      On March 23, 2023, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Terra satellite captured a true-color image of   
      a spectacular cloud formation above the Labrador Sea.   
      
      The Labrador Sea is flanked by Canada’s Labrador Peninsula in the   
      southwest and Greenland in the northeast. It is part of the North   
      Atlantic Ocean and connects to the Arctic Ocean via various straits and   
      bays to the north. Springtime brings big changes to the region, as fast   
      ice—ice which clings to shore—and floating sea ice begin to melt as   
      daylight lengthens. Despite warming air temperature, strong winds often   
      blow from the north, carrying bitterly frigid air. Both the melting ice   
      and frigid air can create beautiful patterns when viewed from space.   
      
      In this image, the sheets of fast ice clinging to the Labrador   
      Peninsula are edged with delicate filigrees. These delicate patterns   
      are created by the interaction of thin ice floating over moving   
      currents and waves.   
      
      The predominant pattern, however, is the long, parallel bands of white   
      that stretch across the Labrador Sea. Called “cloud streets”, this type   
      of cumulus cloud is common during the spring, when cold, dry air blows   
      over comparatively warmer water. The clouds form at the top of parallel   
      cylinders of rotating air, created by rising warm, moist air. On the   
      upward side of the cylinders (rising air), water vapor condenses and   
      forms clouds. Along the downward side (descending air), skies remain   
      clear. The streets form along the direction of the prevailing wind.
