VOCABULARY Eye: The calm center of a hurricane. Eye wall: The storm clouds near the eye
that produce a hurricane’s strongest winds and heaviest rains.
Levees: Natural or man-made walls that prevent rivers and lakes from flooding the land.
Storm Surge: Wind-driven wall of seawater.
Tropical Storm: A storm system with whirling winds of at least 39 but less than 74 miles per hour.
HURRICANE KATRINA When the storm made landfall, it had a
category 3 rating on the Saffir. Hundreds of thousands of people in
Louisiana, Mississippi and Alabama were displaced from their homes.
Experts estimate that Katrina caused more than $100 billion in damage.
WHAT HAVE HURRICANES DONE Hurricanes have led to killing 2 million
people over the past 200 years. In 1970, a cyclone Bangladesh and
killed over 300,000 people. New Orleans was flooded with 80% of
water covering it.
HOW HURRICANES FORM It is fed by the oceans heat and water
evaporating from the surface. Air swirls in to take its place. When warmed moist air rises and cools
off, it makes clouds.
HURRICANES CATEGORIZED Hurricanes are classified into one to five
categorized based on wind speed. There is a scale that rates hurricanes
called Saffir-Simpson Hurricane Scale. This scale was made by Herb Saffir and
Robert Simpson.
TYPHOON KAMIKAZE Kublai Khan sent an enormous fleet of
Chinese and Korean to attack Japan. Yet twice in 1274 and 1281, his fleet
were destroyed by Kamikaze. Kublai Khan’s fleet was one of the
largest the world has ever seen, with more than 140,000 sailors.
GETTING READY Be sure to secure your storage shed
and put it below ground. You should secure trash cans with
cables or chains stuck in the ground. You should also secure wood, metal,
and other hard materials.
NOAA HURRICANE HUNTERS They flown across U.S. and around the
world. Their airborne platforms are used to the
gathering of environmental and geographic data for scientific research.
They learn about hurricanes by going inside them eyes of hurricanes.
NEW ENGLAND HURRICANE 1938 3,000 ships sunk, 700 people killed,
9,00 homes destroyed. This caused widespread blackouts. This also caused innumerable trees
were felled, and 12 new inlets were created on Long Island.
WHO NAMED HURRICANES The World Meteorological Organization
develops a list of names the are listed in alphabetical order.
They usually put tropical storms as that are discovered in each hurricane season.
Names can be repeated after an interval of six years, but the names of especially severe storms are permanently retired from use.
HURRICANE WATCH OR HURRICANE WARNING Hurricane warnings indicate that
hurricane conditions(sustained winds of 74 mph or higher) are expected somewhere within the specified area.
A hurricane watch means that hurricanes conditions(sustained winds of 74 mph or higher) are possible within the specified area.
The both warn you so you can get prepared.
WATER The ocean waters must be warm
enough at the surface to put enough heat and moisture into the atmosphere.
The overlying atmosphere to provide the potential fuel for the thermodynamic engine that a hurricane becomes.
The atmospheric moisture from the sea water evaporation must combine with the heat and energy to form the powerful engine needed to propel a hurricane.
WIND When vertical wind shear exists, the
hurricane’s rotational wind field may tilt with height.
In the tropics, where hurricanes form, easterly winds called the trade winds steer a hurricane towards the west.
In addition to the steering flow by the environmental wind, a hurricane drifts in the northern hemisphere due to process called beta drift, which arises because the strength of the Coriolis force increases with latitude for a given wind speed.
