The Gulf Stream (GS) transports a massive amount of heat northward to high latitudes and releases sensible and latent heat to the atmosphere, playing an important role in the North Atlantic and European climate change. The change trends of the GS transport and pathway are still uncertain to date. Our analyses of altimeter observations from 1993 to 2016 indicate that the linear trends in surface maximum speed, transport, and latitudinal location of the GS are significant east of 61° W at the 95% level while they are small and not significant between 72° W and 61° W. The weakening trend of the GS during the period from 1993 to 2016 is accompanied with a southward-shifting path, which is associated with the decline of the North Atlantic Oscillation (NAO) and possibly reduction in the Atlantic meridional overturning circulation (AMOC).

1993年至2016年墨西哥湾流的遥感线性趋势

墨西哥湾流（GS）将大量热量向北输送到高纬度，并向大气释放明显的潜热，在北大西洋和欧洲的气候变化中发挥了重要作用。迄今为止，GS运输和途径的变化趋势仍不确定。我们对1993年至2016年测高仪观测的分析表明，GS的最大表面速度，运输和纬度位置的线性趋势在95％的水平上在61°W以东显着，而在72°W之间则很小且不显着在1993年至2016年期间，GS的减弱趋势伴随着向南移动的路径，这与北大西洋涛动（NAO）的下降以及大西洋子午俯仰环流的减少有关（AMOC）。
