Wind? what wind? Theres no air on mars how can you have wind without air?
Mars has a very thin atmosphere, but thick enough for there to be winds and dust storms. As 'Drunkenparrot' mentioned above, Mars is well known for having huge dust storms that can cover large areas of the planet. It is also known to have "dust devils", which are almost like tiny tornadoes (just like "dust devils" seen on Earth).
Here is a link describing the dust devils that were photographed by the rover "Spirit" several years ago in Gusev Crater:
Dust Devils at Gusev
and a youtube video:
Here is another story about the dust devils:
Research Helps Scientists Better Understand Dust Devils on Mars and Earth
...and a story about a picture of alarge-scale dust storm on Mars, taken by the orbiting Mars Reconnaissance Orbiter (MRO):
MRO: Mars Storm Chaser
Here is an article (and pictures) of a HUGE global dust storm that covered most of Mars back in 2001:
The Perfect Dust Storm Strikes Mars
By the way, Mars also has clouds.
Here is an article (with a video) of clouds near Mars' North Pole, taken by NASA's "Phoenix" lander. The video in this article is time-lapse (it has been sped up):
Martian Clouds Above the Phoenix lander
Here is a video of clouds moving in Mars' atmosphere, also taken by NASA's "Phoenix" lander (this video is also time-lapse, showing about ten minutes of cloud movement in three seconds):
