April 11, 2009 - Cloud Streets in the Barents Sea
Tweet
Today's image, captured by the MODIS on the Terra satellite on April 5, 2009 shows unusual cloud formations over the Barents Sea. The Barents Sea is north of Scandanavia and Russia and part of the Arctic Ocean. At the bottom of the image you can see Russia (right), Finland (west of Russia), Sweden (west of Finland), and Norway (to the north of Finland and Sweden).
The lines of clouds are called "cloud streets." These are caused when
low-level winds moving between and over obstacles cause the clouds to
line up into rows (much like streets) that match the direction of the
winds. At the point where the clouds first form streets, they're very
narrow and well-defined. But as they age, they lose their definition,
and begin to spread out and rejoin each other into a larger cloud
mass.
