Abstract
The wind breeze effect on the Todos Santos Bay, Baja California summer currents were analyzed through various numerical experiments, including the coupling of an oceanic and atmospheric model. It was found that the average currents and their variability are modified by the sea breeze, mainly in the shallow region (<40 m) and in the superficial layers (>5 m). The bay average circulation was found to be cyclonic in all the experiments. However, in the presence of sea breeze, the cyclonic circulation was less intense. The lower intensity was due to the breeze-synoptic wind interaction that inhibits the positive curl wind stress in shallow regions of the bay. Consequently, the Ekman pumping was suppressed, and the mixing of surface layers was promoted. Numerical evidence shows that the breeze was the main factor for the variability of the current above 5 m depth. A possible mechanism that explains the breezes' importance in the current's variability is that the diurnal wind-driven currents resonate with the bay inertial currents.
期刊介绍:
Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include:
Physical sedimentology and geomorphology
Geochemistry of the coastal ocean (inorganic and organic)
Marine environment and anthropogenic effects
Interaction of physical dynamics with natural and manmade shoreline features
Benthic, phytoplankton and zooplankton ecology
Coastal water and sediment quality, and ecosystem health
Benthic-pelagic coupling (physical and biogeochemical)
Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles
Estuarine, coastal and shelf sea modelling and process studies.
