TYPHOON GRADE 8
1) Tropical cyclones originate in the Intertropical Convergence Zone near the equator where trade winds from the northern and southern hemispheres converge. 2) A typhoon is a tropical cyclone that forms over the northwest Pacific ocean, characterized by strong counterclockwise rotating winds around a low-pressure eye. 3) Two key factors fuel the formation and strengthening of a typhoon - rapid updrafts of warm moist air from the ocean surface, and the condensation and release of heat from this water vapor into the swirling winds.

- 14. This is thelayer where artificial satellites can orbit. Within this layer, ultraviolet radiation causes ionization which manifests visually aurora borealis (northern lights) or aurora australis (southern lights).
- 15. This layer protectsthe earth from meteoric impact. This layer of the atmosphere contains the ozone layer. This is the layer where all the weather disturbances can happen.
- 16. Tropical Cyclones A tropicalcyclone is a storm system characterized by counterclockwise rotating air mass around a central part called eye that has a low pressure.
- 17. Typhoons and Hurricanes Atropical cyclone is called a typhoon or hurricane depending on what specific region this stormy system occurs. Typhoons and Hurricanes are one and the same phenomena although they vary in intensity according to place of origins and conditions.

- 20. Typhoons vs Hurricane s Ifthe tropical cyclone occurs in the Northeast Pacific Ocean, the North Atlantic Ocean, and east of the International Dateline or in the South Pacific Ocean, east of 160 degrees latitude, it is called a hurricane.
- 21. Where do TropicalCyclones originate? Tropical cyclones form in the Intertropical Convergence Zone located around the Equator. It is in this area that trade winds from the Northern and Southern Hemispheres converge.
- 22. How do Typhoonsform? You need two components to have a typhoon to form, the ocean and the heat of warm air. Since heat rises, the warm air is pushed up into the sky and can cause a large swirling action which creates a typhoon. The moisture of the ocean coupled with the heat of the air can keep the typhoon going and growing.

- 26. Heavy rainfall isoften caused by weather disturbance. The major weather disturbance that the Philippines encounter is the tropical cyclone (known as Bagyo). Every year, around 20 tropical cyclones are experienced in the Philippines with varying intensities.
