Fecha de publicación: | 2005 | Editor: | Taylor & Francis | Citación: | Journal of Atmospheric and Ocean Science 10(4): 309-324 (2005) | Resumen: | Thermohaline variables were simultaneously measured, July 17, 2000, at four Galician rias under favourable upwelling conditions to analyse upwelling intensity. The intensity of coastal upwelling is shown to be strongly dependent on the wind pattern. The maximum amplitudes of wind stress were observed at the western coast (0.30 Nm−2) with southward direction (favourable to upwelling) and these are shown to be related to low temperature (12°C) and high salinity (35.8) in the estuaries mouth. From Cape Finisterre to Cape Estaca de Bares the wind stress showed a lower magnitude (0.05–0.10 Nm−2) with a direction oblique to the coast. The temperature showed an increase (14°C) and the salinity a decrease (35.4) because the lower upwelling intensity at this part of the coast. The observed decrease in upwelling from south to north is not an isolated event, since the measured wind conditions are persistent during summer months, at least in the period with available QuikSCAT data (1999–2004). | Descripción: | 16 páginas | Versión del editor: | http://dx.doi.org/10.1080/17417530601127480 | URI: | http://hdl.handle.net/10261/55791 | DOI: | 10.1080/17417530601127480 | ISSN: | 1741-7538 |
