With a quick glimpse of the naked eye, clouds don’t appear to move much, but with time lapse photography one can really see the rising and sinking motions within the troposphere (the lowest layer of the atmosphere where weather occurs). Images of these towering cumulus clouds were captured every three seconds over a span of several minutes to build these time lapse sequences (Imagery by meteorologist Todd Shoemake). Towering cumulus clouds occur when sufficient moisture, lift and instability are
