A Nearshore Wave and Current Operational Forecasting System

ALVAREZ-ELLACURIA, A.; ORFILA, A.; OLABARRIETA, M.; MEDINA, R.; VIZOSO, G., and TINTORÉ, J., 2010. A nearshore wave and current operational forecasting system. Journal of Coastal Research, 26(3), 503–509. West Palm Beach (Florida), ISSN 0749-0208. An operational forecasting system for nearshore waves and wave-induced currents is presented. The forecasting system (FS) has been built to provide r...

Observations of nearshore circulation: Alongshore uniformity

[1] Nearshore circulation, observed for 4 months on a 200-m-long stretch of natural beach during the SandyDuck field experiment, is shown to be alongshore uniform. An alongshore momentum balance between (wind and wave) forcing and bottom stress, cross-shore integrated between the shoreline and approximately 4 m water depth, holds on each of five instrumented cross-shore transects (skill 0.87). ...

Morphology of the ring current derived from magnetic field observations

Our examination of the 20 years of magnetospheric magnetic field data from ISEE, AMPTE/CCE and Polar missions has allowed us to quantify how the ring current flows and closes in the magnetosphere at a variety of disturbance levels. Using intercalibrated magnetic field data from the three spacecraft, we are able to construct the statistical magnetic field maps and derive 3-dimensional current de...

Assimilation of Observations into Coastal and Nearshore Circulation Models

OBJECTIVES Develop an assimilation capability for fields of surface currents from Doppler radar systems. Continue the investigation and testing of an assimilation capability for surface wave effects. Use observations of coastal and shelf parameters to determine spatial decorrelation scales. Ascertain changes in these scales when determined from fields from prognostic simulations of a fine-scale...
