According to PAGASA, about 20 tropical cyclones hit the Philippines each year, forming over warm ocean waters. Tropical cyclones are categorized based on maximum wind speeds, from tropical depressions under 64 kph up to supertyphoons over 200 kph. Most tropical cyclones in the Philippines form over warm ocean waters and tend to move west-northwest across the Philippine Sea at speeds around 19-20 km/hr.

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.
