1. Quarter 2 – Week 6 Understanding Typhoons

2. What is Typhoons? Tropical cyclone, also called typhoon or “ bagyo ” in our country, an intense circular storm that originates over warm tropical oceans, is characterized by low atmospheric pressure, high winds, and heavy rain.

3. The term typhoon is used only in the northwestern part of the Pacific Ocean. In the northeastern part of the pacific ocean and in the northern part of the Atlantic Ocean , the equivalent term is Hurricane. Thus, a hurricane on one side of the Pacific Ocean will be called a typhoon if it crosses into the other side

4. Tropical Cyclone Wind Signal When PAGASA monitors the tropical cyclones enter the PAR and it is constantly in motion, generally toward the Philippines then it is time to issue warning signals. The Public Storm Warning Signal Number over a threatened or affected locality may be sequentially upgrade or downgraded.

9. How do Typhoons develop? A tropical cyclones forms when winds blow into areas of the ocean where the water is warm which is found near the equator. The better source of water vapor is in the ocean but not all can provide water vapor.

10. How do Typhoons develop? According to scientists, the temperature of ocean water must be 26.5’C or greater. These winds collect moisture and rise, while colder air moves below.

11. How do Typhoons develop? This creates pressure, which causes the winds to move very quickly. In landmasses the typhoon weaken because it’s loses energy in cold, causing them to vanish if the land mass is large.

12. Typhoons move east to west across the country, heading north as they go Storms most frequently make landfall on the islands of eastern Visayas, Bicol region and northern Luzon whereas the southern island and region of Mindanao is largely free of typhoons.

13. Like from the maps, you can see that tropical cyclones generally move in a northwest direction. The reason is because there are large-scale winds that push the tropical cyclones in that direction. All four tropical cyclones struck the northern part of the Philippines. Three of the tropical cyclones are weakened and died out near land. Agaton dissipated in Luzon, Yoyong in Taiwan, and Huaning near Mainland China. This means that when tropical cyclones reach land, they die out because they are cut off from the warm ocean waters that keep them going.

14. The Philippines is prone to tropical cyclones due to its geographical location which generally produce heavy rains and flooding of large areas and also strong winds which result in heavy casualties to human life and destructions to crops and properties.
