Weather and Climate
| Question | Answer |
|---|---|
| Insolation | Incoming solar energy |
| Earth’s albedo | ~30% |
| % absorbed by Earth | ~70% |
| Albedo definition | % reflected |
| High albedo | More reflection |
| Low albedo | More absorbtion |
| Atmosphere absorbs | ~20% |
| Surface absorbs | ~50% |
| Earth must balance | Energy in/out |
| Outgoing radiation type | Longwave |
| Incoming radiation type | Shortwave |
| Greenhouse effect | Traps Hear |
| Wind | Moving Air |
| Wind caused by | Pressure differences |
| Wind moves | High → Low |
| Isobars | Equal pressure lines |
| Close isobars | Strong wind |
| Wide isobars | Weak wind |
| Pressure gradient | Pressure Change |
| Strong gradient | Fast wind |
| Weak gradient | Slow wind |
| Pressure gradient force | Starts wind |
| Coriolis cause | Earth rotation |
| Northern Hemisphere | Deflect right |
| Southern Hemisphere | Deflect left |
| Coriolis at equator | none |
| Coriolis at poles | Strong |
| Faster motion = Coriolis | Stronger |
| Gravity role | Balances pressure |
| Friction effect | Slow wind |
| Friction strongest where | Surface |
| Water heat capacity | High |
| Latent heat | Phase change energy |
| Sensible heat | temp change |
| Tropics receive | More energy |
| Polar receive | Less energy |
| Air mass | Same pressure/moisture |
| Front | Air boundary |
| Cold front | Cold Pushes up |
| Warm front | Warm risees |
