In the early 2000s,
several Spanish scientists became interested in relatively unknown and
mysterious meteorological phenomena known as megacryometeors
after huge chunks of ice, some weighing up to 6 pounds (2.7 kg), fell
repeatedly from cloudless skies over Spain. While a few peer-reviewed
studies were published following these incidents , little remains known about these anomalous ice conglomerations.
Ice falling from passing aircraft is
often cited as the most likely explanation for megacryometeors, as ice
can form on aircraft at high altitudes and melt as aircraft descend.
However, numerous incidences of megacryometeors have been cited far from
flight paths, not to mention the fact that accounts of the phenomena
pre-date the invention of aviation.
A Spanish megacryometeor from 2007.
The latest report of an anomalous ball of ice falling from the sky occurred in Arizona on April 27 as a 10-pound chunk of ice crashed through a woman’s house
in Havasu, Arizona. Unlucky homeowner Sandy Ford said the
megacryometeor crashed through her roof and destroyed her garage ceiling
before exploding on the ground. The ice was clear, as opposed to the
blue ice that is typically used in airline septic systems. According to Ford, the noise of the ice exploding in garage was so loud that neighbors called emergency services:
It sounded like a sonic
boom in my garage. My neighbor heard the sound and came over, then
someone from the fire department showed up. When I went out, I was
expecting to see that my hot water heater exploded … it was a chunk of
ice that fell through the tile roof, through the ceiling and all the way
to the ground.
In 2018, a megacryometeor was caught on camera as it exploded on a London street just feet away from a street cleaner. Just last month, a huge chunk of ice shattered a Colorado woman’s windshield as she drive along a busy highway. When will one of these incidents turn deadly?
For now, megacryometeors remain an
enigma. Could these phenomena merely be signs that aviation and human
population growth are contributing to increased incidents of ice falling
from aircraft onto populated areas? Then what to make of similar
reports that are nowhere near flight paths? Aircraft could be to blame,
but that would mean that – gasp! – there are undisclosed aircraft buzzing around places they shouldn’t be. That couldn’t be, could it?
But that leaves out what to make of
reports that pre-date aircraft. Could these megacryometeors simply be
some kind of super-sized hailstone created under a very specific set of
atmospheric conditions? That begs the question: could they become more
common as climate patterns change? That’s a scary thought.
