproduced reasonabl...
