Weather Theory
----------------


Toposphhere  surface to 20,000'
2 deg drops per 1000' gain


uneven heating of earth surface


North Pole  Cold

up  down   up   air movement surface flow  Less dense and rise

---Equator----  Warm


down up  down  air movement

====South Pole === cold


Equotor recieved grater amount of heat from the sun than polar regions

equator hotter less dense than cooler ... and rise towards the poles

it cools becomes denser and sinks back to the surface.



Actual barometric pressure differs based on
-altitude
- temperature
- air density


Also affects aircraft performance
takeoff
rate of climb
landings



Air flows from high pressure to low pressure

High pressure air (good Pressure)
---------------------------------
air deflects to the right - rotate clockwise
Dry
stable
decending air



Air flow into to replace rising air

Low pressure ( bad weather)
rotates counter clockwise
Unstable
- moist


Beneficial tail winds
