The theory of similarity for wind-driven seas is applied to the physical analysis of the problem of sea state bias (SSB) in altimetry measurements. Dimensionless wave steepness and pseudo-age derived from altimetry measurements are expected to provide physically relevant and accurate enough SSB estimates. Analysis of Jason-1,2,3 and SARAL/AltiKa data within the approach shows the similarity and robustness of SSB distributions re-casted onto space of wave pseudo-age and steepness. This result is considered as a ground for developing a new parametric model of SSB and for analysis of underlying physical effects.
Investigation of the interaction between oceanic heat fluxes and formation of the geopotential gradient fields in the middle troposphere during meridional and zonal processes has been carried out by applying linear correlation analysis. Analysis of the spatial distribution of the correlation coefficients has demonstrated that the structure of the interaction of heat fluxes in the North Atlantic with the geopotential gradient field in the middle troposphere over the Atlantic-European sector differs in periods with the predominance of meridional and zonal circulation forms, which indicates the significant role of the ocean heat flow in the formation and development of circulation regimes in the atmosphere.
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.
