🗑
|
||||
| low fluffy clouds | cumulus
🗑
|
||||
| low flat clouds that cover most of the sky | stratus
🗑
|
||||
| mid-level fluffy clouds | altocumulus
🗑
|
||||
| low flat clouds that bring precipitation | nimbostratus
🗑
|
||||
| It may begin as rain, but the ground is below freezing. | freezing rain
🗑
|
||||
| the temperature is below freezing in the cloud and the temperatures remain below freezing all the way down. | snow
🗑
|
||||
| this travels through a cumulonimbus cloud, where layers of ice may build up until it is too heavy to remain in the cloud. | hail
🗑
|
||||
| two things necessary for clouds to form | cooler temperatures reaching to dew point and a particle to cling to.
🗑
|
||||
| The process of water vapor cooling and becoming a liquid form, creating clouds. | condensation
🗑
|
||||
| warm and humid air masses | maritime Tropical
🗑
|
||||
| cold and dry air masses | continental Polar
🗑
|
||||
| air masses are described by two things. | temperature and humidity
🗑
|
||||
| when two air masses collide, but do NOT mix | fronts
🗑
|
||||
| these fronts stall because one air mass can not move the other- brings many days of rain | stationary fronts
🗑
|
||||
| warm air masses overtakes and rises above a cold air mass- usually brings warm humid air | warm front
🗑
|
||||
| the amount of moisture in the air | humidity
🗑
|
||||
| percentage of water vapor in the air, compared to the actual amount there. | relative humidity
🗑
|
||||
| this storm can bring heavy damages with flash flooding,strong winds and lightning strikes. | thunderstorms
🗑
|
||||
| this storm usually developes in thick cumulonimbus clouds and is a rapidly whirling funnel-shaped cloud. | tornado
🗑
|
||||
| most tornadoes occur here, where cold air masses from Canada meet warm, humid air masses from the Gulf of Mexico. | tornado alley
🗑
|
||||
| this long-lasting storm is fueled by warm tropical water evaporating and can have strong winds. | hurricanes
🗑
|
||||
| clouds are classified by what 2 things? | altitude and shape
🗑
|
||||
| fronts are classified by what 2 things? | temperature and humidity (cold/wet)
🗑
|
||||
| how warm weather will change after a cold front comes through? | it will rain, then cooler, drier air will come.
🗑
|
||||
| What will result when clouds are above freezing, the air is also above freezing,but the ground is below freezing. | freezing rain
🗑
|
||||
| What will result if the cloud is below freezing, but the air is above freezing? | sleet
🗑
|
||||
| What will result if the cloud is below freezing, and the air is below freezing? | snow
🗑
|
||||
| this prefix/suffix means precipitation is probably coming | nimbo/nimbus
🗑
|
||||
| this prefix means "high", but are really mid-level clouds | alto
🗑
|
||||
| this prefix means "VERY high" | cirro
🗑
|
||||
| used to measure relative humidity | psychorometer
🗑
|
||||
| someone who studies and forecasts weather: may use weather baloons, barometers, theromometers, radar, satellite images. | meteorologist
🗑
|
||||
| a dome of water that occurs during hurricanes, that brings flooding. | storm surge
🗑
|
||||
| thunderstorms may bring what dangers? | rain, thunder, lightning, flash floods and tornadoes
🗑
|
||||
| What causes hurricanes to lose strength or "die out"? | moving to land - there is no warm water to keep evaportating and fueling the storm.
🗑
|
||||
| Where is the best place to be for a tornado? | a storm shelter, basement or a room with no windows.
🗑
|
||||
| rain that freezes as is falls | sleet
🗑
|
||||
| rain that freezes after it touches the ground | freezing rain
🗑
|
||||
| this begins as frozen water vapor, and NEVER melts | snow
🗑
|
||||
| What causes hurricanes to develope? | The sun's energy causes warm water to evaporte along the areas near the equator; as the warm most air rises, it cools and oondenses, bringing wind and rain.
🗑
|
||||
| a violent disturbance in the atmosphere created by sudden changes in air pressure | storm
🗑
|
||||
| the temperature at which water vapor changes to a liquid | dew point
🗑
|
||||
| this type of front will bring warmer, humid air and may bring some rain/snow | warm front
🗑
|
||||
| this type of front will bring cold, drier air and heavy rains/snow | cold front
🗑
|
||||
| this front has two cold air masses pushing up a warm air mass and cutting it off. | occuluded front
🗑
