Then there's the less tangible effect that I believe is real when hitters say they simply feel more comfortable hitting in certain parks. Maybe a particular park has a more symmetrical outfield with an especially clear batter's eye.

Some places also play more night games than others when batters theoretically should have an easier time picking up the baseball.
All of this affects distance though. The very definition of a homeurn is hitting the ball a specified distance in the air.

And when you look at distances, it shows that the effects you mentioned are inconsistent. Houston is one of the warmest climates in baseball and there's supposedly a jetstream effect at Yankee Stadium.

Minute Maid Park and Yankee Stadium have the two lowest average homerun distances in the majors, so these effects exist in these stadiums, they must be on the DL.

Of course the Astros do suck which might skew that number.
