Summary
[edit]DescriptionIce Floes off the Northeastern Tip of Urup Island, Russia.jpg |
English: The north-eastern tip of the island and three small islands to the north-east are recognizable by their uniform cover of white snow and shadowing along the north-western coastlines. Sea ice that formed to the north in the Sea of Okhotsk has been piled up against the islands by prevailing north-westerly winds, forming an irregular mass connecting the islands (image centre). The orientation of patchy low clouds over Urup Island (image lower left) also suggests that north-westerly winds are present. Smaller ice floes are breaking off from the main ice mass at gaps between the islands and forming finger-like projections of ice fragments that extend to the south-east (image lower right). Surface winds may be channelled through these gaps and accelerated, hastening the breakup and movement of ice. |
