A new hydrodynamical model interpreting the synthetic aperture radar (SAR) imaging of a kind o f ocean objects is proposed. It is based on the perturbation analysis o f the wave height spectrum balance equation. An appropriate form of equilibrium wave height spectrum is deduced and then used to obtain the relative variation rate of the spectrum perturbation t o its equilibrium state. Such variation rate reflects directly the features o f a kind o f ocean objects on the S A R images.
Surface meteorological variables and heat fluxes in the Bering Sea obtained from Chinese Arctic buoys and U.S. National Data Buoy Center buoys are compared with seven products. The seven products comprise six reanalysis products, that is, the European Centre for Medium-Range Weather Forecasts Interim Reanalysis (ERA-Interim), Japanese 55-year Reanalysis (JRA-55), Modern Era Retrospectiveanalysis for Research and Applications Version 2 (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
