The difference between tropical east and west Pacific sea-surface temperatures affects local and global climate, and most climate models suggest a weaker future gradient despite a recent observed increase. Research now suggests the recent trends are due to a transient delay in east Pacific warming driven by cold water upwelling and aerosols.

对未来热带气候变化的新见解

热带东太平洋和西太平洋海面温度之间的差异会影响当地和全球气候，大多数气候模型表明，尽管最近观察到了上升趋势，但未来梯度较弱。现在的研究表明，最近的趋势是由于冷水上升流和气溶胶导致东太平洋变暖的短暂延迟。
