    i think he has this backwards since in the northern hemisphere cyclones typically have a west/northwesterly track. The veering should be to the left of the track and backing should be on the right as it is coming at you, making the south side of the example the navigable side and your center of the low should be somewhere between 100-135 degrees relative to the direction the wind is coming from.

      I know this is an old comment (and video) but i wanted to clarify it to any new viewer. Even if the storm is heading west (which you correctly state is the usual direction, while also curving north while in the northern hemisphere) the wind will still be veering on the dangerous semicircle (you can draw it out on a paper and will see it).

    Very good method of remembering. Thanks. Although, 'dangerous' depends very much on your vessel's stability. For example, an offshore/platform supply vessel (or other fine lined hullform) may become unstable (parametric rolling/free to trim KN problem) due to partial loss of buoyancy with a following sea. Hence, backing weather, heading cross atlantic, should be avoided. Better to be head on to weather in some cases.

    You are right about this the air moves inward and I drew it as going outward.

      yeah, you had my head “veering” on this one Neil ! Thanks so much for all. I have eight renewals, as you know, on my license. Over 12,000 days at C. I am still learning from you and happy I took your course!

      This is Mark, I’d love to drink some coffee with you and discuss how my confounded weather plays with the landmasses in Alaska. Also why in the Arctic, it blows 20 kn, and they think the world is coming to an end, and it momentarily dips down to 20 kn in the middle Aleutians and we breathe a sigh of relief!

    TRS generally moves from East to West direction after its formation....Before recurving around 20 to 25 deg latitudes, the Dangerous Semi Circle is towards the Poles (both in NH and SH)....In the dangerous semi circle you get sucked in towards the EYE of the storm and in the navigable semi circle, you get thrown away from the path of the storm (also dependent on your avoidance actions)...
    In your video, the storm is moving Easterly...which is a wrong path unless the condition is after recurving, but even then the movement is usually NE'ly in the NH and SE'ly in the SH (after recurving)

      he didn't say that it is right after the formation of a TRS or after recurving. But after implying that his example is of Northern Hemisphere, then his presentation is correct in all manners.

    Hi
    1.arrow showing outward...should be inward.
    2. You are showings a anti clock wise direction. That means northern hemisphere right so navigable semi circle should be left or down. But you are showing top ?

    hello sir, is it not this way.
    they usually travel Westerly then North Westerly in the northern hemisphere and South Westerly in the southern hemisphere.

  • @maui808jah

    The typhoons in the Pacific don't all spin counterclockwise. Only in the northern hemisphere does the storm spins counterclockwise but in the southern hemisphere, it spins clockwise

    • @Calqid
      @Calqid 10 месяцев назад

      Also, as I learned from. Bowditch and Chapmans when I was a kid, hurricanes in the Atlantic and Typhoons in the Pacific… but have you ever heard a Hawaiian call it a typhoon? Nope. Also, to really make things screwy, there occasionally exists an hurricane/typhoon/tropical cyclone in the Eastern Pacific Mexican coast!

    Ive read some stuff on the internet,, saying that the eye of the storm is calm,. Generally all of the navigators try to avoid it. I wish i could see a graphical representation, maybe the greatest ship going to the eye of a storm.,

    TRS generally track from East to West, not West to East. You also have your dangerous and navigable semi-circles the wrong way around.

  • @robray111
    @robray111 Год назад

    I think it should be reversed: You turn your BACK into the wind and not your FACE. How else are you going to get the High on your right and the Low on your left if the wind blows counterclockwise?

  • @Capt_sal_b777
    @Capt_sal_b777 6 лет назад +1

    Sorry Wrong definition : In the Northern Hemisphere, if a person stands with his back to the wind, the atmospheric pressure is low to the left, high to the right. This is because wind travels counterclockwise around low pressure zones in the Northern Hemisphere.

  • @Captain_Rover

    It’s wrong
    Right is in N hemisphere , observer stand with his back to wind low pressure is his left and high pressure is his right and north hemisphere its wind blows anti-clockwise

    Doesn't the TRS move east to west?

    • @SuperManishrockstar
      @SuperManishrockstar 7 лет назад

      In the northern hemisphere it moves between west and WNW & in southern hemisphere it moves W and WSW at a speed of 12 kts. Further it curves and recurves N and NE respectively in NH and curve to S and recurves to SE in SH

    • @marinesecondofficer520
      @marinesecondofficer520 3 года назад

      Was wondering the same! Due to Coriolis effect it should be moving from East to West as what i remember..

    You said if you facing the surface wind, on your right is low pressure, I drew low pressure on stickman right and then at 1:33 he is facing into low pressure. The horrible explanation for newbies. Clicking another video.
