Title: Earth Limb and Clouds over Open Ocean, Location Unknown
Description:
A northern hemisphere tropical storm over open ocean - location unknown,
can   be seen forming by the loosly defined cyclonic spiral gyre within the 
cumulonimbus clouds.  The storm can be readily identified as being in the 
northern hemisphere by the counter-clockwise rotation of the gyre.  Because 
of the Earth's rotation induced coriolis effect, all northern hemisphere 
cyclonic circulations rotate in a counter-clockwise spiral and all those in 
the southern hemisphere rotate in a clockwise spiral.
