Hurricanes (pp. 48—53)
- See glossary.
- A monsoon is six months of rain in the tropics.
- Tropical depression (rainstorm with winds of 38 mph (60 kph) or less), tropical storm (heavy rain and winds between 39—74 mph (60—120 kph), hurricane (very heavy rain and winds of 75 mph (120 kph) or greater).
- They both chase after dangerous storms, hoping to gather information.
- They have learned that most hurricanes form after the ocean water warms up past 80°F, so hurricanes are more likely to form during months when water temperatures are above this.
- The eyewall directly surrounds the center, or eye, of the storm.
- The falling barometric pressure in the middle of the mass of the hurricane causes the winds to increase.
- Typhoons; (Tropical) Cyclones [NOTE: The text incorrectly indicated ‘willy-willies’, which are equivalent to the phenomena that Americans refer to as ‘dust devils’]
- The rising ocean water on land (storm surge) causes 90 percent of the deaths.
- Extremely low air pressure inside the hurricane.
- The country is very flat, and there was no way to warn the people of Bangladesh because they did not have modern communication systems.
- Most were killed by touching downed electrical wires.
- It is a governmental agency that issues watches and warnings to the people of advancing hurricanes. They use the latest technology to do so.
- It has been able to give 24-hour warnings of approaching storms. The people are able to leave their homes to go to safer areas until after the storm has passed.
- When a hurricane draws near, Doppler weather radar tracks the storm’s details.
