Meteorology
What are two properties of Earths atmosphere that change with altitude
Air tempature and pressure
Where does weather occurs?
In the troposphere
What are isolines used for?
Connect equal temperature
How does temperature affect density?
As temperature increases, density decreases
What is needed for condensation to form?
A solid surface
What is humidity?
The amount of water in the air
How is humidity and dew point measures
A sling psychrometer
How can air pressure be converted?
ESRT
How is air pressure modeled on a map?
Isobars
What does wind speed depend on?
Pressure gradient
How is wind speed measured?
Anemometer
what does the closer the isobars mean?
Faster the wind
What does the farther the isobars mean?
The slower the wind
what does pressure center mean?
Highest or lowest pressures on a weather map
What does it mean when air pressure is decreasing?
Stormy weather
what is a wind vane?
A instrument that indicates the compass direction the wind is coming from
How is temperature measured?
What is weather?
Short term atmospheric conditions in a septic area at a specific time.
How much water can air hold.
1 gram of water for each cubic yard of air.
What does relative humidity mean?
The air is saturated. (Full of water)
How do clouds form?
Parcel of warm air rises it expands and cools to the dew point tempature to form a cloud.
What are the forms of precipitation.
Rain, drizzle, snow, sleet, freezing, rain, hail.
How does altitude affect tempature?
As altitude increases in the troposphere, the temperature decreases because the air gets thinner.
What are ten factors that affect the weather?
Temperature, air pressure, humidity, and winds.
What are the three major temperature scales?
Celsius, Fahrenheit, and Kelvin scales.
