•WEATHER refers to the
condition of a place in a
short period of time.
•WEATHER can change
anytime.
8. Weather and Climate

condition of a place in a short
period of time.

condition of a place over long
period of time.
11. Activity 1
Procedures:
1. Study the three pictures on the next
slide.
2. List down the activities that you can do
in each of the mentioned season.
3. Choose one answer for each season
and have a role playing to state your
answer.
14. Season or Climate
• The Philippine climate is warm
and humid, it is considered as
one of the world’s healthiest
tropical climates.
• There are two pronounced
seasons – wet and dry.
15. 1. WET SEASON
• Wet season is characterized
by pronounced rainy season
with thunderstorms .
• Wet seasons starts at June
and peaks in July to
September.
17. WET SEASON
• Daytime temperature ranges
from 30-36 degrees Celsius.
• Night temperature ranges from.
21-28 degrees Celsius
• The air is hot and humid ,
which brings heavy rains and
typhoon.
19. WET SEASON
• During the wettest month, rain
is almost in daily occurrence.
• Precipitation (rainfall) is
highest in the area where
Southwest Monsoon
(Habagat) strikes.
21. WET SEASON
• During rainy season it is
advisable to carry an umbrella
especially in the late afternoon.
• In this season, farmers are
able to plant crops.
25. 2. DRY SEASON
• Dry season is characterized by
hot and cloudless days.
• Between January and May
the climate is usually dry
with occasional rain showers.
28. 2. DRY SEASON
• During January and February,
the air is cold and dry.
• The peak of the Dry Season is in
April with less or no rain
shower throughout the
month.
31. 2. DRY SEASON
• The Dry Season is influenced by
the Seasonal Wind and the
Northeast Monsoon
(Amihan).
• The Northeast breeze from
Siberia and Northern China is
cool and dry, it brings cold
winds and cloudless days.
33. 2. DRY SEASON
• Daytime temperature ranges
from 25-32 degrees Celsius.
• Night temperature is 22
degrees Celsius.
• During dry season, from March
to June temperature can reach
up to 32 degrees Celsius.
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.
41. 2. Prevailing Winds
• The Prevailing winds in the
Philippines:
–Southwest Monsoon
(Habagat)
–Northeast Monsoon (Amihan)
–Easterlies (Trade Winds)
42.
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.
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.
53.
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.
55.
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.
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.
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.
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.
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).
