It's hard to believe that I didn't notice this a long time ago, but I discovered today that my bike directly controls the speed of the wind.
It actually isn't the bike, just the rear shifter. Although the wind was pretty strong to begin with, it never gusted until I shifted into a higher gear. Anytime I shifted up the wind would pick up immediately, while shifting down would have the opposite effect. I found the phenomenon very curious.
I will continue my research as the month progresses and report back with any further observations. Stay tuned.
