English: Frigid air blowing from Eastern Russian created dramatic cloud formations over the Sea of Okhotsk in late November, 2017. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite acquired a true-color image of the stunning scene on November 25. Snow covers the land of Eastern Russia in the west of this image, with a large bank of cloud overlying the land in the northwest. Long parallel rows of cumulus clouds blow off the snow-covered area and over the blue waters of the Sea of Okhotsk. These rows of cloud, known as “cloud streets” form as cold, dry air from the land blows across relatively warmer, much moister ocean water and create cylinders of spinning air. Where the air is rising, small clouds form. Where the air is descending, the skies are clear. The cloud streets align along the direction of the wind movement.
