Weather and wind on a planet with a dense atmosphere

I've been building a world that has a thicker atmosphere than that of Earth, about half the gravity, and twice the amount of oxygen. My reasoning behind these features is mainly to support the growth of large trees and megafauna, and to make it easier for my races of intelligent bats to fly.

Now, one thing I haven't been able to figure out about this world it how these changes, particularly the dense atmosphere, would affect the planet's weather.

For example, I've been thinking that because the atmosphere is thicker, the wind on this planet would put more force on anything it's hitting. The thick atmosphere could trap more heat and make more violent storms, if it doesn't just homogenize the planet's temperature.

Basically, I think this planet would either have extreme weather, or very little weather. But I don't know which.

Therefor, my question: Given the above parameters, what could air circulation and wind speed be like compared to Earth?
