2.  Weather Disturbances
 Typhoon/Hurricane
 Tropical Cyclones
 Tornado
 Tsunami

4.  Typhoon/Hurricane
 Tropical Cyclones
 Tornado

6. - A large heat engine,
where great amounts
of heat are being
produced from the
process of latent heat
of condensation.

7. - Both are names of
tropical storms
and most of their
characteristics are
the same. They
have
- wind speeds that are more than 74 mph, and are
accompanied by hail, strong winds, storm surges and
rain.

11.  Hurricanes damage
more land areas than
Typhoons, which
cause damage to
countries’ coastlines.
 Hurricanes move both
clockwise and counter
clockwise.
 Typhoons are said
to be stronger than
Hurricanes because
it develops where
water is warm.
 Typhoons move
clockwise.

12.  Pre-existing disturbance
 Warm ocean water
 Low atmospheric stability
 Sufficient Coriolis force
 Low vertical wind shear
 Upper atmosphere divergence

15.  Water temperatures of at least 26.5
°C (79.7 °F)
 Rapid cooling with height
 High humidity
 Low amounts of wind shear
 A need to form more than 555 km (345 mi) or
5 degrees of latitude away from the equator
 pre-existing system of disturbed weather

16.  Around 19 tropical cyclones or storms
 The Philippine Atmospheric, Geophysical
and Astronomical Services
Administration (PAGASA) releases tropical
cyclone warnings in the form of Public Storm
Warning Signals.

20. - Torrential rain that can cause flooding
- Extremely strong winds that carry
debris that can be lethal
- Damage buildings and property
- Destroy crops
- Capsize boats at sea
- Deaths due to drowning
- Infrastructure destroyed

28.  Land encourages the
development of a
tornado, while it destroys
the cyclone’s formation.
 The time frame from the
birth of a tornado until it
dies out, is generally
measured in minutes.
 Cyclones develop and
faster over the oceans.
 The cyclone has a
longer life span. The
time frame from the
birth to the death of a
cyclone, is measured
in hours and days.

29.  loss of Life

 Effects on
Nature

30.  Tsunami are ocean
waves, that can reach
the height of 100 feet,
and crash onto land.
 Japanese word that
means “harbor wave”.
 80% of all tsunamis take
place in the Ring of Fire
in the Pacific Ocean.

31.  Tsunamis are formed as a
result of powerful under
water earthquakes, volcanic
eruption, or a landslide
 Some parts of the Ocean
experience frequent
earthquakes because of the
movement of the continental
plates.

32.  In deep open sea,
tsunamis move at a
speed of 600 mph or
more.
 When tsunami arrives
at the shore, it usually
decreases its speed to
about 45 mph/hour.

43.  August 16, 1976
 Cotabato Trench
 Maximum height
of 4.5 meters
(14-15 feet)

44.  15 November 1994
 Earthquake with magnitude of 7.1
 Baco, Mindoro

45.  Tsunami may affect
people mentally,
emotionally, and
financially.
 People are left homeless
and careless due to the
flooding and other
destructions.
 Lost of lives

46.  Destroy the crops and flood the city.
 A tsunami can cause
plenty of damage by
crushing buildings,
sweeping people of
their feet, and dirtying
the pipes,
consequently
spreading disease.
