Above the scenic cityscapes of Cape Town in
South Africa -
something odd is happening in the skies.
As the clouds gather pace, panic ensues, and
people take to social media to vent their
fear.
There's talk of tornadoes, UFOs and even aliens.
But returning back to earth for a moment - meteorologists
are calling them Lenticular clouds.
These are lens-shaped and typically stationary.
They form when air flows along the surface
of the earth and reaches some sort of obstruction
point, like a mountain.
That then diverts the flow of moving air -
and because the air flow contains moist air
within it,
a serious of large-scale standing waves can
develop.
Then the alien-like shapes take form.
And when the moist air flows back down to
the back of the wave, the clouds eventually
evaporate and vanish.
So next time you're witnesses to a spectacle
of the skies -
it may be worth getting your phone out, to
record any UNUSUAL movements.
