Patterns of sea-surface temperature which come and go, rather than absolute levels that continue to rise, may be the important thing.

海洋表面温度的模型是时而升高时而下降，而非持续维持上升方向，这可能是重要的原因。

Dr Solomon suspects the former, because of the way the relationship between the stratosphere and the sea-surface temperature has changed.

Solomon博士倾向于前者，理由是平流层和海洋表面温度两者关系的改变方式。

Even though one or two degree Celsius rise in sea surface temperature for a relatively short amount of time can cause bleaching.

即使海面温度在短时间内升高一到两摄氏度，也可能会引起褪色。

This would make them whiter so they reflect more sunlight back into space, reducing the sea surface temperature - which is the primary driver of hurricanes.

But by the Berkeley team's analysis, the global temperature correlates more closely with the state of the Atlantic Multidecadal Oscillation (AMO) index - a measure of sea surface temperature in the north Atlantic.

Kearns and a team of scientists led by Alan Strong of NOAA's National Environmental Satellite, Data and Information Service analyzed sea surface temperature data from the agency's polar-orbiting satellites from 1984 through 1996.
