CLIMATE

CLIMATE
2

• Weather is the condition of the atmosphere in a
  place for a short period of time.
• Climate is the average weather condition of a
  place for a longer period of time.

3
Different Climate in the 3 zones

• Torrid Zone-------- Tropical Climate
• ( wet and dry seasons)
• Temperate Zone Temperate Climate(winter,
  spring, summer,fall)
• Frigid Zone-------- Cold Climate (very cold snow
  all year)

4
Factors Affecting Climate

• altitude
• latitude
• rays of the sun
• bodies of water
• amount of rainfall
• wind system

5
1.Altitude

• Elevation
• The height of a place above sea level.
• The climate in higher places is cooler than in
  lowlands.
• As height increases, air becomes thinner or less
  dense (cant hold much heat)
• For every 1 000 ft increase in height, the
  temperature drops by 3.5 ºC. ( 1 000 km ----
  decrease of 7 ºC)
• Example Baguio and Tagaytay

2.Latitude

• - the distance of a place North or South of the
  equator.
• The nearer the place is to the equator, the
  hotter it is the farther the place is, the
  cooler it gets.
• The equator receives direct sunlight, thus the
  temperature in places near it is high.

3. Rays of the Sun

• The amount of sunlight a place receives
• Equator direct rays from the sun (more
  heat/radiation)
• Temperate zone slanting rays from the sun (less
  heat)
• North/South Pole very little heat from the sun

4. Bodies of Water

• Oceans, seas, and other bodies of water control
  the earths temperature.
• Places near bodies of water are cooler than areas
  surrounded by other land areas.
• Land absorbs and loses heat quickly, while water
  absorbs and loses heat slowly.
• Land Breeze (Night time) cold air comes from
  the land
• Sea Breeze (Day time) - cold air comes from the
  water

5. Amount of Rainfall

• Tropical areas are hot, with monthly temperature
  above 64.4 ºF or 18 ºC and they receive large
  amount of rainfall.
• Temperate zone, there are differences in
  temperature and precipitation patterns. Winter
  can be quite cold because of heavy snowfall with
  at least one month, averaging below freezing
  point (-3ºC or 26.6 ºF). The warmest month has an
  average temperature of 50ºF or 10ºC.
• Polar areas are extremely cold. They are quite
  dry although water is abundant in the form of
  solid ice.

6. Wind System

• - Wind is moving air. It is formed by the unequal
  heating of the Earths surface.
• - The Philippines geographical location
  contributes to its prevailing wind systems
• a. Northeast Monsoon Hanging Amihan from Nov
  to March blows from Siberia towards the
  Philippines brings the cold temperature from
  northern hemisphere(winter).
• b. Southwest Monsoon Hanging Habagat from
  June to October develops because of the cold air
  mass coming from the south, Australia, where it
  is winter. This cold front meets the warm front
  in the Philippines and causes the rainy season in
  the western part of the country.
• c. Trade Winds from March to early May blows
  from the North Pacific Ocean and reach the
  Philippines from the east. It brings rain only to
  the eastern part of the country.

• Philippines is located in the Torrid Zone, with
  tropical climate and also with
• 4 types of climate
• Type 1- Two pronounced and 2 season dry
  from December to May, and wet
• from June to September
  (Ilocos, Zambales, Central Luzon)
• Type 2- No dry season with maximum
  rainfall in Dec to Jan. (Catanduanes,
• Camarines Sur/Norte, Samar,
  Leyte, eastern Mindanao)
• Type 3- Short dry season that lasts only
  from 1 to 3 months with no very
• pronounced maximum rain
  period. (Cagayan, Isabela, Nueva Viscaya,
• Kalinga, Apayao, Benguet,
  Ifugao)
• Type 4- Rainfall is evenly distributed
  throughout the year. (Batanes,
• Northeastern Luzon, western
  part of Camarines Sur/Norte, Albay,
• western Leyte)
• 2 seasons (wet and dry)
• - The Philippines has very little changes in
  temperature but there are great
• changes in rainfall because of its
  topography.
• Climate Change- is a broader term that refers
  to long term changes in climate, including
  average temperature and precipitation.
