Typhoon Haiyan

  1. 1. Typhoon Haiyan (Yolanda) By Mynn Kang & Jonathan Bakken Strawburrie Cake © Mynn Kang, 2014 : ))
  2. 2. Background Information On Typhoons (Hurricanes) Hurricane season in the Atlantic is between June and November. Hurricane season for the Eastern Pacific is May through November. To be considered a typhoon (hurricane), it must have wind speeds of at least 119 kph. In the western part of the North Pacific ocean between 180° and 100°E), a hurricane is called a typhoon. A typical typhoon (hurricane) is 600 km across.
  3. 3. What Causes the Storm Scientifically? Warm moist air over the ocean rises up near the surface causing an area of low air pressure. Air with high air pressure pushes into the area with low air pressure and changes the low pressured air into warmer and moister air that rises as well. As the air continues to rise, the temperature decreases and forms clouds. The system of clouds and wind grows and spin, fed by the oceans heat and water that evaporates. Storms north of the equator spin counterclockwise, while storms in the south spin clockwise. The difference in the rotation is caused by the Earth’s rotation on its axis. As the storm system rotates faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flows down into the eye. When the winds in the rotating storm reach 39 mph (63 kph), the storm is called a "tropical storm." And when the wind speeds reach 74 mph (119kph), the storm is officially a "tropical cyclone," or hurricane. Tropical cyclones usually weaken when they hit land, because they are no longer being fed by the energy from the warm ocean waters. However, they often move far inland, dumping many inches of rain and causing lots of wind damage before they dissipate completely.
  4. 4. When Did Typhoon Haiyan Happen? Typhoon Haiyan (Yolanda) formed November 2, 2013 and dissipated November 11, 2013. It struck the Philippines on November 8, 2013.
  5. 5. Where Did Typhoon Haiyan Hit Hardest? Typhoon Haiyan (Yolanda) affected Southeast Asia; particularly the Philippines and parts of Vietnam and China as well. Potato
  6. 6. How Severe Was Typhoon Haiyan (Yolanda)? Typhoon Haiyan had peak gust speeds of 379 kph (Kilometers per hour) while having a sustained wind speed of about 250kph. It was a category 5 typhoon. (In order to be classified as a category 5 typhoon, it has to have wind speeds over 251 kph.)
  7. 7. How is the Severity Measured? It is measured on the Saffir- Simpson scale from 1-5 based on wind speed and how much damage was caused.
  8. 8. How Much Damage Was Caused? 160,000 buildings were destroyed from Typhoon Haiyan. 384,000 acres of land was destroyed. Typhoon Haiyan dealt damage worth $1.5 billion USD.
  9. 9. How Many Casualties Were There? Typhoon Haiyan: Killed over 6,000 people. 1,800 were reported missing. 27,000 people were reported injured.
