Beron-Vera FJ Hadjighasem A Xia Q Olascoaga MJ Haller G 2019 The emergence of coherent Lagrangian swirls (CLSs) among submesoscale motions in the ocean is illustrated. This is done by applying recent nonlinear dynamics tools for Lagrangian coherence detection on a surface flow realization produced by a data-assimilative submesoscale-permitting ocean general circulation model simulation of the Gulf of Mexico. Both mesoscale and submesoscale CLSs are extracted. These extractions prove the relevance of coherent Lagrangian eddies detected in satellite-altimetry-based geostrophic flow data for the arguably more realistic ageostrophic multiscale flow. application/pdf https://sonar.ch/global/documents/199724 eng info:eu-repo/semantics/altIdentifier/doi/10.1073/pnas.1701392115 info:eu-repo/semantics/altIdentifier/pmid/29507245 info:eu-repo/semantics/openAccess Proceedings of the National Academy of Sciences of the United States of America. - 2019 Lagrangian coherence high-resolution ocean models mesoscale eddies satellite altimetry submesoscale eddies Coherent Lagrangian swirls among submesoscale motions. http://purl.org/coar/resource_type/c_6501
