Numerical modeling of the coastal circulation off northern Baja California and southern California

Seasonal behavior of dissolved cadmium and Cd/PO4 ratio in Todos Santos Bay: A retention site of upwelled waters in the Baja California peninsula, Mexico

“…The fact that the CUI values were slightly higher in the spring and summer than those of fall and winter indicates that some other processes were responsible for bringing deeper subsurface waters closer to the surface during springtime. Although it is beyond the scope of this work, in addition to the coastal upwelling process typically produced by along-coast winds, inhomogeneities in the wind field can also bring deep waters towards the surface off TSB (Pérez-Brunius et al, 2007;Mateos et al, 2013). Offshore the coast of California and Baja California, a positive wind stress curl drives a surface divergence, lowering sea level and pumping up cold subsurface water to replace the surface water (Beg-Paklar et al, 2009).…”

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

“…El efecto β permite la propagación de ondas libres (e.g., ondas de Rossby) hacia fuera de la costa, lo que modifica la estructura de densidad y contribuye a la formación de un gradiente de presión a lo largo de la costa que ayuda a la generación de la CSS a lo largo de la frontera este (Batten 1997). Frente a la costa norte de Baja California, entre 31ºN y 32ºN, la CCS y la CSS son inestables y ocasionan gran variabilidad en la región (Mateos et al 2013). Se ha encontrado que la variabilidad de la circulación frente a la costa norte de Baja California tiene un impacto sobre la variabilidad de la circulación dentro de la BTS (Mateos et al 2009).…”

“…The β effect allows the offshore propagation of free waves (e.g., Rossby waves), modifying the density structure and contributing to the formation of an alongshore pressure gradient that contributes to the development of SSC along the eastern boundary (Batten 1997). Off the northern Baja California coast, between 31ºN and 32ºN, the SCC and SSC are unstable and cause great variability in the region (Mateos et al 2013). Variability in water circulation off the northern Baja California coast has an impact on water circulation variability in TSB (Mateos et al 2009).…”

“…All model forcings and configurations were built based on climatologies, except wind stress, which was treated as described by Mateos et al (2013). The daily wind stress and heat flux data were obtained from the North America Regional Reanalysis with a spatial resolution of 32 km.…”

“…The initial conditions and daily forcings in the open boundaries were obtained from a previous model validated by Mateos et al (2013). The formerly mentioned model was executed with 2 nested grids.…”
