How a Hurricane Forms
  • Hurricanes form in the tropics where the water
    and air are warm and moist. There are many
    factors which need to be just right in order for
    a hurricane to form. Scientists aren't sure why
    all these factors are needed but know that they
    are important. A study found that out of 608
    possible storms only 50 developed into
  • Tropical storms.

How a Tornado Forms
  • A tornado begins in a severe thunder storms
    called a super cell. A supercell can last longer
    than a regular thunderstorm. The same property
    that keeps the storm going also produces most
    tornadoes. The wind coming into the storm starts
    to swirl and forms a funnel. The air in the
    funnel spins faster and faster and creates a very
    low pressure area which sucks more air (and
    possibly objects) into it.

Where Are Tornadoes Located
Tornadoes are located all over the world!  The
winds can go up to 300 miles per hour! The United
States has the most tornadoes in the world, about
800 per day.  In the United States, tornadoes
occur in all 50 states!  Every state has just
about 1 to 10 tornadoes a year.  A tornado is a
highly concentrated vortex of winds that occur in
thunderstorms. Tornadoes cause billions of
dollars in damage and kill about 50 people each
year!

Keeping Track Of A Tornado
  • Chasing storms was first done by scientists to
    study the thunderstorm environment. Little about
    the dynamics and physics of thunderstorms, as
    well as lightning, is well understood yet, so in
    the interest of research storm chasing is
    necessary to keep track of and investigate a
    storm and watch it go through its lifecycle

The Lives Lightning Takes
Lightning kills more people each year than
tornadoes and hurricanes, making it the second
most frequent weather-related killer in the
United States.

How Do Thunderstorms Form ?
Thunderstorms are formed by the uplifting of warm
and humid air. There are many factors that lead
to the uplifting of air, for example, solar
heating in the vicinity of low pressure troughs
when two different air streams meet or when air
is forced uphill.
14
Thunderstorm Damage
The white puffy clouds that have been growing all
day are replaced by a greenish sky. A distant
rumble is heard...then another. It starts to
rain. A flash of light streaks the sky, followed
by a huge BOOM. Welcome to a thunderstorm.

Wilma destroys homes
  • Wilma has destroyed a lot of homes. Roof tops
    have been lifted from hurricane Wilma. There were
    a lot of floods .

17
Striking Lightning facts
  • Lightning is essentially a gigantic electrical
    spark that results from billions of volts of
    natural static electricity. Lightning is usually
    associated with thunderstorms and rain.

How To Prepare
  • A natural disaster can happen at any time. Some
    disasters give warning like a storm preceding a
    flood.  Others, like earthquakes give no
    warning.  Once a disaster happens, the time to
    prepare is gone and all you can do is cope.  Take
    the next few minutes to examine what you can do
    to prepare.  Anything you do today to will be
    like making a deposit in your survivability
    savings account for withdrawal in tough times.

Hurricane Andrew
  • Hurricane Andrew was a small but powerful storm
    that caused massive destruction along a path
    through southern Florida and south-central
    Louisiana in late August 1992 (fig. 57). Rainfall
    associated with Andrew was light for a hurricane
    because of the small size and rapid forward
    movement of the storm. However, rainfall totals
    of more than 7 inches were recorded for the storm
    period in southeastern Florida and Louisiana a
    high of 11.9 inches was recorded in Hammond, La.
    (Rappaport, 1992). Maximum sustained windspeeds
    of 141 mph (miles per hour), with gusts of 169
    mph, were recorded on August 24, just before
    landfall in Florida (Rappaport, 1992). A storm
    surge of about 17 feet above sea level was
    recorded at Biscayne Bay, Fla. (fig. 58) and
    about 9 feet near Terrebonne Bay in south-central
    Louisiana (fig. 59).

33
The Damage Hurricane Andrew Caused
  • More than 250,000 people were left homeless
    82,000 businesses were destroyed or damaged
    about 100,000 residents of south Dade County
    permanently left the area in Andrew's wake.
    Andrew also had a severe impact on the
    environment -- it damaged 33 percent of the coral
    reefs at Biscayne National Park, and 90 percent
    of South Dade's native pinelands, mangroves and
    tropical hardwood hammocks. It also created 30
    years worth of debris.

34
Hurricane damage
  • Only three category-5 storms have hit the United
    States since record-keeping beganthe 1935 Labor
    Day hurricane, which devastated the Florida Keys,
    killing 600 Hurricane Camille in 1969, which
    ravaged the Mississippi coast, killing 256 and
    Andrew in 1992, which leveled much of Homestead,
    Fla. Hurricane Katrina in 2005 was a category-5
    storm at peak intensity over the central
    Caribbean, Mitch in 1998 was a category-5 storm
    at its peak over the W Caribbean, and Gilbert in
    1988 was a category-5 storm at its peak. Gilbert
    was the strongest Atlantic tropical cyclone of
    record until Wilma in 2005, which was at its peak
    while category-5 storm over the W Caribbean. The
    1970 Bay of Bengal tropical cyclone killed about
    300,000 persons, mainly by drowning. The
    deadliest U.S. hurricane was the 1900 Galveston
    storm, which killed 8,00012,000 people and
    destroyed the city.

35
Tornado Damage
  • FEMA has found that enhancing construction
    minimizes property damage to homes in areas prone
    to hurricane force winds, and those same
    techniques can be just as effective in guarding
    against damage from moderate to severe tornadoes.
    Also, proper construction techniques and
    materials based into existing construction to
    reduce the damage on the most current model
    building codes can be used in both new
    construction and from low to moderate intensity
    tornadoes

36
The Lives A Hurricane Takes
  • Forecasters said Dennis was following a
    northwesterly track through the Gulf of Mexico
    where 116 oil platforms and rigs have been
    evacuated. It is expected to make landfall
    somewhere between western Florida and Louisiana
    late Sunday.Before Dennis' arrival, Cuban
    authorities had rushed more than 700,000 people
    into shelters overnight, including at least 2,500
    foreign tourists

37
How Lightning Forms
  • Lightning is an electric current. Within a
    thundercloud way up in the sky, many small bits
    of ice (frozen raindrops) bump into each other as
    they move around in the air. All of those
    collisions create an electric charge. After a
    while, the whole cloud fills up with electrical
    charges. The positive charges or protons form at
    the top of the cloud and the negative charges or
    electrons form at the bottom of the cloud. Since
    opposites attract, that causes a positive charge
    to build up on the ground beneath the cloud. The
    grounds electrical charge concentrates around
    anything that sticks up, such as mountains,
    people, or single trees. The charge coming up
    from these points eventually connects with a
    charge reaching down from the clouds and - zap -
    lightning strikes!

38
The Damage Lightning Causes
  • The odds of being struck by lightning are
    approximately one in 600,000.  The odds of
    winning the lottery are about one in five
    million.  However, lightning causes as many as
    100 deaths and 300 injuries in the United States
    each year.  A problem with the statistics on
    lightning is that the numbers we receive are only
    those seriously injured or killed by lightning. 
    Seventy-five percent of those struck by lightning
    survive.  They may suffer from heart damage,
    inflated lungs, brain damage, loss of
    consciousness, amnesia, paralysis, and burns. 
    Not all cases of lightning strikes are
    disastrous, either.  Some blind and deaf
    individuals struck by lightning have reported
    their senses being restored after their
    encounters.  By following all safety precautions,
    one can reduce the probability of being struck by
    lightning and the number of lightning casualties
    can be reduced.  One must take the responsibility
    for his or her safety and take appropriate action
    when threatened by lightning.

39
Destroyed Houses From Lightning Storms
  • Fire officials believe a lightning strike around
    1030 p.m. Wednesday, June 4, sparked a fire that
    completely gutted a Payne Road home. The house
    was unoccupied at the time.
  • Block Island volunteer firefighters battled the
    fire for over three hours at the cedar-shingled
    summer home of John Cassidy, amid heavy rain,
    crackling thunder and a lightning storm.

40
Hurricane Katrina Survivors
  • The American Red Cross is where people mobilize
    to help their neighborsacross the street, across
    the country and across the worldin emergencies.
    The American Red Cross, a humanitarian
    organization led by volunteers, guided by its
    Congressional Charter and the Fundamental
    Principles of the International Red Cross
    Movement, provides relief to victims of disasters
    and help people prevent, prepare for, and respond
    to emergencies. You can help ensure that the Red
    Cross can continue to provide these lifesaving
    services and has the resources, talent and
    ability to continue to deliver them by making a
    donation to support all of its cores services
    today.

Tornadoes taking lives
  • EVANSVILLE, Ind. -- Dan McDonald, a firefighter,
    raised his ax and plunged it into the carcass of
    a mobile home, looking for life but
    half-expecting to find more death. It was a dozen
    hours after a rare November tornado hop scotched
    across southwestern Indiana, snapping trees,
    obliterating trailers and killing 23 people.

About Lightning
  • The early Greeks thought that the king of the
    gods ,Zeus , hurled thunderbolts from stormy
    skies .Lightning can go speeds up to 60,000 miles
    per second 6,000 times as fast as a spaces About
    Lightning hip. Also a flash of lightning is
    brighter than 10,000,100 watt light bulbs. About
    100 lightning bolts hit the Empire State Building
    each year and every second of the day 100 more
    lightning bolts hit the earth . Lightning can
    also be different colors like purple, red, green,
    pink, blue, but the most popular color is white.

Different Types Of Lightning
  • Heat lightning comes when it is hot outside.
    Sheet lightning looks like flat waves. Ribbon
    lightning looks like streamers floating in the
    sky the sky. Silent lightning is so far away that
    you can hear it. Finally, ball lightning seems to
    be a bright round spark that float in the air.

A New Kind Of Lightning
  • In 1995,scientists discovered a new kind of
    lightning and named it elves. Elves is a short
    bright flash of lightning which blaze forth high
    above the cloud at the edge of space. Elves last
    for less than a thousandth of a second. Know one
    is absolutely sure what they look like but in
    therein they are green.
