Question | Answer |
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 |
