Analysis of the SSH anomalies in response to the passage of two PLs is performed using satellite altimeter measurements and model simulations. The observed SSH anomalies contained an inverse barometer correction; therefore, they were presumably caused only by the action of surface wind stress in the PLs. The SSH anomalies along the satellite altimeter tracks had the shape of a trough, with the lowest surface height near the center of the PL. The observed anomalies were well distinguished within about one day after the PL passage, with the largest negative value of 0.6 m. The SSH anomalies are analyzed using a simplified model of the ocean barotropic response to the surface wind stress, derived from the hourly wind fields provided in the ERA5 reanalysis dataset. The model quantitatively reproduced the SSH anomalies along most satellite altimeter tracks crossing the PL trajectories. The model simulations revealed that the largest negative SSH anomalies were observed in areas where the PL translation velocity was low and its moving direction changed with the trajectory curvature radius, which was much smaller than the barotropic radius of deformation. The estimated quasi-geostrophic current velocities corresponding to the SSH anomalies in the wakes of the PLs reached 0.15 m\/s, which were comparable to the current velocities observed in the Barents Sea.<\/jats:p>","DOI":"10.3390\/rs15174239","type":"journal-article","created":{"date-parts":[[2023,8,29]],"date-time":"2023-08-29T08:51:14Z","timestamp":1693299074000},"page":"4239","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["On Barotropic Response of Arctic Seas to Polar Lows: A Case Study in the Barents Sea"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8545-1761","authenticated-orcid":false,"given":"Vladimir","family":"Kudryavtsev","sequence":"first","affiliation":[{"name":"Satellite Oceanography Laboratory, Russian State Hydrometeorological University, 195196 St. Petersburg, Russia"},{"name":"Marine Hydrophysical Institute RAS, 299011 Sevastopol, Russia"}]},{"given":"Anastasiia","family":"Stokoz","sequence":"additional","affiliation":[{"name":"Satellite Oceanography Laboratory, Russian State Hydrometeorological University, 195196 St. Petersburg, Russia"}]},{"given":"Kirill","family":"Khvorostovsky","sequence":"additional","affiliation":[{"name":"Satellite Oceanography Laboratory, Russian State Hydrometeorological University, 195196 St. Petersburg, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Rasmussen, E.A., and Turner, J.
