Cloud streets are rows of cumulus or cumulus-type clouds aligned parallel to the low-level wind. Here, such cloud streets form rows of parallel lines over the Black Sea, seemingly connecting the land by the Strait of Kerch (above center) in the north to Turkey in the south.

Much of the land visible is coated in snow, particularly Russia (upper right quadrant) and Ukraine and the Crimean Peninsula (upper left quadrant), while the Turkish landscape below shows some snow-free areas.

Reflecting these cold, wintery weather conditions is the Sea of Azov, which appears partially ice-covered. The shallowness and low salinity of the sea make it vulnerable to freezing during winter. Formation of sea ice can occur temporarily at any time from late December to mid-March.
