Atmosphere Gas – Nitrogen (most abundant), oxygen, / carbon dioxide – has the ability to absorb heat radiated by earth, water vapor

Atmosphere Pressure is in MB –
Atmosphere pressure in the PPI –
Atmosphere pressure at sea level – slightly more 1000 millibars, pressure decrease with altitude
3.5 miles 50% atmosphere is below
10 miles 90% atmosphere is below
Atmospheric carbon dioxide is transparent to incoming Short-Wavelength solar radiation. But it is not transparent to some of the Long –Wavelength outgoing terrestrial radiation.

Ozone –combines 3 atom oxygen (03) / concentrate between 10-50 kilometers above the stratosphere / absorbs harmful ultraviolet radiation

Thermosphere – upper limit -
Mesosphere – temperature decreases -
Stratosphere – above the troposphere – temperature increases at top
Troposphere – lowermost layer - all important weather phenomena occur - temperature decreases with altitude
*** - There is pause in between each

Equinoxes – occur midway between the solstice - length day equal night - Sept 22-23 march 21-22(spring)
Sun angles – near water climate = cool summer, warmer winter
Northern hemisphere – June 21-22 (summer) – December 21-22 (winter)

Heat transferred in our Earth System -Conduction – transfer of heat through matter by molecular activity
Convection – transfer of heat by the movement of al mass or substance for on place to another
Radiation – transfer of heat by electromagnetic waves

Climate – Air Mass –
Equatorial low – rising air – abundant precipitation
Subtropical high – stable - dry air
SubPolar low – warm and cold winds interact – polar front – area of storms
Polar high – cold, subsiding air

Leeward side of the mountains – usually deficient in moisture


Clouds - Cirrus – high, white, thin wispy fibers/ Cumulus – globular, individual cloud masses/ Stratus – sheets or l...
