Ocean & Atmosphere – Coriolis Effect, Part I

In this segment, we explore the oft-misunderstood Coriolis effect, the apparent deflection of moving objects due to the rotation of the Earth beneath them. It’s not true that toilets in the southern hemisphere spin in the opposite direction as toilets in the northern hemisphere and here we’ll find out why.

For 62 years, the School of the Americas at Fort Benning, Georgia, has trained some of the worst human rights abusers in the hemisphere. From Pinochet’s soldiers in Chile, D’Aubuisson’s death squads in El Salvador, Banzer’s minions in Bolivia, Galtieri’s operatives in Argentina and Rios Montt’s soldiers in Guatemala to the present-day generals responsible for the coup in Honduras and the drug war killings in Colombia, the School of the America has a dark legacy. Renamed the Western Hemisphere Institute for Security Cooperation, the school has graduated 65000 soldiers from 18 countries. This weekend, tens of thousands of activists will converge at its gates to demand an end to the militarization and the massacres, the human rights violations and the secrecy… and fight to close the School of the Americas.

    so… if I throw a ball from the south to the north, the ball will shift to the left and if I throw it from the north to the south, the ball will shift to the right.
    Logicaly that means that if I throw a ball from east to west, the ball will travel more and faster, and if I throw the ball from west to east it will travel slower and not as much.

    The earth goes clockwise, the clip has been flipped when recorded.. :o (

    Good video – thank You for simple explaining.

    Got my officer’s exam tomorrow (merchant navy) – meteorology subject, that is.

    Once again – thanks for help ; )

    @marrrmar1 if you viewed from above the earth then the you’ll see the cloud move right. and if you viewed from below the earth then you would see the movement left. Hence North/ Southern Hemiphere

  5. Likeafoxow says:

    @marrrmar1 imagine standing in either the northern or southern hemispheres and then watching how the clouds move. if you stand in the northern, the cloud appears to be going south towards the west (right). if you are in the southern, the cloud appears to be moving north towards the west (left). you have to try to imagine standing on the earth while youre watching these clouds…

  6. iamafish400 says:

    I understand most of it but I don’t get the bottom 2 diagrams at 9:30. Why when the cloud is moving northwards in the Northern hemisphere does it still appear to be moving to the right? It makes sense in my head that it would be going to the left in that situation. Sorry if this makes no sense but I need to understand this :/

  7. Freedomfoe07 says:

    THIS HELPED!!! Thankyou!!! Now I can do my speech :D

  8. seanmac1990 says:

    @marrrmar1 The word Left is relative to the direction your facing.

  9. Sn0wFreak says:

    @ineverfakejumps thats what i am thinking

  10. Boxxxed says:

    Why is there a greater coriolis effect when the velocity of moving object is greater. If it takes less time for the object to move then there is a greater ratio of object speed to earth rotation speed and thus the rotation would have less effect on the displacement of the moving object. If it takes 0.00001 seconds for an object to move from A-B the slow rotation of the earth should have minimal effect? If it takes 12 hours for the object to move it would be 180 degrees long from its destination.

  11. Boxxxed says:

    I would post a site with good animations but I can’t post any links

  12. lexmark666 says:

    @marrrmar1 – If you were in the Northern hemisphere facing South, then the cloud would look as if it was moving to the right and vice versa.

    I think that’s what he meant. I’m trying to explain this to myself as well as you.

  13. marrrmar1 says:

    THEY BOTH LOOK LIKE THEY’RE MOVING TO THE LEFT
    WHY HAS NOBODY EXPLAINED THIS?!?!?!?!?

  14. SooRandom01 says:

    You are my hero … Thank you so much

  15. Johannady says:

    i am not sure.. can you tell me if i am right?
    it’s like if you draw a clockwise swirl.. and you are standing up on the north..
    it will look clockwise.. and if you are on the southern hemisphere you are upside down..
    but you don’t feel like you are because of gravity.. so it looks like it is going counter clockwise..

  16. ineverfakejumps says:

    If a cloud was moving south while in the southern hemisphere, wouldn’t the Coriolis effect still deflect it to the right? Why left?

  17. Flexelek says:

    Really nice vid, well done mate. Gonna have my state final exam on the 9th, in geography. Atmospheric studies were like 4 years back, this really refreshed my memory. The thing the other videos miss is the latitude speed component. Moevement of clouds going towards the equator is easy to understand, but going towards the pole is a bit different, and the starting velocity is the key.

    Again, big thumbs up. Keep em coming :)

    this guy is a hero, cheers man.

  19. rgsgt says:

    boom diggidy. now i’m ready to take my midterm

  20. domyaska says:

    thanks a lot for sharing this explanation!

  21. ShannonMarie0121 says:

    i wish you were my science teacher. this video was very helpful

  22. scxq28 says:

    The eastward component of an object at the equator is faster than anything north or south. So as the cloud moves north, it moves east faster than the Earth spinning beneath it.

  23. doomsword86 says:

    What I still don’t get is why cloud would appear to curve to the East when heading North in the Northern Hemisphere. If the Earth is rotating toward the East shouldn’t it appear to be curving to the left when going North? I’m guessing the answer to this question would require a more thorough explanation?

  24. ZiePe says:

    … Finally the german wikipedia page states that the CE also effects trains in a way that the right rail (n. hemisphere) sustaines more pressure than the left one. This can’t be the case if the CE? is a purely “optical” effect… right?

  25. ZiePe says:

    Well, although this is better than any other explanations on youtube, it must be very simplyfied: I get why the objects moving towards the equator appear to? drift to the right in the north and to the east in tje south but shouldnt it be the opposite (left-north/right south) when objects are moving away from the equator? Plus, I dont get why objects moving on the east-west axis are effected.

    @cadu1995 because you’re an idiot

  27. benmcfee says:

    @cadu1995
    See, I wouldn’t trust any of them, because unbiased News is a nearly impossible thing to achieve. But, the info that RT puts out has consistently proven more reliable than any of those others. I really am sorry to split hairs, and I’m sure you didn’t mean it this way, but I feel like part of the problem we face, is that too many of us are looking hard for someone to trust: a news source, a politician, a business model, etc, and we get screwed. Politics isn’t about trust, but distrust.

  28. lastofthetribe says:

    This is, yet again, another attempt by Russia Today, the Russian Government funded propaganda wing, to cause mistrust and confusion in the United States. Don’t let this affect your judgement. It’s propaganda. paulmbrownDOTblogspotDOTcom

  29. phillipgaley says:

    @cadu1995 Because NY Times, CNN and MSNBC are controlled from the Kremlin; you can figure that out—can’t you?

    @cadu1995 mabie while they dig up nagasaki and hiroshima they can look into the rape of nanking?

    @wisepizza he raised there funding

  33. YSKite says:

    This fuckers are killers, terminators.. they need to be shutdown. Good job RT.

  34. wisepizza says:

    And exactly what is the kenyan doing about this abomination?

    Operation Gladio.

  36. EvesNaughty says:

    @robi2000 Do some research before you say anything. It is a more intelligent way to begin a conversation. Every government is corrupt beyond belief. US is not different. The politics of this country creates, fuels, funds and sustains most genocides and wars. I can recommend a lot of material for your viewing. Thank you for your reply.

  37. robi2000 says:

    @EvesNaughty you really think that this school teaches ‘rape, torture and slaughter of innocents’ just because you just heard it on RussiaToday- the government funded news agency from Russia ? A country which thrives on corruption?
    RT is laughing at you.

  38. robi2000 says:

    at :40 seconds he says – ‘my neck was in the hold of this guy’
    and the guy (not American) says he went to school in the US?? Who’s ‘this guy’ ???
    Yes RT, you’ve done it again. More blaming of the usa for the unproven crimes of those you cannot even identify or call by name. Such tabloid propaganda

  39. EvesNaughty says:

    Our government just keeps shocking and seems there is no end in sight. Cutting after-school programs where children can learn to explore their creativity in true beauty, to discover their artistic potential and talents, in order to become well versed, well rounded, well educated free-thinking co-creators of our universe in order to further assist humanity in our quest for spiritual evolution…while funding the school of rape, torture and slaughter of innocent, defenseless people. Hmmm…AGENDA?

    @GuitarGirlWA Yeah you go girl. That’s my girl.U got the idea honey.

  41. GuitarGirlWA says:

    @cadu1995 yes I know :( It is not just America though… I could name some others that should be charged… say Israel?

  42. cadu1995 says:

    @GuitarGirlWA Got cha. look at my page & see how America Attacks itself & does the cruelest crap to people in this world just as much if not more than russia or china.
    ONLY NATION to use NUCLEAR WEAPONS on an enemy not once but TWICE because they wanted to scare Russia & test their 2nd “different” weapon on Nagasaki.
    Should have been brought up on CRIMES AGAINST HUMANITY-Japan already LOST the war-there was no need for that destruction of humanity.

  43. GuitarGirlWA says:

    @cadu1995 The part in which I was always told “RUSSIA IS THE ENEMY”

  44. ed11561 says:

    @CokesnortinFreemason WHATdoesn’t make any sense? Do you always comment making no sense whatsoever?

  45. cadu1995 says:

    @GuitarGirlWA What part is ironic hey?

  46. cadu1995 says:

    @KidVicious541 Maybe because it’s based in WaSHINGTON -DC?

  47. KidVicious541 says:

    @cadu1995 Why is “Russia Today” in perfect English..?

  48. GuitarGirlWA says:

    @cadu1995 ironic hey.
