SCIENCE 8 Let’s Recall! Can you answer: What is an earthquake? What are the types of seismic waves? How is magnitude different from intensity of an earthquake? TYPHOON Lesson Objectives At the end of this lesson, the students should be able to: describe a typhoon; explain how typhoons are formed; illustrate and describe the parts of a typhoon; and explain the effect of landmass and bodies of water to typhoons. INDIVIDUAL ACTIVITY INDIVIDUAL ACTIVITY INDIVIDUAL ACTIVITY LET’S DISCUSS! Typhoon  A weather phenomenon described as a storm with winds swirling around the center that occurs in the western pacific ocean. LET’S DISCUSS! What’s the difference between typhoon, hurricanes and cyclones? LET’S DISCUSS! How are typhoons formed? INDIVIDUAL ACTIVITY All the heat and air flow toward the eye creating the typhoon. The thunderstorms convert the moisture into heat. The heat causes more air to flow to the center of the storm causing evaporation. Typhoons start from tropical thunderstorms. The strong winds pull in the moisture from the oceans. INDIVIDUAL ACTIVITY All the heat and air flow toward the eye creating the typhoon. The thunderstorms convert the moisture into heat.

The strong winds pull in the moisture from the oceans. LET’S DISCUSS! LET’S DISCUSS! Low altitude winds is also needed to form a tropical cyclone. The air becomes warm, expands and rises. LET’S DISCUSS! Rising air cools, condenses and forms huge clouds in the troposphere. LET’S DISCUSS! As the air rises faster and faster, to fill the low air pressure, more warm air is drawn of from the sea and sucking cooler air downward. LET’S DISCUSS! The force created by the Earth’s rotation on a tilted axis causes rising air to spiral around the center.  cold Colde Warm air r air cools sinks down Warm air rises Low- altitude warm winds Warm ocean- 26.5 °C INDIVIDUAL ACTIVITY Draw a model of typhoon based from what you see on TV News or images from the internet. Then, label its parts based on its description below. 1. Eye- the center of a Typhoon described as a low pressure area. 2. Eyewall- bands of clouds surrounding the eye. 3. Rain Bands- arms of a typhoon characterized rains and winds weaker than the eyewall. LET’S DISCUSS! EFFECTS OF LANDMASS AND BODIES OF WATER TO TYPHOON If the typhoon makes landfall on a mountainous landmass the forced vertical ascent of air due to the mountains can result in huge amounts of rain, maybe several feet in one or two days. LET’S DISCUSS! EFFECTS OF LANDMASS AND BODIES OF WATER TO TYPHOON In a very general sense, typhoons gain power as they move over warm bodies of water and start losing energy once get over cold water. LET’S DISCUSS! As typhoon moves over a landmass, it weakens. If it moves over a warm body of water, it strengthens. LET’S SUMMARIZE! (1)_______ is a storm with winds swirling around the center that occurs in the western pacific ocean. The formation of a typhoon starts with a large body of water with a temperature above (2) ___. The (3)_____ is the center of a Typhoon described as a low pressure area. Its (4) _______ is characterized by bands of clouds surrounding the eye. While (5) ______ are recognized as the arms of a typhoon characterized rains and winds weaker than the eyewall. LET’S DISCUSS! As typhoon moves over a landmass, it (6)_______. If it moves over a warm body of water, it (7)_________. Checkpoint!!! ```` How much did this Fair Better Best lesson help you… (5 points) (8 points) (10 points) describe a typhoon; explain how typhoons are formed; illustrate and describe the parts of a typhoon; and explain the effect of landmass and bodies of water to typhoons.
