35. FACTORS AFFECTING
SEASONS IN THE
PHILIPPINES
1. Location of the Philippines
2. Prevailing Winds

36. 1. Location of the Philippines
• The Philippines is located above
the Equator (Tropical
Region).
• Being near the equator, the
Philippines receive the vertical
rays of sunlight.
• Much heat causes water to
evaporate and fall as rain later on.

38. The Light Rays of the Sun

39. 2. Prevailing Winds
• Seasons in the Philippines are
influenced by the prevailing
winds.
• A Prevailing Wind blows mostly
from a single direction.

40. Amihan, Habagat and Easterlies

41. 2. Prevailing Winds
• The Prevailing winds in the
Philippines:
–Southwest Monsoon
(Habagat)
–Northeast Monsoon (Amihan)
–Easterlies (Trade Winds)

43. Prevailing Winds
• The Southwest Monsoon
blows from May to October.
• The Northeast Monsoon
blows from November to
early May.

44. The Four Climate
Types in the
Philippines
Type I Climate
Type II Climate
Type III Climate
Type IV Climate

45. Climate Map of
the Philippines
Philippine
Climate is further
classified into
four types shown
in the map in
four different
colors.

46. Type 1 Climate
• Pronounced Rainy and Dry
season.
• Occidental Mindoro, Negros,
Palawan, Southern Iloilo

47. Type II Climate
• Wet Climate all year round.
• From November to April there is
a heavy rainfall and light rainfall
on the rest of the months.
• There is no pronounced dry
season.
• Ex: Eastern Mindanao, Eastern
side of the Philippines.

48. Type III Climate
• Short Dry Season and a Rainy
season that is not very
pronounced.
• It has no maximum rain period.
• Ex: Masbate, Romblon,
Northeastern Panay

49. Type IV Climate
• Lack of Dry Season and Rainfall.
• Ex: Batanes, Central,
Marinduque and Southern
Mindanao.

51. FACTORS AFFECTING
THE WEATHER
PATTERNS IN THE
PHILIPPINES

52. 1. Air Masses
• An air mass is a large body of air
that has characteristics similar to
the region of the Earth’s surface
where it come from.
• The location of the air mass where
it is developed determines its
characteristics.

54. 2. Fronts
• A front is a boundary between
two air masses of different
densities, moisture or
temperature.
• There are four types of fronts-
cold, warm, occluded and
stationary.

56. Warm Front
• A warm front is the boundary
along a warm air mass,
pushing out a cold air mass.
• When a warm front moves
forward, clouds in the sky bring
steady rain.

57. WARM
FRONTS
warm air advances and gently moves over cold
air- causes rain showers

58. Cold Front
• A cold front is the boundary
along the leading edge of a
cold air mass pushing out a
warm air mass.
• When cold air mass moves, it
pushes and lifts the warm air
mass.

59. COLD FRONTS
cold air pushes warm air up violently- Causes
severe weather.

60. Occluded Front
• An Occluded Front is formed
when a cold air mass moves
toward each other with warm
air between them.
• The colder air pushes warm air
upward, clouds develop and a
steady rain is experienced.

61. Occluded Front

62. Stationary Front
• A Stationary Front occurs when
a boundary between air
masses stops moving. The
stationary front may remain in the
same place for several days.
• The place will experience light
wind and rain.

63. Stationary Front

64. 3. Prevailing Winds
• Prevailing winds blow mostly
in one direction.
• The Prevailing winds in the
Philippines are the Southwest
Monsoon (Habagat) and the
Northeast Monsoon
(Amihan).
