I
t looked like something out of
The X-Files, a big hole that had
opened up in the clouds over
Shepton Mallet, Somerset, on
Monday (News, December 2).
This unearthly sight was a fallstreak
hole, also called a hole-punch cloud.
One case in Russia, in October
2009, caused headlines such as
“UFO hovers over Moscow”. But
fear not, these holes are simply
made by aircraft climbing up or
descending through a layer of cloud.
The clouds consist of supercooled
water droplets at about minus 15C,
but they remain liquid. As an
aircraft flies through the cloud, it
makes the air expand and cool, and
the cloud’s water droplets freeze into
tiny ice particles that tumble out of
the cloud leaving a large hole
behind. This explains why a hole in
the clouds is most likely to crop up
on flight paths near airports, where
aircraft are climbing upwards or
descending to land.
In some cases the ice crystals
tumbling out can be seen as delicate
white streaks falling from the hole,
hence the name fallstreak holes.
The falling ice can also create a
burst of rain or snow on the ground,
depending on the air temperature
below the cloud. In a study in 2011, a
fallstreak hole near Denver airport
in Colorado spread a narrow path of
thick snow on the ground roughly
20 miles long and 2.5 miles wide.
These clouds can often occur in
Britain and other parts of western
Europe, where supercooled clouds
are quite common.
An enchanting sight also appeared
on Tuesday over parts of England, as
small patches of high-altitude clouds
lined up in parallel rows, looking
like the ripples on a sandy beach
after the tide has gone out. This was
cirrocumulus undulatus, a beautiful
and fairly unusual cloud, its
stunning pattern driven by strong
winds blowing at different heights in
the atmosphere, with the rows of the
cloud lined up perpendicular to the
wind direction.
However, it’s best to watch out if
cirrocumulus appears in the western
sky because it is often a sign that
bad weather is on the way in the
next 15 to 36 hours.
