We have crossed the equator! I still have my hair (the ceremony is
sometime this week but we won’t know when until it’s too late to run) and
the fish are still flying. Birds have now joined us as well, boobies
they’re called, that soar above the ocean, watching the fish and then, in
the blink of an eye, turn upside down and sky rocket downwards into the
ocean. In, deep in, maybe a metre or so, grab a fish and bounce out again.
It’s incredible to watch. The concentration, the energy… if only we could
apply that to our daily activities!
As much as I love staring at infinity,
it’s nice to have some activity happening in the foreground as well, it
keeps you alert I guess. Soaring, soaring, flying with the ship, flying at
10 knots. Mindboggling. No, not the birds speed, but ours. Our slow speed.
You can ride a bike at 10 miles an hour can’t you? OK, I know it’s nautical
miles but still, not far off. I am travelling around the circumference of
the Earth at ten miles and hour. From Britain to Antarctica. Ten miles an
hour! Doesn’t anyone else find that utterly bizarre? That we get there at
all, let alone in as little as two months.
A common reaction when I left was, ‘two months on a ship?! That’s crazy”.
We are so time oriented. On the ship, it doesn’t feel long at all. It
feels, appropriate, I guess. I mean, it’s a long way we’re going and we’re
on a not-massive ship with an awful lot of Stuff on it. And we keep going.
Ten miles an hour maybe but no traffic lights, roundabouts, jams,
meetings. this is way beyond commuting, or even going for a Sunday
One of the most remarkable things for me has been to watch the world go by,
underneath us, past us, as it were. The weather hasn’t improved, we’ve moved
into better weather. We are the ones doing the moving. Leaving Immingham, cold
and dreary, the first few days were cold, windy and wet. Then, in the Bay of
Biscay, they were rough. Rough Seas. It’s all about ocean circulation and wind
systems and how they all meet and create this amazing chaotic regime right there.
And there we were, right there, feeling the chaos in our stomachs. Somehow,
the energy circulating around our bodies at that time, unpleasant as it was,
had been sourced from the sun and the sea and the turning of the earth. I am
sailing through a meteorology text book.
After the Bay of Biscay, we moved into calmer seas, warmer, gentler wind,
past the Meditterranean, the Canaries, the east coast of Africa. It wasn’t
sweltering, it was perfect. The mid-latitudes. Of course! Then, as we sail
further south the air has become hotter, the direct rays from the sun more
intense and the weather, stormier again. Nothing like the Bay of Biscay but
we’re definitely rocking and afternoons have sen some ominous dark clouds.
We must be near the equator!
I hadn’t thought if it before, I’m desperate for my old notes on earth
weather systems, but it makes sense, in my very amateur perception of
what’s going on. Imagine the earth, a round ball, with the sun above the
equator. For now, neither are moving. Hot air at the equator rises and
travels to cooler areas, the higher latitudes, towards the poles. So you
have air rising from the middle and the separating, like a T-junction, at
around cloud-height, some going south, some going north. This happens to
air all around the Earth. From the side, two donuts: air rising at the
equator, travelling high up towards the pole, sinking when it’s no longer
less dense than the surrounding air, and travelling back along the surface
of the earth, this now-cold air seeking warmer climes. At the equator,
therefore, you have winds from the south and the north converging and
rising together, starting the whole circulation system again.
Now, add spin. Make the Earth spin. All that air that is moving up, out
high, down and back low, is trapped within the spinning earth -system but
not fixed to the earth. It creates a circulation system of its own in
response to the spinning of the world. Like the ripples that happen in
water when you skim stones. The combined effect of air flowing from the
poles to the equator at the surface, and the spinning of the earth, makes
the trade winds. At the equator, hot, damp air flowing from both poles
meets and rises upwards. So there’s your low pressure zone. As the air
rises, it cools, water vapour condenses and clouds form. The waterless air
then continues its way, high up, back towards the poles. Round and round
and round and round. It’s amazing. And that’s not even mentioning what’s
going on in the oceans. The more you think about it, the more you realise
how great, and complex, this place is, this Earth. And I’m honoured to be
travelling around it, learning from it, at ten miles an hour.
