NUMERICAL MODELLING OF TROPICAL CYCLONE STORM SURGE

Tropical Cyclone Flooding: Not Just a Coastal Storm-Surge Phenomenon

Inland riverine flooding from tropical cyclones (TCs) is responsible for significant economic losses in the United States. Yet, most hurricane loss assessment efforts are focused on coastal areas. Hurricane Irene, which struck the U.S. east coast in 2011, provides a recent and poignant example: while intense media coverage and preparation and evacuation activities focused on the projected coast...

Consideration of Applicability of Stochastic Tropical Cyclone Model for Probability Assessment of Storm Surge

Storm surge risk is basic and important information for design of coastal structure, but its probability assessment is difficult because the frequency of devastating TC is not so high. Furthermore, storm surge damage is very sensitive to not only its intensity but also its track and translation speed. Therefore, the estimation of occurrence probability of devastating disaster from our limited o...

Statistical modelling of tropical cyclone tracks: modelling cyclone lysis

We describe results from the fifth stage of a project to build a statistical model of tropical cyclone tracks. The previous stages considered genesis and the shape of tracks. We now consider in more detail how to represent the lysis (death) of tropical cyclones. Improving the lysis model turns out to bring a significant improvement to the track model overall.

A CYCLONE INDUCED STORM SURGE FORECASTING MODEL FOR THE COAST OF BANGLADESH WITH APPLICATION TO THE CYCLONE `SIDR'

The coast of Bangladesh has a specialty in terms of high bending and many off- shore islands. Incorporation of the coastline and island boundaries properly in the numerical scheme is essential for accurate estimation of water levels due to surge. For that purpose a numerical scheme consisting of very fine mesh is required along the coastal belt, whereas this is unnecessary away from the coast. In...
