|---|---|---|---|---|---|
| How do clouds and precipitation form? | when air is cooled below its dew point and water vapor condenses into water droplets or ice crystals
🗑
|
||||
| condensation nuclei | what the water vapor condesnses onto- salt, dust, or smoke
🗑
|
||||
| All clouds (do, do not) result in precipitation. | do not
🗑
|
||||
| Why don't all clouds result in precipitation? | water vapor or ice crystals must be heavy enough to fall
🗑
|
||||
| Clouds that cover large areas of sun and look like blankets of fog | stratus
🗑
|
||||
| dark clouds usually resulting in continuous rain | nimbostratus
🗑
|
||||
| puffy white clouds with flat bottoms that indicate fair weather | cumulus
🗑
|
||||
| Cumulus clouds that can produce thunderstorms | Cumulonimbus
🗑
|
||||
| Thin feathery white clouds found at high altitudes, forms when wind is strong, if they get thinker or lower they may indicate approaching bad weather | Cirrus
🗑
|
||||
| any cloud that produces precipitation | Nimbo/Nimbus
🗑
|
||||
| High clouds made of ice crystals classified by altitude | cirro
🗑
|
||||
| middle clouds that can be made of both water and ice classified by altitude | alto
🗑
|
||||
| low clouds made of water classified by altitude | strato
🗑
|
||||
| precipitation | water that falls from the air to the Earth- rain , snow , sleet or hail
🗑
|
||||
| rain | liquid water that falls from clouds to the Earth, must get large enough to fall from the cloud
🗑
|
||||
| snow | most common solid precipitation
🗑
|
||||
| sleet | freezing rain that fall through layers of freezing air
🗑
|
||||
| hail | solid precipitation that forms as balls or lumps of ice
🗑
|
||||
| rain gauge | instrument that measures the amount of rainfall
🗑
|
||||
| air mass | an area of the atmosphere where the characteristics of the air are the same
🗑
|
||||
| Air mass is represented on a map by two letter. The first is ___ and the second is _____. | moisture, temperature
🗑
|
||||
| Air masses are determined by their _____ where the air came from | source region
🗑
|
||||
| Maritime air mass- M- formed over water, air is ____ | wet
🗑
|
||||
| Continental air mass formed over land, air is ____ | dry
🗑
|
||||
| Arctic air mass (A), air is ____ | cold
🗑
|
||||
| Polar air mass (P), air temperature is ____ | relatively low
🗑
|
||||
| Tropical air mass (T), air temperature is _____ | relatively high
🗑
|
||||
| Air masses are moved by _____ and _____ | planetary winds and the jet stream
🗑
|
||||
| Acrtic and polar air masses are moved in what two directions? | south and west over US
🗑
|
||||
| Tropical air masses are moved to the _____ and _____ by the southest wind belt between 30 and 60 degrees North | north and east
🗑
|
||||
| Fronts | area where two air masses meet
🗑
|
||||
| Cold front | leading edge of cold air mass. Cold air forces the warm air upward
🗑
|
||||
| Cold air masses move (faster, slower) than warm air masses | faster
🗑
|
||||
| Warm front | a warm air mass follows a cold air mass. The warm lighter air rides over the top, cools and reaches its dew point and causes precipitation
🗑
|
||||
| Stationary front | form where a cold air mass meets a warm air mass and neither moves
🗑
|
||||
| Occluded front | when two cold air masses meet with a warm air mass in the middle and the warm air is pushed upwards
🗑
|
||||
| Frontal cyclones | areas of high pressure move towards area of low pressure and are bent to the right due to Coriolis effect
🗑
|
||||
| cyclone- (high, low) pressure system in inward counterclockwise direction | low
🗑
|
||||
| anticyclone- (high, low) pressure system in outward clockwise direction | high
🗑
