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...

Storm surge scenarios for Hamburg

Abstract A scenario for future storm surge heights for the tide gauge of Hamburg St. Pauli is constructed on the basis of results from a regional model for Cuxhaven. Under the A2 emission scenario, an increase of the mean annual maximum water level of about 0.1724 m appears possible and plausible for the time horizon of 2030. In Cuxhaven, an increase of 0.14 may be expected in this scenario. In...

Rising hazard of storm-surge flooding.

The 2017 Atlantic hurricane season is one for the history books. It has blown a number of records out of the water. Harvey dumped more rain on the United States than any previous hurricane. Irma maintained the highest category 5 longer than any storm anywhere in the world. September 2017 has accumulated themost cyclone energy of any month on record in the Atlantic. Last, but not least, if early...

Grid Convergence Studies for the Prediction of Hurricane Storm Surge

The focus of this paper is a systematic determination of the relationship between grid resolution and errors associated with computations of hurricane storm surge. A grid structure is sought that provides the spatial resolution necessary to capture pertinent storm surge physics and does not overdiscretize. A set of numerical experiments simulating storm surge generation over 14 grid discretizat...
