   Summary Author:  Mila Zinkova;  Jim Foster

   Shown above are curious shaped,  cumulus clouds that were observed
   from near my home in San Francisco, California, on April 19, 2022. The
   spike-like features have horseshoe shapes in some cases, as shown in
   the bottom photo. Perhaps these spikes and horseshoes are caused by
    convection -- intense localized heating of the most  optically
   thick portion of cloud by the strong April sun. However, because the
   atmospheric environment where the clouds formed wasn't suitable
   ( stable atmosphere) for widespread building, they remained overall
   fairly “flat” in appearance.  Click here to see a video of these
   clouds.
