First, a reserve of heat beneath the sky,
and the water a sea releases
into the scorching air of summer.
From the west comes a cooler breath.
Between the two, the air tightens.
Something changes.
The wind below does not speak
the language of the wind above.
Between them, almost invisible,
the rotation begins.
In the heart of the storm,
a mesocyclone forms.
On the radar screen,
a hook appears.
Heat, moisture, cold, rotation:
the supercell tightens,
the rotation descends,
and suddenly a column reaches the ground.
Nothing announced it as a certainty.
The meteorologists saw the threat
in the equations, measured the instability,
knew the conditions were in place —
but no one knew
how powerful the vortex would become.
Science knows the laws.
It knows the heat that feeds it,
the moisture that charges the air,
the wind that sets the air turning.
It can recognise the conditions.
It does not know
when the phenomenon will take shape,
nor what exact form it will take.
The sky is not magic.
It obeys.
And for a few minutes,
rotation becomes a column,
the column reaches the ground.
The instruments continue recording.
The pressure falls.
The wind increases.
The figures are entered.
What they measure is exact.
But what has just passed
is not contained in the measurement.
