How do the days and nights vary
throughout the year for Japan, Korea,
Indonesia?
• Because Earth is tilted on its axis, the lengths of
days and nights change throughout the year.
• Each day, depending on if the North Pole is tilted
towards the Sun or not, days become longer or
shorter as the year goes on.
• No EXTRA long or short days happen occur in
Japan, Korea or Indonesia

Latitude Locations
• Japan (36 00 N, 138 00 E) and
Korea (37 00 N, 127 30 E) are
North of the Tropic of
Cancer(23 20 N).
• Indonesia(5 00 S, 120 00 E) is
almost on the equator.

The Plate Tectonics of the Area
• Japan and Korea were formed by two events:
sub-duction resulting in volcanic activity and the
opening of the Japan Sea. In the case of Japan, the
Pacific Plate and the Philippine Plate sub-ducted the
eastern border of the Eurasian Plate.
• Japan is located on the Pacific Ring of Fire
• Indonesia is at the boundary of four tectonic plates
–
–
–
–
The Indo-Australian Plate
The Pacific Plate
The Philippine Plate
The Eurasian Plate
(this results in intense and frequent earthquakes which
intern cause tsunamis)
GEOGRAPHY
Japan:
About 73% of the archipelago is mountainous, with a mountain
range running through each of the main islands. Japan's highest
mountain and volcano is Mt. Fuji, with an elevation of 3776 m.
Most rivers are fewer than 300 kilometers in length (Shinano River
is the longest river.)
Korea:
Mountains cover 70% of the Korean peninsula
Highest mountain in Korea is Baekdusan
Main rivers tend to flow westwards. 2 exceptions are the
southward-flowing Nakdonggang and Seomjingang.
Indonesia:
archipelago of 17,000 islands
mostly coastal lowlands
The inland is predominantly mountainous with some 400
volcanoes, of which 100 are active
Atmospheric Pressure at the High
Points and Low Points in the Area
• Regions of low pressure form over central Asia and southwest
Asia (Asiatic Low). These pressure systems are responsible for
the summer monsoon rains of Asia.
• As with heat, so also with atmospheric pressure, the yearly
variations in Japan are less than on the neighboring continent.
• Indonesia experiences high atmospheric pressure; high
atmospheric pressure causes only normal winds of between
25 to 30 knots, but because this is persistent, it has caused
massive waves… tsunamis.
HUMIDITY
• Japan is generally a rainy country with high
humidity, ranging from the low 60% to low 80%
depending to the proximity to the coast.
• Since the Korean peninsula is located on the
East-Asian monsoon, summers bring heavy
rainfall and high humidity.
• Being in a tropical zone, Indonesia has an
average relative humidity between 70% and
90%, with a minimum of 73% and a maximum of
87%.
Wind Patterns in Reference to the
Latitudes
• Japan and Korean experience Westerlies (wind
patterns north of the Tropic of Cancer where
dry air sinks/moist air rises.
• Indonesia experiences Southeastern Trade
Winds (winds south of the equator).
OCEANS
• Japan:
Sea of Japan, North Pacific Ocean, Philippine sea,
and East China Sea
• Korea:
Sea of Japan, Yellow Sea, and the Korea Strait
• Indonesia:
Indian Ocean and Pacific Ocean
These oceans have a salinity of about 35 o/oo, as
they are near the equator.
Climate Zones
• Japan belongs to the temperate zone with distinct four seasons,
but varies from cool temperate in north to subtropical in south.
– Sea of Japan: The northwest seasonal wind in winter gives heavy
snowfalls. In summers it is less hot than in the Pacific area but
sometimes experiences extreme hot temperature.
– Central highland: A typical inland climate gives large temperature
differences between summers and winters and between days and
nights. Precipitation is not large throughout a year.
– Inland Sea: The mountains in Chugoku and Shikoku regions block the
seasonal winds and bring mild climate and many fine days throughout
a year.
– Pacific Ocean: It experiences cold winters with little snowfall and hot,
humid summers due to the southeast seasonal wind.
– Southwest Islands: It has a subtropical climate which varies from
tropical in the south to cool temperate in the north.
• Indonesia: tropical; hot, humid; more moderate in highlands
BIOMES
• Japan:
Tropical and subtropical moist broadleaf forests
Temperate coniferous forests
Freshwater and Marine (ex. Lake Biwa or Nansei Shoto )
• Korea:
Evergreen conifer forests
Deciduous Forests
• Indonesia:
Tropical rain forests
Mangroves
Coral Reefs
Occurrence of Severe Weather
Disturbance
• Japan, Korea and Indonesia; occasional floods, severe
droughts, tsunamis, earthquakes, volcanoes, and forest
fires.
• Japan-tropical cyclones and severe winds, many
dormant and some active volcanoes; about 1,500
seismic occurrences (mostly tremors) every year;
tsunamis.
• Korea-Recently decayed tropical cyclones moving
inland or into southern regions.
• Indonesia-During an El Niño year, tropical rains usually
centered over Indonesia shift eastward, influencing
atmospheric wind patterns world wide… The
earthquakes and cyclones cause intense tidal waves.
CARBON DIOXIDE LEVELS
• As of 2006, Japan expelled 1.3 billion tons of
carbon dioxide a year, making it one of the
world's top offenders.
• Korea emitted about 185 million tons
• Indonesia is now ranked as the 3rd largest
emitter in the world due to deforestation to
create oil pam.
POPULATION
• Japan is post reproductive… Population growth
