Simulation of sea storms including multivariate storm evolution

30 Dec 2018-Vol. 1, Iss: 36, pp 35-35
TL;DR: In this article, a new method for the simulation of storms is proposed which takes into account the multivariate evolution of the storms, allowing to innovate in the form of each simulated storm, for all the variables involved.
Abstract: A new method for the simulation of storms is proposed which takes into account the multivariate evolution of the storms, allowing to innovate in the form of each simulated storm, for all the variables involved. The method is based on two novel aspects: (a) measured storms are grouped using clusters techniques and a set of average evolution forms is defined for each cluster, one for each of the variables involved, and (b) a Vector Autoregressive model is fitted to the differences between the average evolution of each variable and the actual measured evolutions. The ability of the methodology to properly reproduce the joint probability distribution of all the variables involved is demonstrated for a case study at the mid Rio de la Plata northern coast.

TL;DR: In this article, the XBeach-1D model was used to assess the differences in simulated erosion and flooding associated with real and synthetic storm definitions, which generated considerable differences in terms of wave power and timing at the peak of the storm.

TL;DR: The extremal Rayleigh distribution as mentioned in this paper is an approximation to the probability distribution function for the maximum wave distribution function in time-varying storms and computed for a large number of historical hurricanes.
Abstract: The function, which is called the extremal Rayleigh distribution, is found to be an accurate approximation to the probability distribution function for the maximum pro a hurricane with time-varying intensity A formula is developed for the maximum wave distribution function in time-varying storms and computed for a large number of historical hurricanes The extremal Rayleigh function was found to be a very accurate approximation in all cases Two parameters are shown to be interpretable in terms of an equivalent uniform intensity storm as the reciprocal of the logarithm square wave height and the logarithm of the number of waves in the storm, respectively Data from Hurricane Carla was analyzed to determine the parameters which best described the probability behavior of the larger waves in each 20 min record Statistical formulas and tables are given to facilitate probability use of the extremal Rayleigh probability law in coastal engineering and hurricane research
