单词	downwelling
释义	downwelling /ˈdaʊnwɛlɪŋ / noun [mass noun] The downward movement of fluid, especially in the sea, the atmosphere, or deep in the earth: coastal downwelling leads to in-transport of coastal water [count noun]: continents aggregate over cold downwellings in the mantle... One interpretation is that the ‘fast’ regions are simply colder downwellings and that slow regions are hotter upwellings in a compositionally homogeneous mantle. Convergence of these fronts led to downwelling of surface waters and upwelling of deep waters during the stratified period. Those upwellings and downwellings imply that at the surface there is a general southward wind between 0 and 30 lat, a northward wind between 30 and 60 lat, and a southward wind between 60 and 90 lat. adjective Characterized by or undergoing downwelling: downwelling mantle... Anoxia is then triggered at t = 0 by reducing the oxygen concentration in the downwelling water by 50%. In this model run, anoxia is triggered by halving the O2 content of the downwelling water. In such instances, a rigid coupling of plates to convection cells would imply the unusual scenario of upwelling along an expanding ring, with a downwelling column inside it.
