An air mass that forms over an
ocean is called?
A maritime air mass
What are lines joining places that have the
same temperature?
isotherms
Cool, clear weather usually follows a _________ front.
Cold Front
________________is a sudden spark or electrical
discharge, as electrical charges that jump
between parts of a cloud or between a cloud and
the ground.
Lightning
On a weather map,________________j
oin places on the map with the same
air pressure.
isobars
If you observe air pressure decreasing, what kind of weather do you think is coming?
Clouds and precipitation
A thermometer measures
Air Temperature
In Fahrenheit the freezing
point of water is….
32 degrees Fahrenheit
In Celsius the boiling point of
water is …
100 degrees Celsius
How are air masses
classified?
By Temperature and Humidity
A rapidly moving cold air mass meets a slowly moving warm air mass and forms a front. What will most likely occur at this front?
Cold air will slide under the warm air. Warm air will rise and cool and clouds will form.
What is the main way the
troposphere is heated?
Convection Currents
What are the three major global wind
belts?
Trade Winds, Polar Easterlies and the
Prevailing Westerlies
The two areas of calm are
The Doldrums and the Horse
Latitudes
The instrument used to measure
wind speed is called a
Anemometer
A scientist who studies the causes
of weather and tries to predict
weather is called a ______?
Meteorologist
Bands of high speed winds above the
Earth’s surface are called__________?
Jet Streams
The increased cooling that a
wind can cause is called
The Wind Chill Factor
What is the natural process where
gases hold heat in the air called?
The Greenhouse Effect
What is an air mass?
A large body of air that has similar temperature, humidity and air pressure throughout.
Name 4 types of fronts?
A. Warm
B. Cold
C. Stationary
D. Occluded
How are air masses moved in the US?
A. Jet Streams B. Prevailing Westerlies
A polar air mass has _____________pressure?
High
The boiling point of water in Fahrenheit is …
212 degrees fahrenheit
A cold air mass and a warm air mass meet and remain stalled over an area is a ____________________front.
Stationary Front
What causes winds?
Differences in air temperature and
pressure caused by the uneven heating of
the Earth’s surface
When a warm air mass slides over a cold air mass a _________front is formed.
Warm Front
When a warm air mass is caught between two cooler air masses a(n) _________ front is formed.
Occluded Front
Winds that are found between 0 and 30 degrees
latitude are called
Trade Winds
I am a front that brings light rain for
several days. ____________
Warm or Stationary
Winds that are found between
30 and 60 degrees latitude
are called
The Prevailing Westerlies
I am a front that brings severe
weather. (Heavy downpours, gusty winds and cooler temperatures)
Cold Front or Occluded
