      Summary Author:  Cesar Cantu   
      Shown above is a stratus-type cloud with noticeable pouches (mammas or   
      mammatus) that I observed near Monterrey, Mexico, on July 7, 2022.   
       Mammatus clouds can appear strange and whimsical and often even   
      intimidating. Their bulging or drooping is attributable to the   
      collision of downward vertical currents that generally occurs when the   
      atmosphere is unstable, such as during thunderstorm development   
      ( cumulonimbus clouds). However, mammas can also form in  cirrus   
      and  stratus clouds, as long as there’s some downward motion   
      ( downdraft) within the cloud. The result may be a cloud base with   
      conspicuous lumps.
