SECOND PART
CHAPTER 19: The Gulf Stream
(continued)
Meanwhile I was carefully examining these unleashed breakers.
They measured up to fifteen meters in height over a length
of 150 to 175 meters, and the speed of their propagation
(half that of the wind) was fifteen meters per second.
Their volume and power increased with the depth of the waters.
I then understood the role played by these waves, which trap air
in their flanks and release it in the depths of the sea where its
oxygen brings life. Their utmost pressure--it has been calculated--
can build to 3,000 kilograms on every square foot of surface they strike.
It was such waves in the Hebrides that repositioned a stone block
weighing 84,000 pounds. It was their relatives in the tidal wave
on December 23, 1854, that toppled part of the Japanese city of Tokyo,
then went that same day at 700 kilometers per hour to break on
the beaches of America.
After nightfall the storm grew in intensity. As in the 1860 cyclone
on Réunion Island, the barometer fell to 710 millimeters. At the close
of day, I saw a big ship passing on the horizon, struggling painfully.
It lay to at half steam in an effort to hold steady on the waves.
It must have been a steamer on one of those lines out of New York
to Liverpool or Le Havre. It soon vanished into the shadows.
At ten o'clock in the evening, the skies caught on fire.
The air was streaked with violent flashes of lightning.
I couldn't stand this brightness, but Captain Nemo stared
straight at it, as if to inhale the spirit of the storm.
A dreadful noise filled the air, a complicated noise made up of the roar
of crashing breakers, the howl of the wind, claps of thunder.
The wind shifted to every point of the horizon, and the cyclone
left the east to return there after passing through north, west,
and south, moving in the opposite direction of revolving storms
in the southern hemisphere.
Oh, that Gulf Stream! It truly lives up to its nickname,
the Lord of Storms! All by itself it creates these fearsome
cyclones through the difference in temperature between its currents
and the superimposed layers of air.
