      The breathtaking photos of the sky shown above were captured during my   
      morning walk in Hong Kong, on March 30, 2022. At the time, I was on a   
      hillside (Ho Man Tin) near the center of the city. These are   
       asperitas clouds, which on occasion can be observed in the hours   
      following the passage of potent storms. They take shape when air cooled   
      by the  sublimation of  ice crystals protrudes through an   
      existing cloud base. Strong  wind shear creates the wavy patterns,   
      referred to as undulatus. How wonderful it was to see such a  sky,   
      which to me resembled upside-down waves.
