And there's something called vertical wind shear, which is a change in wind speed or direction with height.

还有一种叫做“风垂直切变”的东西，指的是风速或风向随高度的变化。

NOAA expects sea surface temperatures to be average or above average, and it doesn't expect a lot of vertical wind shear which can weaken hurricanes.

NOAA 预计海面温度将处于平均水平或高于平均水平，并且预计不会有很多可以削弱飓风的垂直风切变。
