Buys Ballot Law and Avoiding the Center of a Low Pressure System

[@roberts2554]

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.

[@Robinson_Crusoe]

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).

[@AnishMohandas]

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)

[@ryanpinohermoso5419]

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.

Thank you very much your comments are appreciated.

[@scottcampbell26]

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.

[@nezu4404]

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 ?

[@uscaptainstraining]

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

[@Calqid]

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!

[@Calqid]

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!

[@seamonk.]

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.

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]

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!

This guy help me whole week assignment….

[@stldrew2137]

Really appreciate these videos. Thank you for taking the time to load these up, they’re helping a lot.

[@juliusstuff]

yes it is right and thanks. hope you have some lectures about seamanship stability and trim. you really did a good lecture and well explained.

[@williammalapitan]

Free Lessons that are actually helpful and understandable.

[@mca1901]

the point is wind coming where 😅 thank you ❤🎉🎉🎉🎉❤

[@Kormondre]

what an amazing teacher

[@robertsantos9330]

I'm watching this video over and over like straight into my subconscious.

[@kimseymour8896]

Good job keep it up we’re getting it slow but sure, but we’re getting it

[@aphrodence02]

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.,

[@johngnanavelu152]

EVEN I WAS THINKING THE SAME...I HAVE BEEN SEEING ALL HIS VIDEOS AWESOME

[@jcm06]

was this recorded reverse?

[@captainphil2023]

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

[@Capt_sal_b777]

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.

[@shishirkanaujia]

its facing the wind not standing with back yo wind

[@johnpaulpineda7436]

how about in southern?? where is the low pressure and the high pressure??

[@mrludopa]

you are very good teacher, i love your lessons

[@rafaelmelo1615]

i like your memorization techinics. Do you have a website with this material ?

[@williammalapitan]

Oh no. Plss keep it free in youtube.

[@robray111]

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?

[@yasyas1]

Great b instruction

[@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

[@nguyenhieule8767]

YOU WERE WRONG JUST THINK ABOUT IT, THE ABOVE EXPLAINATION IS THE SAME FEARURE AS THE BALLOT'S LAW

[@ankittanna87]

Doesn't the TRS move east to west?

[@SuperManishrockstar]

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]

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

[@spiritexpeditions]

Very helpful! Thank you!

[@OLRACSOMAR1]

the cycle is also not outward, it must be inward

[@scottcampbell26]

*voyage east to west for example.

[@secondofficerashishsharma9191]

Thanks sir , find helpful

[@jmans25]

good video, helped me as a cadet with ground school.

[@jmans25]

my instructor taught us the law, but never explained it. Thanks ;)

[@skateDSH]

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.

[@mjbyrne1153]

Your hoody rules. Lol.

[@Stichting_NoFa-p]

you pronounce Buys Ballot totally wrong.

[@gouravbhowmick8599]

totally wrong explanation
