| average temperature, precipitation, humidity, air pressure, and wind, over time in a particular place | climate |
| the temperature, precipitation, humidity, air pressure, and wind at a specific time in a specific place | weather |
| scientist who gathers and analyzes weather data in order to make and share predictions known as forecasts | meteorologist |
| electromagnetic waves from the sun that travel through space | radiation |
| the transfer of heat by the movement of fluids | convection |
| the formation of wind through the rising of air above warmer surfaces and falling air above cooler surfaces | convection currents |
| the movement of air from areas of high pressure (cooler, denser air) to areas of low pressure (warmer) | pressure gradient force |
| the eastward rotation of the Earth results in the formation of global wind belts | Coriolis Effect |
| the global wind belt that flows W to E from 30-60*N&S that most affects US & Canadian weather | Prevailing Westerlies |
| the global wind belt from 0-30* N&S latitudes used by sailing ships to establish routes to exchange goods | Trade Winds |
| very fast high altitude wind blows from W to E near the top of the troposphere | Jet Streams |
| limited winds like sea and land breezes that are formed by differences in the heating of these materials | Local Winds |
| cycle of water in the atmosphere and on land—evaporation, condensation, precipitation, transpiration, etc. | Hydrologic (water) Cycle |
| the presence of water vapor in the air, one of the factors that determines an air mass’s pressure | humidity |
| compares water vapor in air with the maximum amount air can hold at that temperature using a hygrometer/psychrometer | relative humidity |
| air moving based on its temperature, humidity & pressure; ex: continental polar, maritime tropical | air masses |
| the boundary formed when a warm air mass slides over a colder mass, initially causes stratus clouds and rain, resulting in warm, humid weather after it passes | warm front |
| the boundary formed when cold air mass forces a warm air mass upwards, initially causing cumulonimbus clouds and thunderstorms, resulting in cooler, dry weather | cold front |
| the boundary resulting when two air masses collide bu neither moves | stationary front |
| layered, shapeless clouds that indicate rainy weather | stratus |
| puffy, cottonball clouds that indicate fair weather | cumulus |
| high altitude, wispy clouds of ice crystals that indicate rain only if in thick bunches | cirrus |
| multilevel cloud that is formed by great disturbances in air pressure, indicates thunderstorms | cumulonimbus |
| measures wind speed | anemometer |
| measures air pressure | barometer |
| measures wind direction | wind vane |
| measures precipitation | rain gauge |
| radiofrequency waves bounce off of moving air masses to create a visual pattern to map/predict | Doppler Radar |
| collection of thunderstorms that form over the ocean using warm, humid air, with a low pressure center | hurricane |
| violently whirling winds visible as a funnel-shaped cloud, last only for few minutes over a small area | tornado |
| The three factors that air pressure are: | altitude, temperature, & humidity |
| As altitude increases, air pressure _____________. | decreases |
| As humidity increases, air pressure ____________ | decreases |
| As temperture increases, air pressure ____________ | decreases |
| As altitude decreases, air pressure ____________ | increases |
| As humidity decreases, air pressure ____________ | increases |
| As temperature decreases, air pressure ____________ | increases |
Where is air pressure lower, at the Sea of Galilee or on Mt. Everest?,  | Air pressure is lower at the top of Mt. Everest because as altitude goes up, air pressure goes down., |
| Where is air pressure higher, at the Sea of Galilee or on Mt. Everest?, | Air pressure is higher at the Sea of Galilee because as altitude is lower, air pressure is higher., |
Which cloud type is pictured here and what weather does it predict?,  | Cumulus clouds mean good (fair) weather, |
Which cloud type is pictured here and what weather does it predict?,  | Stratus clouds mean rain and are usually associatted with warm fronts., |
Which cloud type is pictured here and what weather does it predict?,  | Cumulonimbus clouds mean thunderstorms and are associated with cold fronts, |
What front type is pictured here and what will the weather be like as it passes and afterwards?,  | Cold fronts occur as cold air pushes warm air up quickly, causing thunderstorms and resulting in cooler, clear weather., |
What front type is pictured here and what will the weather be like as it passes and afterwards?,  | Warm fronts occur as warm air passes over cold air, causing rain, resulting in warmer and humid weather., |
What type of front is approaching NC on this weather map and what weather will it bring?,  | A cold front--the triangles are pointing towards NC. Thunderstorms followed byu colder, clear weather will occur., |
| What does the "H" over Oklahoma mean and what weather does it indicate?, | High pressure area--cooler temp and clear, nice weather, |
| What does the "L" mean to the north of the US and what weather does it indicate?, | Low pressure area--warmer temp and higher humidity resulting in cloudy and rainy weather, |
| What front has been moving through California (west coast) and what weather will it bring?, | Stationary front since the cold (mountains) and warm (hills) front symbols are opposite each other. This means that neither is moving and so rainy weather will occur for several days., |
| What do the wiggly lines indicate on the map and what does it mean if they are drawn close together?, | Isobars are lines that connect areas of similar air pressure. If they are close together, there is a lot of pressure change, resulting in high winds., |
| What do the wiggly lines indicate on the map and what does it mean if they are drawn far apart?, | Isobars are lines connecting areas of the same air pressure. If they are far apart, that means little change is occuring with little wind., |
