Weather Map Notes 2026

Weather Map Notes

• Weather refers to the conditions of the
atmosphere at a given time and place.
A location’s weather depends on:

•
air temperature

•
air pressure

•
humidity

•
cloud cover

•
precipitation

•
wind speed and direction

• All of these characteristics are directly
related to the amount of energy that is
in the system, and where that energy
is. The ultimate source of this energy is
the Sun.

Multiple Choice

What is the ultimate source of energy causing weather?

• sun

• precipitation

• earth

• wind

• What Causes Weather?

• Weather occurs because of unequal
heating of the atmosphere. The
source of heat is the Sun. The general
principles behind weather can be
stated simply:

•
The Sun heats Earth’s surface
more in some places than in others.

•
Where it is warm, heat from the Sun
warms the air close to the surface.
If there is water at the surface, it
may cause some of the water to
evaporate and increase the
humidity.

Multiple Choice

What causes weather?

• unequal heating of the atmosphere

• amount of cloud cover

• season we are in

• hemisphere we are in

• What Causes Weather?

• Warm air is less dense, so it

rises. When this happens,
more dense air flows in to
take its place. The flowing
surface air is wind.

• The rising air cools as it goes

higher in the atmosphere. If it
is moist, the water vapor may condense.

Clouds may form, and
precipitation may fall.

Multiple Select

Which one is less dense? Choose all that apply (2)

• warm air

• cold air

• 80F

• 50F

Multiple Choice

Flowing surface air due to warm air rising and cooler air flowing in to take its place in an area, causes what to occur?

• wind

• clouds

• precipitation

• sunny weather

Weather Maps

•L= low pressure
system= precipitation
•H= high pressure
system= good weather
•Isobars= areas with the same air pressure


Front symbols are
pointed in the direction
the front is moving.

Weather Maps

Multiple Choice

What city is the warm front moving towards?

• Minneapolis

• San Francisco

• New York

• Denver

Multiple Choice

What city is the cold front moving towards?

• Minneapolis

• San Francisco

• Houston

• Seattle

Multiple Choice

A low pressure system is moving towards Denver, what kind of weather should they expect?

• sunny weather

• rainy weather

Multiple Choice

A high pressure system is over Minneapolis, what kind of weather should they expect?

• sunny weather

• rainy weather

Any area along the same line or within the closed shape has the same air pressure. This is shown on a map using isobars.

​Isobars

Multiple Choice

What state has the same air pressure as Wyoming (WY)?

• Nevada(NV)

• Texax(TX)

• Alabama(AL)

• Virginia(VA)

Multiple Select

What two states has the same air pressure as Georgia(GA)?

• Nevada(NV)

• Texax(TX)

• Alabama(AL)

• Virginia(VA)

Multiple Choice

Meteorologist's use diagrams, maps and charts when they present the weather. How does this help people understand weather?

• It shows they can't predict the weather

• It show how to change the weather

• it shows that many components(factors) impact the weather

• It shows that only temperature affects the weather.
