Definition
SW and LW is absorbed more at lower latitudes near the equater than higher ones near the poles
|
|
|
Term
|
Definition
near the equater they absorb more SW than they emit LW which makes their net radiatio nhigher making it hotter in buffalo there is less SW than LW making it colder....
Net radiation is higher near the equator |
|
|
Term
|
Definition
| There is ahigher angle of incidence is lower where at the poles they are 90 degrees as you move farther north or south insolation decreases |
|
|
Term
| Where is LW radiation greatest? |
|
Definition
| It is greatest at the low latitutes because warmer object emit more radiation than colder ones.. since lower absorbs more SW then the LW beign radiated is mor because it is warmer |
|
|
Term
| how can high latitudes radiate more? |
|
Definition
radaiton imbalances causes things to move creatign wind and ocean currents.. they carry warmth from low lattitudes to high and vice versa
Wind tranfers 50 %
evaporation and percipitation 30 %
Ocean Currents 20% |

Term
|
Definition
| This creates a balance in the earth otherwise cold areas would get progressivley colder and hotter would get progressivley hotter |
|
|
Term
|
Definition
| hot air rises creating a surface low pressure that high elvation air cools and spreads to the north |
|
|
Term
|
Definition
| high elevation air spread out above equator sinks downa t around 30d latitude this then spreads to the polar regions |
|
|
Term
|
Definition
| Cold air sinks, high pressure, and heads to the sub polar low |
|
|
Term
|
Definition
| air from subtropic high and polar converge here |
|
|
Term
| Pressure zones are connected by 3 winds |
|
Definition
Trade winds: Sub tropic high to equator
Westerlies winds: sub tropic high to sub polar lows
Polar easterlies:winds form poles meet westerliescreating polar fronts, coriolis effect pole winds carry heat to poles and equatorward carrys cool to EQ |

Term
| what portion of water is moved by winds? |
|
Definition
200 meters
deep water follows its own current but surface water follows similar current as wind currents |
|
|
Term
| ocean currents are curved for 3 reasons |
|
Definition
winds are curved
coriolis affect turns it 45 degrees
deflected when they hit land |
|
|
Term
|
Definition
| Circular currents moving under the subtropic highs |
|
|
Term
| direction and temperature of currents |
|
Definition
| Cool currents move awar from high latitude and warm currents move away from low atitudes |
|
|
Term
| Example that proves these currents |
|
Definition
| rubber duckie massacre of 1995 whena rig spille rubber duckies and they ended up all over different coast followin the wind pattern or the message in a bottle |
