Stormy conditions charted over the North Pole

A plot created by using ice concentration, acquired on 25 August 2006 by the EOS Aqua satellite's AMSR-E instrument (light blue arrows), and ice drift from Envisat's ASAR Global Monitoring Mode data (dark blue arrows), showing the effect stormy conditions have on ice. The ice in the red circle is divergent as a consequence of a low pressure system centred on the North Pole.
