Images

It took the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite a full five minutes to fly over this expansive cloud pattern on April 29, 2009.

The sprawling “S”-shaped swirl is actually two cyclones that seem to be feeding on each other.

Polar cyclones often form as a result of low-pressure systems over the ocean, and usually bring winds and heavy snow. MODIS acquired this photo-like image over the cold waters of the South Atlantic Ocean, where winter is approaching. The spot of green in the upper right corner of the image is coastal water off the southern tip of Africa.
