Administration
(PAGASA), about 20 tropical
cyclones hit the PAR each
year.

5. CATEGORY MAXIMUM WIND SPEED
KILOMETERS PER HOUR (kph)
Tropical Depression 64 kph
Tropical Storm 118 kph
Typhoon 200
Supertyphoon Greater than 200

7. 1.Where did the tropical
cyclones form? On land or in
the ocean?

8. The warm ocean
water heats up the air
above it.The warm
air then rises.The
rising water results in
a low pressure area.
Air in the
surroundings will
then move toward
the area.

9. Warm or
cold?
How does it
affect the
formation of
cyclones?

14. Over the Philippine
Sea,Tropical Cyclones tend
to move on a general west-
northwest (WNW) direction
with an average speed of
19-20 km/hr.
