Explanation:
Is that a cloud or an alien spaceship?    
   
It's an unusual and sometimes dangerous type of thunderstorm cloud called a    
supercell.   
   
Supercells may spawn damaging    
tornados,    
hail,    
downbursts of air, or    
drenching rain.    
   
Or they may just  look  impressive.   
   
A supercell    
harbors a    
mesocyclone --    
a rising column of air surrounded by drafts of falling air.    
   
Supercells    
could occur over many places on Earth but are particularly common in     
Tornado Alley of the USA.   
   
Featured here    
are four time-lapse sequences of a    
supercell    
in 2013 rotating above and moving across    
Booker,    
Texas.    
   
Captured in the video are new clouds forming near the    
storm center,    
dust swirling on the ground,    
lightning flashing in the upper clouds,    
all while the impressively    
sculptured complex rotates ominously.    
   
Finally, after a few hours, as shown in the final sequence, dense    
rain falls as the storm begins to die out.
