| A | B |
|---|
| Ozone | blocks UV radiuation |
| High Wind | from steep air pressure gradient |
| nitrogen | most abundent gas |
| stable air mass | no vertical air movement or storms |
| convergent air flow | low pressure and lifting air |
| divergent air flow | high pressure and subsiding air |
| frontal wedging | warm air moves up over colder air |
| orographic lifting | air flow move upward when it hits a mountain |
| Clouds keep the temperature | cooler in the day time and warmer at night |
| 2 most important green house gases | Water vapor and Carbon Dioxide |
| Ocean currents | moderate temperature on adjacent land |
| Increasing elevation causes | decreasing temperature and more precipitation |
| Troposphere | where weather happens |
| relative humidity | Amount of water in air / amount of water air can hold |
| Water in the atmosphere | 0 - 4% |
| The cause of global warming | increased carbon dioxide in air |
| Carbon Dioxide comes from | burnig fossil fuels, volcanoes, organisms |
| Water Vapor comes from | evaporation from oceans |
| greenhouse gases | absorb Earth's radient enerrgy |
| Koppen Climate for most of NC | humid subtropical |
| Koppen climate | classifies by temp. and precipitation |
| Global winds move heat | from equator toward poles |
| Solar intensity | sun is most intense at equator, less toward poles |
| occluded front | cold front over takes warm front |
| Symbol for cold front | line with triangle |
| symbol for warm front | line with 1/2 circles |
| symbol for stationary front | line with triangle on one side, and 1/2 circle on the other |
| eye wall | strongest winds of hurricane |
| hurricanes on land loose power | friction and lack of warm water to feed it |
| Hurricanes form | between 5 -20 degrees latitude |
| Hurricane scale | Saffir - Simpson |
| close isobars | high winds |
| winds around high pressure | clockwise |
| winds around low pressure | counterclockwise |
| El Nino | Warm near South America, Dry in Australia and Indonesia |
| La Nina | Cold ocean by South America, Wet in Austrailia and Indonesia |
| Cold front | cold air moves into area where warm air has been |
| Warm front | warm air moves into area where clod air has been |
| Stationary front | cold air and warm air can pass each other with out moving into the other. |
| maritime polar air mass | cold and wet air mass |
| maritime tropical air mass | warm and wet air mass |
| continental polar | cold and dry air mass |
| continental tropical | warm and dry air mass |
| which way does air move at high pressure | subsides or descends |
| which way does air move at low pressures | ascends |
| We like high pressure because | the weather is clear |
| Storms usually move across US | from west to east |
| West winds | come from the west |
| Air pressure pushes | in all directions |
| Ultimate source of energy for most winds | sun |
| isobars are lines that | connect equal pressure |
| isotherms are lines that | connect equal temperature |
