Air and Climatology<br />
Introduction<br />
Climatology reflects a component <strong>of</strong> our ecosystem whose operating mechanisms are complex and impacts are<br />
pr<strong>of</strong>ound. Wea<strong>the</strong>r’s expressions includes precipitation <strong>of</strong> all <strong>for</strong>ms, temperature, and wind. Geography, terrain,<br />
vegetation, natural and human-derived chemical constituents are some <strong>of</strong> <strong>the</strong> principal participants. These, in<br />
turn, affect air and water quality, flooding, droughts, flora and fauna and even human vitality.<br />
The Atmosphere<br />
As we continue our exploration from <strong>the</strong> crust <strong>of</strong> <strong>the</strong> earth upward, we find an heterogeneous atmosphere.<br />
Distinct "layers" have specific characteristics. We begin with <strong>the</strong> troposphere wherein wea<strong>the</strong>r is <strong>for</strong>med. It<br />
serves as insulation <strong>for</strong> some <strong>of</strong> <strong>the</strong> sun's captured energy as it radiates to and rebounds from <strong>the</strong> oceans and land.<br />
With increasing elevation is a concurrent decrease in temperature. The upper extent <strong>of</strong> <strong>the</strong> troposphere, or<br />
tropopause, is so cold as to cause migrating water vapor to condense or freeze, preventing fur<strong>the</strong>r ascension<br />
through <strong>the</strong> higher spheres. Next we proceed through <strong>the</strong> stratosphere where temperatures begin to climb due<br />
to ozone production. Passing through <strong>the</strong> stratopause, we arrive at <strong>the</strong> mesophere which reverts to an ascending<br />
cooling pattern. As we exit via <strong>the</strong> mesopause, we reach <strong>the</strong> outlying <strong>the</strong>rmosphere.<br />
Wea<strong>the</strong>r<br />
Wea<strong>the</strong>r is driven by many factors, interacting on a global scale. In essence, our atmosphere is sectioned into<br />
convection cells. These units contain perpetually cycling currents <strong>of</strong> air. The sun's energy, serving as <strong>the</strong> primary<br />
mobilizer behind atmospheric circulation, provides intense solar radiation at <strong>the</strong> equator. The warmed air which<br />
is less dense rises, spreads out and sinks with cooler air moving in from <strong>the</strong> poles.<br />
This model <strong>of</strong> circulation receives continual influences, both globally and locally. The earth's rotation effects an<br />
