 Kelvin-Helmholtz Clouds Over Albuquerque, New Mexico

   Shown above are  Kelvin-Helmholtz clouds that I photographed while
   at a stoplight in Albuquerque, New Mexico on November 12, 2020. They
   reminded me of  ocean waves or a  DNA strand. Sometimes called
    fluctus or billow clouds, they result from  Kelvin-Helmholtz
   instabilities -- air in the layer containing the clouds is moving in a
    different direction and at a slower speed than the air in the layer
   just above the clouds. Though not uncommon, Kelvin-Helmholtz clouds
   usually only capture our attention when they're rather conspicuous, as
   they were on this mid-autumn day.
