parts of a
typhoon?
Parts of a Typhoon
• Eye-calm weather, light winds, and clear skies
• Eye wall- This part has the strongest winds and rains.
• Rain Bands- These are the clouds that spin out and make the storm bigger.
How typhoons
develop?
HIGH SEA
TEMPERATURE
The temperature
at the sea
surface is above
26.5 degrees
Celsius
02
WIND SHEAR
Winds have
similar speed
and direction.
03

Stage 1
-NE Trade Winds and
the SE Trade Winds
converge, forming
clouds and
thunderstorms
FORMATION OF
TROPICAL
DISTURBANCE
Stage 2
-When strong winds
pull in warm and moist
air from the oceans,
the thunderstorm
becomes a tropical
disturbance
Stage 3
-Tropical disturbance
can become stronger
as it collects warm and
moist air over the
ocean
Stage 4
-Tropical
disturbance doesn’t
like land and cold
water
Classification of
typhoons
are based from
MAXIMUM SUSTAINED
WINDS
GUSTINESS
MAXIMUM SUSTAINED WINDS
-the highest surface
wind speed average
over a 10 minute
period
GUSTINESS
-sudden temporary
increase in wind
speed over a certain
period
Arrange the following according to the increasing
maximum sustained winds and gustiness.
Super Typhoon
Tropical Storm
Severe Tropical Storm
Typhoon
Tropical Depression
Typhoons rotate in
anti or counterclockwise in the
northern
hemisphere and
clockwise in
southern
hemisphere.
Typhoons rotate
because of Coriolis
Effect.
