      A blast of frigid air blew over Hudson Bay in early November 2022,   
      creating stunningly beautiful patterns in the cloud. The Moderate   
      Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua   
      satellite acquired a true-color image of snow-laden Nunavut, Canada and   
      cloud streets stretching over Hudson Bay on November 1.   
      
      Cloud streets—long parallel bands of cumulus clouds—form when cold air   
      blows over warmer waters, while a warmer air layer (or temperature   
      inversion) rests over the top of both. The comparatively warm water   
      gives up heat and moisture to the cold air above, and columns of heated   
      air called thermals naturally rise through the atmosphere. The   
      temperature inversion acts like a lid. When the rising thermals hit it,   
      they roll over and loop back on themselves, creating parallel cylinders   
      of rotating air. As this happens, the moisture in the warm air cools   
      and condenses into flat-bottomed, fluffy-topped cumulus clouds that   
      line up parallel to the prevailing wind.   
      
      Temperatures in Rankin Inlet, Nunavut have been on a winter-like   
      chilling trend, with highs of 1˚F (-17.2˚C) and lows of -5˚F (-20.6˚C)   
      registered on November 2. Additional snow along with frigid   
      temperatures is on the forecast for the upcoming weekend.
