study of climate, They learn the
climate of a place by analyzing its
weather from season to season and
year to year.

16. FACTORS AFFECTING CLIMATE:
1. LATITUDE
-an imaginary line that is parallel to the equator.
-The equator receives much of the radiant
energy released by the sun, so places near the
equator have warm climate. The areas closer to
the poles receive less amount of heat because
the angle of sunlight becomes smaller.

19. Earth's axial tilt (also
known as the obliquity of
the ecliptic) is about
23.5 degrees. Due to
this axial tilt, the sun
shines on different
latitudes at different
angles throughout the
year. This causes the
seasons.

22. FACTORS AFFECTING CLIMATE:
2. ALTITUDE
-the height above sea level
-The altitude of a place will affect the air temperature. That’s
because the air Temperature decreases as the altitude
increases. For every 1000 m, there is a drop of 6.50C. At
higher elevations, there is less air. The air molecules are
farther apart, thus making the air less dense. Lighter air
cannot absorb much heat, making air temperature lower.
Ultimately, the decrease in air temperature is due to the
decrease in air pressure.

23. FACTORS AFFECTING CLIMATE:
Altitude in Baguio
1,500 m (18.3 degrees Celsius)

26. FACTORS AFFECTING CLIMATE:
3. TOPOGRAPHY
-the surface features of an area.
-shape of the land

27. -Mountain is an example of
topographical features of the land.
As you noticed, the picture shows
the two sides of the mountain. One
side is facing the wind and has low
temperature. Clouds are forming
here due to the condensation of
water vapor. This formation of
clouds develops to become rain. On
the other side of the mountain,
there is no cloud formation. The
temperature is high and
precipitation does not happen. This
results in the formation of a dry and
warm region.

28. FACTORS AFFECTING CLIMATE
Windward
Leeward
The windward side of the
mountain faces the wind
and receives warm, and
moist air.
The leeward side of the mountain is the
opposite side of the windward. The air
that goes down the leeward slope has
lost its moisture on the windward side
resulting to warm air and
low relative humidity.

29. FACTORS AFFECTING CLIMATE:
4. OCEAN CURRENT
-Great flows of water running in the oceans are called ocean
currents. Some currents bring warm water to cool areas.
Warm ocean currents stream from the tropical seas toward
the polar areas. Other ocean currents bring cool water to
warm areas. These currents influence climate in many parts
of the world.

30. FACTORS AFFECTING CLIMATE:

31. FACTORS AFFECTING CLIMATE:
5. WIND SYSTEMS
-light and gentle winds
-People residing nearby oceans and lakes feel
the breeze. There are two types of breeze – land
breeze and sea breeze.

32. FACTORS AFFECTING CLIMATE:
Sea Breeze- During
the day, warm air
over the land rises
and is exchanged by
the cool air over the
water.

33. FACTORS AFFECTING CLIMATE:
Land Breeze- During
the night, the land turns
out to be cooler than
water. Warmer air over
the water increases and
is replaced by cooler
air from the land.

34. FACTORS AFFECTING CLIMATE:
The Philippines is influenced by these
following wind systems:
a. NORTHEAST MONSOON
b. SOUTHWEST MONSOON

35. FACTORS AFFECTING CLIMATE
The Philippines is influenced by these
following wind systems:
a.NORTHEAST MONSOON
(AMIHAN)
b. SOUTHWEST MONSOON
(HABAGAT)

37. NORTHEAST MONSOON
From October to February, a high-pressure region builds
over Southern Siberia and India in winter because of the
cold air over these areas. This mass of cold air goes in the
direction of the Pacific Ocean. It reaches the Philippines
from a northeasterly direction, as a result, the name
northeast monsoon. This monsoon gives cold mornings
and strong rainfall along the eastern coastal regions of the
Philippines.

38. SOUTHWEST MONSOON
From June to September, the continent of Asia turns
out to be warmer than the oceans nearby. A cold air
mass builds over the Pacific Ocean. It goes toward
the Asian continent from a southwest direction.
Southwest monsoon gives heavy rainfall along the
western coastal regions of the Philippines.

39. FACTORS AFFECTING CLIMATE:
6. EARTH’S MOVEMENT
AFFECTS CLIMATE
The earth spins on its axis every day. One side of it
faces the sun and is completely lighted while the other
side is in darkness, as it rotates. The earth’s axis is
inclined at 23 ½ degrees. Because of this, some
portions of the earth receive vertical rays while other
parts receive diagonal rays.
