    One other jarring part about being under the eye of a hurricane is that after the eye passes, the wind is blowing in the opposite direction from before the eye. This can blow debris back over where people were hiding, and it means anyone who was hiding must relocate to the opposite side of the structure to shield them from the reversed wind

    I live in Florida and I've twice been in the eye of a hurricane. And even though one shouldn't, I briefly went outside to experience it. It was extremely still and quiet, and surprisingly warm. I remember a slightly golden hue to the sky. Beautiful, but eerie.
  • Air isn't just 'like a fluid', it is a fluid! Liquids and gasses both are.
  • @VividBoricua
    I appreciate the attention to detail in the initial photo at 0:24. The wind is blowing in the opposite direction as it should!
  • @tgypoi
    An older friend told me they used to have cyclone parties, stay inside partying while the storm raged, run outside for the eye, then back inside for the other side. Sounded like fun, but I've always just avoided being in bad storms.
  • @zcarp8642
    The one thing you should ALWAYS remember. Be hesitant when there's a violent storm and it suddenly calms down. Weather is fickle and can easily turn from beautiful back to cruel
  • @MagnakayViolet
    The most exciting scene from 'The Day After Tommorrow' film was when the characters experienced the terror of the eye of the super blizzard bringing super cold air from the highest layers of the atmosphere to the ground, causing things to freeze dangerously.
  • 0:00 They even made the wind blow in the other direction, which is clever because after the eye, the wind will go in the opposite direction as before the eye, or if the eye misses you, the wind will go in one direction, then during the most severe point it will go perpendicular to the direction before, then when it starts to weaken it will go opposite the original direction

    I remember when I was in Okinawa we would have BBQ cookouts in the eye of the typhoons. Typhoon parties were so much fun.

    Air doesn’t just act like a fluid. It IS a fluid.
  • @Sparkle8205
    I remember when Hurricane Sandy hit where I lived, it started getting bad when I was at my neighbor’s house across the street, and had to stay over due to the hail and whatnot, and once we were over the eye, I managed to run back home before it got bad again.

    Eye am blown away. Glad we don't see those in Poland.
  • @lukeguillow
    It is a very interesting thing to experience. We had the eye of Hurricane Floyd in ‘99 come right through our campus. Very very cool.
  • Another reason the eye might be so calm is that it’s close to the center of rotation, and when something spins, the middle moves slower than the rim, but with hurricanes this is usually the opposite, where the fastest winds are found near the center, the outside is usually pretty gentle, however, this is because all the air in the hurricane wants to move into the center, but as it migrates to the center of the hurricane, the Coriolis effect causes the air to drift to the right if it’s in the northern hemisphere or to the left if it’s in the southern hemisphere, causing it to miss its target, the air keeps trying to pull in though so at its closest point it begins to curve in the direction that the target is now, but centrifugal forces will cause it to not get any closer so instead it gets flung away from the center, so it makes an attempt again, but this time in addition to the Coriolis effect, it now has some rotational momentum making it miss even further, this repeats until it is in a stable cycle with air trying to pull into low pressure in the middle and centrifugal forces pushing it outward which causes the air to “orbit” the center and it basically is an orbit, the only difference between this and planets orbiting a star is with planets orbiting a star the centripetal force is gravity, where in hurricanes it’s the low pressure in the eye, and with planets, the closer a planet is to its star, the faster it has to spin around the star to remain stable, the same applies for hurricanes, but the air in the eye is where it wants to be, so the only rotation in the eye would be air dragged along by the eyewall, but it’s so close to the center that everything is orbiting that the same rpm of the air has lower windspeed. And actually, because the eye is has the lowest pressure in the hurricane, when in the eye, most of the effects of the storm cease temporarily except for one, storm surge, because storm surge is caused by the low pressure and the eye has the lowest pressure in the storm, storm surge is at its worst when in the eye
  • @nicksamek12
    Do hurricanes leave any evidence of their passing in the geological record? Or are they relegated to records in trees?
  • @Xelaria
    Good to know, I’ll keep an eye out for them.
  • @windywendi
    Fun fact hurricanes and typhoons are basically the same thing, just depends on where they happen!
  • @Darky9741YT
    "The eye keeps us from being blind" that got me rolling on the floor🤣🤣🤣🤣
