Face in the clouds
Last August in New Brunswick , Canada , YouTube user " denisfarmer " shoot a video of what may be themost convincing " face in the cloud " ever . As a tempest front moved across the sky , a adult male ’s visibility seemedto egress .
Totally tubular
In February , a uncommon and beautiful " whorl cloud " was photographed down in the sky above the AtlanticOcean near Brazil . bowl cloud are often carry out of a storm ’s downdraft . Sinking cold air cause lovesome , moist aviation near the sea ’s Earth’s surface to arise , and when the airwave attain higher altitudes , the moisture in itcondenses to form a swarm . air current from the tempest then roll the cloud into a subway .
Heavenly halo
UFO worshipper took a strong stake in this strange cloud formation when it seem over Moscow in2009 . But meteorologists identified the ring of lightness as an optical effect due to sun hitting whatis known as a cakehole punch swarm . These appear as a circular or ellipse hole in a thin stratum of air containingsupercooled piss droplet . When a section of the level is disturbed , such as by wind or a jet planepassing through it , the droplet can stop dead directly or evaporate , give behind a pickle .
Top hat in the sky
A swarm shaped like a top lid forge over Mount Fuji , Japan on June 21 . Such formations , calledlenticular cloud , typically hap when moist air flow over a passel and condenses .
Riding a volcano
Astronauts on board theInternational Space Stationtook this awesome photo of Sarychev volcano in Russia ’s Kuril Islands just at it start to erupt in 2009 . The photo also get some rather strange atmospherical activeness at the top of theash plumage . accord toNASA , the smooth livid swarm atop the smartly rising feather may be water abridgment that resulted from speedy rising andcooling of the air volume above the ash editorial , and is likely a transient feature . As for the surroundingatmosphere , it has been thrust outward by the jolt wave from the clap .
Sky tsunamis
A series of immense break waves lined the skyline in Birmingham , Ala. , last December , but they werein the sky , not the ocean . The incredible cloud formations were pristine examples of " Kelvin - Helmholtzwaves , " which evolve when a fast - moving bed of liquid slides on top of a slower , thicker layer , draggingits open and cause crests of the duncical layer to shift forward .

Don’t mess with Texas
This baleful cloud shaping is the most severe character of electric storm : a supercell . It developed in Mayin the Texas panhandle , and gave rise to at least one twister . " What you are seeing here is a well - developedrotating supercell thunderstorm , and the condensation design at cloud base forms a ' belt ' or ' wall’appearance as air is lift and blow into the swirling violent storm , " say Chris Walcek , a meteorologist at theAtmospheric Sciences Research Center at the State University of New York , Albany .
Cloud lumps
These " mammatus cloud " were photographed in the city of Regina , Saskatchewan , in June 2012 , follow a severe tempest warning and tornado catch . Although their organisation is not completely sympathise , these rare clouds usually develop at the groundwork of a thunderstorm , and appear chunky because of instability and temperature differences between sink and rising zephyr .
