With an opening weekend at Alex Box Stadium-Skip Bertman Field baseball is in full swing. Weatherwise Magazine provided an interesting article noting the effects of weather on a baseball. For example the low air density and the usually low humidity contributed to one of the highest home run rates in the Major Leagues after the Colorado Rockies came to Denver in 1993. To mitigate the rate, since 2002, baseballs for the Rockies home games are kept in a humidity-controlled room at 50% RH. This process actually "deadens" the ball. Temperature has an even greater impact on the density of the atmosphere and the ball flight than humidity. On a 90-degree day the flight of a baseball causes extra curve ball break.
