How would you care to “ fall ten ” half a mile above the ground ? A few sailplane pilots have figure out a manner to ride on the clouds moving over the Australian countryside , going 35 miles per hour with no power whatsoever .
These cloud are 600 miles wide , and a glider can channel-surf them just like a wave on the ocean . Here ’s how to go surfriding , half a naut mi above the ground .
“ Morning Glories ” are clouds that seem in September and October . They only demonstrate on a peninsula that starts at a good , thick 350 miles broad and is whittle down to a slender sixty - stat mi - all-encompassing strip of land surrounded by water . Here ’s how they form .
The Cape York peninsula juts directly North , and the sea breezes from both sides of it cope with in the center . The two gust of air meet over Burketown , and the hit stimulate a wave of tumultuous atmosphere that moves south-west . The air is moving through damp sea air , and the water mote in the line , impinge on by this hurry of press , often move up , over the top of the wave . Once they rise high up enough they bump off the cold of the upper atmosphere and condense , form a cloud . The wave passes , and they drop , disintegrating into unseen water - vapor again at the tail edge of the Morning Glory . The waving is n’t visible on its own . hoi polloi just see the pee droplets trance by the wave , and how they always shape at the front and dissolve at the back , showing its forward progress across the sky .
The same thing that filch the water droplets lifts aviation — and the air lifts gliders . sailplane enthusiasts get from all over the worldly concern to ‘ surf ’ the Morning Glories . The pilots employ motor to climb to cloud point in their planing machine — and then they get in front of these massive waves of mellow - pressure air , shot across the sky in seven - hundred - mile stretches .
The waves are about 1,000 feet off the ground , and form structures over 1,000 foot high . Although in the cloud things are disorderly , the tune above and around it is said to be , “ as suave as glass , ” provide both an loose drive and a potent thrust . The tumultuous tune in the swarm send through the atmosphere , shoving everything aside , provide power that can swipe gliders up to 8,000 foot . A skilled buffer can then drop , surfing across the front of the wave , do loop , or bait on the ‘ wingtip ’ of the cloud for hundreds of miles . Gliders accomplish phonograph recording speeds and soaring distances on these .
Unlike motored power , though , cloud can just disappear . When that wave of eminent - pressure air dissipates , tear up to nothing by atmospherical condition , all the melodic phrase it was pushing up falls . With a structure tug it up , the air moves in an orderly elbow room , but when it fall , it can fall in a haphazard , turbulent way that mean the glider is going to get tossed around like a plaything plane on its way towards the flat coat . Surfing air mile up in the zephyr is not without its hazards .
