Hurricanes 101 | National Geographic


(heavy winds blowing) – [Narrator] Cyclone, typhoon, hurricane. All of these names are used
around the world to describe the most powerful storm known to man. Hurricanes are
unpredictable but scientists have a through understanding
of how hurricanes form and sustain their power. In the Atlantic Ocean,
hurricane season peaks during the late summer months when
tropical waters are the warmest. Hurricanes form from a
cluster of thunderstorms that suck up the warm,
moist air and move it high into Earth’s atmosphere. The warm air is then converted into energy that powers the
hurricane’s circular winds. These winds spin around
a low-pressure center called the eye. Which can provide a 20 to 30
mile radius of eerie calm. Encircling it is the eye wall,
a towering ring of clouds with some of the fastest
wind-speeds of the hurricane. Surrounding the eye wall
are curved bands of clouds. The rainbands, often tens of miles wide releasing sheets of rain
and sometimes tornadoes. When a tropical storm’s
winds reach at least 74 miles per hour, it becomes a hurricane. The hurricane then receives
the category ranking of one to five on the Saffir-Simpson Scale based on its wind speed
and potential damage. But wind speed isn’t always
the most dangerous component when hurricanes come near land. It’s storm surge. Storm surge is caused when
winds from an approaching hurricane push water towards the shoreline up to 20 feet above sea level
and can extend 100 miles. 90% of all hurricane deaths
are the result of storm surge. While hurricanes can
cause mass devastation, just like other natural disasters, they serve a higher purpose
within the global ecosystem. Hurricanes help regulate our
climate by moving heat energy from the equator to the poles keeping the Earth’s temperature stable. Over time, science has helped
us to better understand hurricanes and predict their paths. Saving lives through early warning systems and helping us build better infrastructure to protect our cities. The more we study these complex storms, the better we can prepare for them and minimize their impact on human lives.

  1. Hurricanes are unpredictable but scientists have a thorough understanding of how hurricanes form and sustain their power. What intrigues you the most about these powerful storms?

  2. Hurricanes can also cause tornadoes watch out for de there are also 3 hurricanes coming be on the lookout Florida's

    on the state of emergency right now

  3. Gary Larson addressed this kind of prediction problem.

    "Oh – oh. Rain squall's a – comin'… My knee is actin' up."
    "I'd sat more like a blizzard, judgin' by my hand here."
    "Well somethin's happenin'… There goes my head!"

  4. Here in Ohio we usually receive a good bit of rain from the Hurricanes. We have our own worries though with tornadoes. Been through one. Very scary.

  5. To all on the East Coast prayers for you guys. I live in the florida panhandle so I’ve been through this. Tie down stuff, turn fridge and freezer to coldest settings, be ready for spin up tornados, board up windows and doors, evacuate if you can and just ride it out if you have too. Nothing you can do about it.

  6. Is it true that Indian Ocean cyclones unexpectedly dropped to 0 per year beginning in 2008? Is there anything in our temperature data that shows a correlation between air and ocean temperatures and an increase in major storms? Will changes in the solar cycle lead to weaker or stronger hurricane seasons?

  7. I was in south Florida when Irma hit last year and our neighborhood looked like it had during hurricane experiences I’d had in the past, until around the same time a ton of water appeared in the neighborhood (storm surge) followed by maybe 10 minutes of eerie calm and then I noticed the direction which the trees were blowing switched directions. I recognized that the eye of the storm had passed over us. A first for me. Thankfully the water didn’t reach our house though our neighbors next door had water damage.

  8. Coincidence that we have an incoming super typhoon.

    Edit: Suprised how many are "egocentric" saying "I am expecting a typhoon" instead of "we". Not actually saying its bad. Just an observation.

  9. What unit is "KPH" ?
    In the International Unit System, the velocity unit is the meter per second (symbol : m/s) and a practical unit which is accepted is the kilometer per hour, the symbol of which is "km/h" (lowercase) and not KPH.

  10. 0:06 That's what the t-storm that ripped through Phoenix in 2010 looked like. I can't imagine getting hammered like that for several days.

  11. The impending danger video.Natural calamities are hard to prevent. “Discretion is the better part of valor.” I am interested in anomalous animal behavior before a hurricane.🌪🌧💨

  12. Hurricane Harvey hit pretty hard where Trump wants his wall built. I've never been to see a hurricane perform live, so forgive me for asking, but how much damage (repair costs) can we expect a wall like that to take in a hurricane region over the long run?

  13. Thanks to the YouTube ad that showed up in my feed I'll never buy another National Geographic….but then I stop buying them years ago anyway.

  14. I confess, both God & hurricanes frighten me… "Just as calamity is due to disobedience, so deliverance from calamity can be obtained only by obedience. There is no chance or uncertainty about the matter. Turning from God inevitably brings disaster, and turning to God as inevitably brings blessing." – Dr J.E. Esslemont, Bahá’u’lláh and the New Era

  15. 1:25 Actually, the Saffir-Simpson Scale is this:
    Cat 1: 74-95 mph
    Cat 2: 96-110 mph
    Cat 3: 111-129 mph
    Cat 4: 130-156 mph
    Cat 5: 157+ mph

  16. I feel really bad for people who live in Florida, Florida has the hurricanes, my friend in roblox had been in a hurricane warning, because she lives in Florida, but luckily it did not happen and she is safe, and I hope everyone who lives in Florida will be safe if they have been in a hurricane they are very dangerous

  17. In the name of Allah bless all day long life and today and tomorrow Allah bless all thank you so very very much Allah bless all thank you so very very soon best wishes for your help with this message was sent from Windows mail your account can do this world thanks again Allah bless all of the year again when you get the latest version of this world thanks again Allah love us Allah bless all of the year

  18. Hurricane modification was mentioned by NG in the ‘60s.

    Any modification tech news between now and then? Nearly 60 years later?

  19. Well just found out that west coast don't get any cuse the water is cooler over there and hurricanes get fuel from warm water smh

  20. Thank goodness for satellites 🌎💫🛰
    A warning for safety beats none at all
    Godspeed Sincerely from LarryWhittington
    May God bless all who've helped on a national holiday our Labor Day 🇺🇸

  21. Thanks to this 101 series.
    I don't know typhoon can maintain Earth's temperature until I watched this video.
    Hurricanes is not only a disaster bringer but also a ecosystem keeper.
    Although hurricanes had brought so many sorrow to human, but it is a necessary part for the Earth.

  22. I remember the typoon Yolanda in the Philippines it's so huge damage and so many people die and many structure are broke , Yolanda 220+ wind speed
