As the birds arrived and passed over me, I felt a current of air that surprised me.

当鸽群逐渐飞近掠过我的头顶，一阵惊悚让我的心痉挛收紧。

That divide is the jet stream or strong currents of air created when warm and cold air masses meet.

这条界线是暖气团和冷气团相遇时产生的急流或强流。

It went way up above the clouds, so far that a current of air struck it and carried it many, many miles away.

“轻气球飘荡在云上面，上空有一种气流，向那老远的地方推着它，把它带走很长一段路。

A cold current of air passed them, and the light shot up for a moment in a flame of murky orange.

一股冷气流从他们身边掠过，灯光瞬间升起，变成了暗橙色的火焰。

From there, they'd have to wait for the currents of air to blow them closer to a wall or try to " swim" back through the air.

他们不得不在那儿等着气流把他们吹到离墙更近的地方，或者努力在空中“游”回来。

It was too dark to see a shape; all that happened was that the darkness moved, as a curtain might stir in a current of air.

天太黑了，看不见人影； 所发生的一切只是黑暗在移动， 就像窗帘在气流中移动一样。

The currents of air that the walls of the ship direct upwards, as well as in the line of its course, are enough to give the great bird with its immense wings sufficient sustenance and progress.

沿船体的上升的气流和沿航线向前的气流，给这种巨翼大鸟以足够的浮力和推力。
