Chapter 7.3
Talas rages over Japan (part 1)

Slide 1 - Slide

G52 Wind

The moving mass of air is called wind
When the air moves quickly, the wind force is high. The invisible air particles can push really big trees over.

You can measure wind speed with a wind meter.

The Beaufort scale goes from 0 to 12. When the wind force is 0, the weather is calm (no wind).
When the wind speed reaches 12, there is a hurricane.

The aims of this paragraphe
Things you should know:
  • how hurricanes affect people, the economy and the landscape
  • the characteristics of a hurricane
  • the relationship between levels of development and the damage and number of victims caused by hurricanes
  • how to classify a hurricane according to the Saffir-Simpson scale (figure 12)



Slide 3 - Slide

Introduction
Hardly five months after the tsunami, Japan was struck by another natural disaster. Tropical Storm Talas raged over Japan.

G57 Hurricane

A hurricane is a heavy tropical storm with a wind force of at least 12 on the Beaufort scale. The storm forms above seawater with temperatures above 26.5°C. These high temperatures only occur at the end of summer, when the seawater has been warmed up. Hurricanes are enormous: they are between 500 and 1,500 km wide. A hurricane lasts between five and ten days on average.

Hurricanes occur mainly in the tropics. This is the region between the Tropic of Cancer and the Tropic of Capricorn on either side of the equator.

Slide 5 - Slide

G 58How hurricanes form
1. Warm seawater above 26.5 °C.

2. Hot, moist air rises and cools.

3. Large storm clouds form.

4. The air begins to spiral.

5. New air is ‘sucked in’ from the surroundings.

Slide 6 - Slide

Talas
Hardly five months after the tsunami, Japan was struck by another natural disaster. Tropical Storm Talas raged over Japan.
Japan's typhoon season ranges from May to October each year, peaking in August and September. 

Slide 7 - Slide

What is a hurricane?
  • A hurricane is a heavy tropical storm with wind speeds of more than 118 km per hour.
  • In Asia, a hurricane is called a typhoon.
  • a hurricane can leave many victims and cause serious damage.

Slide 8 - Slide

This scale begins where the Beaufort scale stops: at force 12.

Slide 9 - Slide

Three characteristics:
  • Hurricanes have extremely high wind speeds.
  • Heavy rainfall that causes flooding. It also 
causes landslides on hillsides.
  • The strong wind can cause 
high waves at sea. 

Slide 10 - Slide

Storm Talas
In 2011, between May and August, there were eleven tropical storms over East Asia, including four hurricanes.
There were warnings of a hurricane, but Talas did not reach hurricane force. Over land, the storm slowed down and it weakened further over the Sea of Japan, but the storm damage was enormous
Most of the deaths were caused by landslides.
