DONT FAIL FAILURE
why does the warm, moist air rises over the frontal boundaries?
warm air is less dense than cold air
What causes the winds to curve on the planet and what is it called?
earth rotation and the Coriolis Effect
what is the climate like on the leeward side?
drier and warmer
what is the climate like on the windward side
more moist, and cooler
most clouds form in the atmosphere when moist air…?
rises, expands, and cools to the dew point (RECCD)
air pressure is usually highest when the air is…?
cool and dry
if pressure is between 0-499 then u add…
10
if pressure is between 500-999 then u add..
9
how do you know if a map is displaying strong winds
close disbars (vise-versa)
which direction doe s prevailing winds blow to and from
east to west
what weather condition is most probable when the moisture content of the air increases, resulting in a lower atmospheric pressure?
cloudy with a chance of precipitation
when dew point and air temp are close together what does that indicate?
the humidity is high, meaning its close to 100%
when the dew point and air temp are far apart and air pressure is rising what type of weather is most likely coming?
cool, dry air
what instrument measures wind speed
anemometer
what instrument measure wind direction
wind vane
what instrument measures pressure
barometer
what instrument measures relative humidity
sling psychrometer
what instrument measures temp
thermometer
what instrument measures how much rain falls in a specific area over a period of time
rain gauge
air capacity
amount of water vapor that air can hold at a temperature
dew point
temperature of which air becomes completely saturated
humidity
amount of moisture in the air
as temp of the air mass increases…
moisture capacity increases
as temp of the air mass decreases
moisture capcity decreases
