Earth's
atmosphere consists of 78% nitrogen, 21% oxygen and 1% argon.
The weight of one cubic foot of air molecules increases as barometric
pressure increases and decreases as temperature increases. The
more one cubic foot of air molecules weigh, the more air molecules
are present.
a. Weight
of One Cubic Foot of Air Molecules Formula
Wt = (1.325)
x (B) / (T) + (459.2)
where:
1. Wt stands for weight
2. B stands for barometric pressure
3. T stands for temperature
b. Barometric
Pressure
At
sea level, all of Earth's atmospheric total height pushes downward.
All of Earth's atmospheric total height pushing down increases
barometric pressures. High barometric pressures mean high air
molecule densities. High air molecule densities mean high air
molecule weight per cubic foot. Consequently, sea level cities
have high barometric pressures.
At
high altitudes, less than all of Earth's atmospheric total height
pushes downward. Less than all of Earth's atmospheric total height
pushing down decreases barometric pressure. Low barometric pressures
mean low air molecule densities. Low air molecule densities mean
low air molecule weight per cubic foot. Consequently, high altitude
cities have lower barometric pressures.
c. Temperature
High
temperatures mean low air molecule densities. Low air molecule
densities mean low air molecule weight per cubic foot. Consequently,
high temperature cities have low air molecule densities. Low
temperatures mean high air molecule densities. High air molecule
densities mean high air molecule weight per cubic foot. Consequently,
low temperature cities have high air molecule densities.
d. Pitching
Implications
High
air molecule densities significantly decelerate fastballs. High
air molecule densities significantly increase the direction changes
of breaking pitches, such as curves. Because high barometric
pressures increase air molecule densities, breaking ball pitchers
should pitch in high barometric pressure areas. Because low temperatures
increase air molecule densities, breaking ball pitchers should
pitch in cold weather. Therefore, breaking ball pitchers thrive
at cold, sea level cities.
Low air molecule densities do no significantly decelerate fastballs.
Low
air molecule densities do not significantly increase the direction
changes of breaking pitches, such as curves. Because low barometric
pressures decrease air molecule densities, fastball pitchers
should pitch in low barometric pressure area. Because high temperatures
decrease air molecule densities, fastball pitchers should pitch
in hot weather. Therefore, fastball pitchers thrive at hot, high
altitude cities.
