- Storm-Source-Locating Algorithm Based on the Dispersive Nature of Ocean Swells. Jesús Portilla Multidisciplinaria (Ciencias Naturales y Exactas) WAM Swell ECMWF wind waves swell tracking The dispersion relationship of ocean waves in deep water dictates that the wave velocity depends on frequency. Waves of smaller frequencies travel faster than waves of larger frequencies. Therefore, at any remote location, for a specific storm event, the wave frequency and the time of arrival are related in a linear fashion. In the present work, this property is exploited in order to derive information about the distance of the originating storms and also about the time in which those storms take place. For this analysis, wave spectral data from the ECMWF (European Centre for Medium-Range Weather Forecasts) are used. The output is verified against parameters from the meteorological model, namely atmospheric surface pressure and wind velocity. The results show that the algorithm provides space and time information in consistency with the meteorological data. 2012 artículo científico 1390-5384 https://www.redalyc.org/articulo.oa?id=726180827011 en http://www.redalyc.org/revista.oa?id=7261 Avances en Ciencias e Ingenierías application/pdf Universidad San Francisco de Quito Avances en Ciencias e Ingenierías (Ecuador) Num.1 Vol.4
