Extreme waves in the southern Baltic Sea

Extreme waves in the southern Baltic Sea

Freak waves are unique phenomena that appear unexpectedly on the ocean surface. These waves are not only a danger to fishermen and yachtsmen, but are also capable of damaging large vessels and offshore and coastal structures. The available field measurements that provide insight into the origin and...

Estas olas no sólo son un peligro para pescadores y navegantes, sino que también son capaces de dañar embarcaciones grandes y estructuras costeras y en alta mar. Son pocas las mediciones de campo disponibles que proporcionan información sobre el origen y la física de las olas gigantes, por lo que el objetivo principal de este estudio fue analizar una base de datos de 19,025 registros del oleaje en la parte sur del mar Báltico para obtener información sobre la frecuencia, los parámetros y las condiciones prevalecientes de la formación de éstas. Para estudiar la naturaleza compleja de las olas gigantes, se obtuvieron parámetros espectrales y estadísticos de los estados de mar propensos a olas gigantes usando varias herramientas. El estudio mostró un gran número de olas gigantes, incluyendo olas de más de 12 m de altura, y que estas olas pueden sobrepasar los 20 m de altura durante tormentas severas en el mar Báltico. Se requieren mediciones de oleaje de distintos sitios para recabar mayor información sobre la física de olas gigantes y eventualmente poder desarrollar un sistema de predicción y advertencia para evitar desgracias. 2016-06-15 2021-06-03T03:55:29Z 2021-06-03T03:55:29Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2599 10.7773/cm.v42i2.2599 https://hdl.handle.net/20.500.12930/7502 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2599/1589 Copyright (c) 2016 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 42 No. 2 (2016); 123-137 Ciencias Marinas; Vol. 42 Núm. 2 (2016); 123-137 2395-9053 0185-3880
