Abstract
In December, 1975, an upwelling study was conducted at Punta Curaumilla near Valparaiso, Chile. Previous work (Silva, 1973) had indicated a zone of relatively intense upwelling around this point of land. In the present study , a bathythermograph survey confirmed the presence of the intensification, identified as a tongue of cool water extending seaward and equatorward of the point. Following Arthur\u27s (1965) scale analysis it is suggested that the acceleration of relative vorticity past the point of land is responsible for intensification...
