Winds and water (chapter 6) Flashcards
Movement of air from areas of high pressure to areas of low pressure
Wind
Blow over short distance,
Created by unequal heating
occur within a small area
Local Winds
Blow steadily over long distance
created by unequal heating
occur over large area
Global winds
What is the name of the effect that causes the Northern hemisphere global winds curve to the right, and Southern hemisphere global winds curve to the left?
Coriolis effect
Steady winds that flow from WEST between 30n latitude and 30s latitude
Trade winds
Cold winds that blow from EAST to WEST between latitude lines 30n and 60n and 30s and 60s
Polar easterlies
High winds near top of troposphere generally flowing west and east and are able to influence the weather
Jet streams
amount of water vapor in the air compared to the amount of water vapor the air could hold at a temperature
Relative humidity
Temperature at which air is fully saturated because of decreasing temperatures
dew point
Form when water vapor in the air condense to form liquid water or ice crystals
clouds
How do scientist classify clouds?
Their shape and altitude
What are the three main clouds?
Cirrus
cumulus
stratus
Water, in liquid or solid form, that falls from the atmosphere; common types include rain, sleet, freezing rain, snow, and hail
Precipitation
