Climate and Weather

1. Climate &
Weather

2. LEARNING OBJECTIVES:
• Explain how different
factors affect the climate
of an area

6. • What is so amusing or funny about these cartoons?
• How are these images related?
• What is the focus of these cartoons?

7. Weather
Temporary behavior of atmosphere
(what’s going on at any certain time)
Small geographic area
Can change rapidly

8. Weather
• The study of weather is
meteorology
• Someone who studies
weather is called a
meteorologist

9. Climate
Long-term behavior of
atmosphere (100+ years)
Large geographic area
Very slow to change

10. Climate Zones

11. Climate Zones
• Tropical
• Temperate
• Polar

12. Climate Zones
Tropical Climate
• 30 degrees - equator
• No winter, warm year-
round
• High temp, rainfall,

13. Climate Zones
Temperate
• 60-30 degree latitude
• True Seasons
• Variety of climate patterns
• Moderate precipitation
(rain/snow)

14. Climate Zones
Polar Climate
• 90 -60 degree latitude
• Cool summers, cold year-round
• Dry
• Found near the poles,
characterized by cold
temperatures and little

15. Climate Zones
Dry Climate
• Found in arid
regions with
low
precipitation,
such as

16. What are the factors that
influence the weather?

17. Temperature
It is the degrees
of hotness or
coldness of the
place

18. Wind
It is the
movement of
air in the
atmosphere Anemometer

19. Air Pressure
• It is the force
caused by the
weight of air in
the Earth’s
surface
• It is the force
Barometer

20. Humidity
• It is the amount
of water vapor in
the air
Hygrometer

21. Precipitation
It is the water
falling from the
atmosphere, in
the forms or rain,
snow or hail.
Rain Gauge

22. What are the factors that
influence the climate of a
certain place?

23. Latitude
• It is the distance (in
degrees) to the
North and South
from the EQUATOR
• It is an imaginary
line that is parallel
to the equator

26. Why is it that during summer many
people visit Baguio City?

27. Altitude
Elevation or altitude refers to how
high a region is from the sea level.
The higher the elevation, the
colder is the climate. This is the
reason why Baguio City
experiences cold weather system.

28. Altitude
Temperature
decreases as
the altitude
increases.

29. Ocean currents and Temperature
A body of water such
as an ocean and its
currents tend to
increase the
temperatures of
eastern coastal areas
and decrease the

30. Ocean currents and Temperature
Land heats and cools faster than the sea.
Coastal areas have lower temperatures than
inland areas

31. Ocean currents and Temperature
Places that are far from the bodies of water
have extreme climates.

32. Precipitation
The amount of humidity
or water vapor in the air
determines the rate and
amount of precipitation
in the area. Usually, when
the atmosphere becomes
full of water vapor, the
likelihood or chance of
precipitation becomes

33. Air Masses
Air masses are large areas
of air that have uniform
temperature and
moisture content. They
form over “source”
regions. The air mass
assumes the properties of
the surface of the source
region; that is, it could be

34. Mountain Barriers
The rising air is cooled, which causes condensation
of water vapor and precipitation. This causes
windward side to have more precipitation and
vegetation, and leeward side to be often drier. The
Sierra Madre Mountain Ranges is a great barrier in
which the province of Pangasinan adopts very
