Clouds
What Influences
Climate
Factiod
100
the condition of Earth's atmosphere at a certain time or place
What is weather?
100
collection of small water droplets of ice crystals that are suspended in the air
What is a cloud?
100
large volume of air in which temp and air moisture form when temp and air are some for an area for a time
What is an air mass?
100
describes weather conditions over a long time
What is climate
100
force of an air molecule pushing on an area
What is air pressure?
200
amount of water vapor in the air
What is humidity?
200
surfaces on which water droplets condense
What is cloud condensation nuclei
200
boundary/ where to air masses form
What is front?
200
angular distance in N or S from the equator
What is latitude
200
air that moves horizontally or parallel to the ground high to low pressure
What is wind?
300
amount of water vapor in the air compared to the amount of water vapor needed to reach saturation
What is relative humidity?
300
frontal- thunderstorms-cold fronts orographic- rain shadow effect
What are the 2 kinds of liftings?
300
low pressure- rainy high pressure- clear
What do the 2 pressure systems weather?
300
surface features of an area combine
What is topography
300
measure of transparency of the atmosphere
What is visibility
400
temperature at which more condensation than evaporation
What is dew point?
400
water vapor that condense very near Earth's surface
What is fog?
400
long distance global winds for 1000km
What is a jet stream?
400
the desert behind a mountain where the air blows but there is no moistness in the air or rain from the mountain
What is rain shadow effect?
400
temperate, polar, tropical
What are the 3 climate zones
500
any form of rain that forms from the clouds
What is precipitation?
500
ground fog- low lying during calm nights sea fog- forms when moist air rises steam fog- evaporation into cold air
What are the 3 types of fog
500
ww- hurricanes monsoons heavy rain
How do ocean currents affect weather?
500
currents on the surface of the ocean
What is a surface current
500
the nonstop movement of water through the atmosphere, ocean and land
What is the water cycle
