Wind
streaks on the surface appear to correspnd with the prevailing winf direction
and extend downwind from topographic features. The image above shows an
example of a wind streak extending from an isolated volcano. This is most
likey to be radar-bright (rough) material exposed by the stripping away
of a regional dust cover by turbulent vortices imposed in anotherwised gently
wind by the obstructing volcano. |
