Well during the long plutonian winter(about 160 years), there would hardly be any air at all, because the methane and nitrogen in Pluto's atmosphere freeze solid onto the surface when the planet experiences temperatures as low as -410 degrees F.
When Pluto reaches it's perihelion and is closer to the Sun, then the atmosphere sublimates(becomes a gas), and creates an atmosphere around Pluto. It is still frigid (-350 degrees F), but there is air, and mostly likely wind, but not very strong, because their is not enough heat to create temperature imbalances. It is possible that because the pressure of the gas returning to the air, turbulence would be created.
So therefore, Pluto has a seasonal atmosphere, though even in the summer it is extremely thin, and unbreathable, not to mention dreadfully cold, and relatively dark, as Pluto is so far from the Sun.
Hope this helps
