Typhoons
{
By Katherine Kosup
This picture is
from NASA. It
shows the
paths of
typhoons.
Typhoons
mostly happen
in the west
Pacific Ocean.
Where do typhoons
typically happen?
This chart
shows the
frequency of
typhoons. As
you can see
October is the
month that has
the most
typhoons
How of often do typhoons
happen?
Ocean water
 Humid, sticky air
 Warm sea surface
temperatures
 Warm or cold air pushing
up (either by getting pushed
up a mountain , by cold air
pushing warm air up, or by
warm air pushing cold air
up.)

What elements are directly involved
with typhoons?
Day 1: “Thunderstorms develop over the sea.”
Day 2: “group to form a swirl of cloud.”
Day 4: “Winds grow; distinct center forms in cloud
swirl.”
Day 7: “Eye forms; typhoon is at its most
dangerous.”
Day 11: “Eye passes over land; typhoon starts to
die.”
This is a typical occurrence of a
typhoons.

Winds: greater than 155 miles for hour.
Storm surge: 18 feet above normal.
Complete roof failure on many homes.
Small buildings blown over or blown away.
All shrubs, trees, and signs blown away.
Major damage to lower flours on all building.
What are the most extreme
conditions for a typhoon?
Saffir-Simpson Scale
Category One: Winds: 74-95 mph. Storm surge: 4-5 feet.
Category Two: Winds: 96-110 mph. Storm surge: 6-8 feet.
Category Three: Winds: 111-130 mph. Storm surge: 9-12 feet.
Category Four: Winds: 131-155 mph. Storm surge: 13-18 feet.
Category Five: Winds: over 156 mph. Storm surge: over 18 feet.
What type of scale is use to classify
typhoons?
1.
2.
3.
Typhoons only have many after affects and one is storm surge.
“Storm surge is when winds produces a rush of seawater that can
devastate coastal areas.” “Storm surge is a local raise in sea level
caused by a combination of wind and low atmospheric pressure.”
“Storm surge can become more destructive on high tide.
Flooding can also be an after affect for typhoons. Many peoples
homes where flooded after a typhoon. Flooding has destroyed
many houses and most people in a typhoon only dye from the
flooding.
The last after affect for typhoons is contaminated water sources.
When salt water gets into the pluming it will contaminate the
water. Contaminated water can be very bad because you could
not use any thing that includes water. Water is a very important
resource so when it gets contaminated it must get fixed soon!
What are the after affects do
typhoons have?
This is a picture of a big flood,
one of the after affects of typhoon



Tropical Depression - An organized system of clouds and
thunderstorms with a defined surface circulation and maximum
sustained winds of 38 MPH (33 knots) or less. Sustained winds are
defined as one-minute average wind measured at about 33 ft (10
meters) above the surface.
Storm Surge - A dome of water pushed onshore by hurricane and
tropical storm winds. Storm surges can reach 25 feet high and be 50–
1000 miles wide.
Storm Tide - A combination of storm surge and the normal tide (i.e.,
a 15-foot storm surge combined with a 2-foot normal high tide over
the mean sea level created a 17-foot storm tide).
What key terms are for
typhoons?




“The word typhoon comes from the Chinese
term tai-fung, meaning great wind.
“In other part of the would typhoons are called
hurricanes and tropical cyclones.
“Typhoons occur most frequently in the late
summer.”
The most noticeable part of a typhoon is the eye
located in the center.
