Current variability by wave propagation in Todos Santos Bay, Baja California, Mexico

Current variability by wave propagation in Todos Santos Bay, Baja California, Mexico

The temperature, velocity, and sea level fields for a summer climatological month (August) were analyzed using tridimensional and baroclinic model outputs in Todos Santos Bay (TSB), Baja California, Mexico. The numerical model was forced with wind (nonstationary), heat flux, and California Current S...

The numerical model was forced with wind (nonstationary), heat flux, and California Current System climatology on the open boundary. The 3- to 5-day current variability is related to a baroclinic wave traveling towards the northwest of the bay. Wave travel periodicity was due to the release of accumulated water from the Ensenada–Punta Banda Estuary (E–PBE) region. Local wind stress causes southeastward water flow and, given the TSB geometry, water accumulates in the E–PBE region. Weakening wind stress was the main cause of water release. In addition, complex empirical orthogonal function analysis found that outer TSB disturbances cause sea level variability.  A partir de las salidas de un modelo tridimensional y baroclínico, se analizaron los campos de temperatura, velocidad y superficie libre del mar para un mes climatológico de verano (agosto) en la bahía de Todos Santos (BTS), Baja California, México. El modelo numérico se forzó con viento (no estacionario), flujos de calor y en las fronteras abiertas con climatología que incluyó al Sistema de la Corriente de California. Se encontró que la variabilidad, de 3 a 5 días, del campo de velocidad está relacionado con la propagación, hacia el noroeste de la bahía, de una onda baroclínica. La periodicidad de la propagación de la onda se debió a la liberación de agua acumulada en la región entre Ensenada y el estero de Punta Banda (E-EPB). Se encontró que el esfuerzo del viento local es la causa del transporte de agua hacia el sureste, y debido a la geometría de la BTS, el agua se acumula en la región E-EPB. La relajación del esfuerzo del viento fue la principal causa de la liberación de agua acumulada. A partir del análisis de funciones empíricas ortogonales complejas, se encontró que también las perturbaciones provenientes del exterior de la BTS causan variabilidad en la superficie libre del mar. 2017-09-29 2021-06-03T03:55:36Z 2021-06-03T03:55:36Z 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/2775 10.7773/cm.v43i3.2775 https://hdl.handle.net/20.500.12930/7534 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2775/1933 Copyright (c) 2017 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 43 No. 3 (2017); 191-201 Ciencias Marinas; Vol. 43 Núm. 3 (2017); 191-201 2395-9053 0185-3880
