These wispy rows of cloud or “cloud lanes” are recognized as a “landmark” by successive shuttle crews. This unique cloud formation off Oman is virtually constant at certain times of the year. The clouds are created by a small vortex in the low-level wind current. There is little difference between the ocean and atmosphere temperatures here, but the air current may have been subjected to heating from the Somali Current.
