摘要

[1]对观测记录的研究表明，在1960-1985年的25年期间，热带大西洋近地表水域以每十年0.1 psu的速率经历了一次大规模的盐渍化。最近十年，这一趋势发生了逆转。虽然盐度的年际变化与降水有关，但我们将盐度的年代际变化至少部分归因于热带深处风的低频变化及其在改变上升流和可能的蒸发速率方面的作用。

Low frequency variation of sea surface salinity in the tropical Atlantic

[1] Examination of the observational record suggests that the near-surface waters in the tropical Atlantic underwent a major salinification during the twenty-five year period 1960–1985 at a rate of 0.1 psu/decade. A reversal of this trend has occurred during the most recent decade. While year-to-year changes in salinity are related to precipitation, we attribute decadal changes in salinity at least in part to low frequency changes of winds in the deep tropics and their role in altering both upwelling and possibly, evaporation rates.

期刊介绍： Geophysical Research Letters (GRL) publishes high-impact, innovative, and timely research on major scientific advances in all the major geoscience disciplines. Papers are communications-length articles and should have broad and immediate implications in their discipline or across the geosciences. GRLmaintains the fastest turn-around of all high-impact publications in the geosciences and works closely with authors to ensure broad visibility of top papers.
