It looks to me like the Indians have built a fairly large "cloud rake" transmitter and were testing it when these images were taken.
I am writing this email after recently discovering the existence of your impressive research facility on Marion Island by way of QRZ.com and a host of other HAM radio websites. I was causally investigating a strange cloud formation that recently appeared above the island as reported at www.universetoday.com...
It is my understanding that your facility is staffed by meteorological researchers, so I thought I would inquire as to what your thoughts are with regards to this odd cloud formation. Might it be the product of a natural WX processes unknown to me, or might it have to do with RF operations on Marion Island? As an 802.11 wireless engineer and IT specialist, I'm quite intrigued by the later possibility.
Many thanks for reading my email and for whatever information you may soon reply with.

Indians you say?
Funny that Heliophant mentioned India too, only to retract this when he realised that india is no where near the island...
Nice try though

In mid-December 2005, the diminutive Amsterdam Island made waves—not in the Indian Ocean where it resides, but in the clouds overhead. Described casually as wave clouds, these features took on the shape of a giant ship before blending in with a larger cloud formation to the north and east.
------
The volcano’s summit, poking above the ocean surface, conspired with atmospheric conditions to make these clouds. Pushed by wind, air ascended one side of this island then descended the other. As air rises, it cools and expands, and water vapor in the air condenses to form clouds. As air falls, the clouds evaporate. If the air is uniformly humid, it will likely form a uniform layer of clouds. If the air is dry, it may produce no clouds. But if the air contains alternating moist and dry layers, clouds form only in the moist layers of air. Known as lenticular clouds, they often look like flipped-over plates. Many of these clouds strung together form larger wave patterns like the one seen here.

I wonder if... at the moment they snapped that photo --- someone five thousand feet below looked up and said...
"Hey! What's that strange sound in the sky?
You mean something like this?
(thats what your post reminded me of) Me, I have no idea.edit on 28-3-2013 by ItsEvolutionBaby because: (no reason given)

Fine, not India then but I stand by the rest of my post. Not gravity waves - no way.
A wave cloud is a cloud form created by atmospheric internal waves.
The atmospheric internal waves that form wave clouds are created as stable air flows over a raised land feature such as a mountain range, and can form either directly above or in the lee of the feature. As an air mass travels through the wave, it undergoes repeated uplift and descent. If there is enough moisture in the atmosphere, clouds will form at the cooled crests of these waves. In the descending part of the wave, those clouds will evaporate due to adiabatic heating, leading to the characteristic clouded and clear bands. The cloud base on the leeward side is higher than on the windward side, because precipitation on the windward side removes water from the air.
It is possible that simple convection from mountain summits can also form wave clouds. This occurs as the convection forces a wave or lenticular wave cloud into the more stable air above.
could make a good shot for M.Murphy's new movie 'What in the hell are they spraying'.
If these type of cloud formation is "normal" how come we don't see this type of cloud happen more often?
