Review for Meteorology Unit Test
| Question | Answer |
|---|---|
| Wind Vane | Measures wind direction |
| Thermometer | Measures temperature |
| Barometer | Measures pressure |
| Anemometer | Measures wind speed |
| Source of energy for Earth | Insolation (incoming solar radiation) Sunlight |
| Convert 1023.7 mb pressure for a station model | 237 |
| Winds are caused by | pressure differences and heating of Earth's surface |
| Earth's polar ice caps (glaciers) are melting due to | increase in greenhouse gases (CO2 and methane) |
| Conduction | Heat transfer through TOUCH |
| Radiation | Heat transfer through WAVES in the air |
| Convection | Heat transfer through density differences |
| Low Pressure characteristics | Warm, Wet, toward, counterclockwise |
| High Pressure characteristics | Cold, dry, away, clockwise |
| Isobars (lines connecting points of equal pressure on a weather map) close together means | High wind speeds (velocity) |

| cA Air Mass | Continental (dry) Arctic (very cold) Northern Canada |
| cT Air Mass | Continental (dry) Tropical (warm) Arizona |
| mP Air Mass | Maritime (wet) Polar (cold) Northern Atlantic or Pacific |
| mT Air Mass | Maritime (wet) Tropical (warm) Gulf of Mexico |
| Weather moves toward what direction in the USA | Northeast (Maine) |
| Ozone | Protects Earth from harmful ultraviolet radiation |
| Gases in Earth's troposphere (atmosphere) | 78% nitrogen 21% oxygen 1% other |
| Hydrosphere covers ________% of Earth's surface | 72% |
| Cold fronts | Move quicker Warm air forced up |
| Conditions needed for lake effect snow | Warm lake water cP (cold dry) air mass flows over the lake |
| Psychrometer | Measures relative humidity and dew point |
| Dewpoint | The temperature that the air must cool to in order to get precipitation |
| With fronts, the characteristics (warm or cold air) are seen _________ or the the _______ of the front boundary on a weather map | Behind or to the left |
