Barotropic v. Baroclinic Conditions
Переглядів 17 тис.4 роки тому
We first look at the differences between barotropic and baroclinic conditions in the ocean, and then apply that to an example of a section of the Gulf Stream in the narrowest parts of the Straits of Florida.

15:12 You repeatedly said; Temperature controls density. How about pressure, please?
thank you
thankyou proffesor🫡
❤ nice lecture ❤
Dear Tamara Barriquand, Thank you so much for all your videos. It is very easy to understand all those concepts with equations. You are an excellent teacher. :)
Where do i find the textbook referenced?
thank you! this really helped me visualize the complex forces at work here.
thank you!
the courses is nice for me !!! please could you share the coureware...
Thank you!
Professor, you saved hours!
canary current is a cold current, so its density will be higher, but still, it covers a shallow depth? why is it so?
Thanks mam learn alot from here ❤
Hi Tamara! Your videos are really helpful :), why is it that we only consider the vertical component when it comes to vorticity?
Hi Tamara! Could you teach us about geopotential hight related with isobarics surfaces?
Yes it would be really appreciated!
I don't understand why the density of A and B are the same in the barotropic flow(06:44), isn't that A and B are in the different isopycnic lines?
thank u professor, I finally got it!!!
Maam, Can you tell me what if Geostrophic wind's path if coriolis parameter was going towards right in the NH?
As the Oceans shutdown, vulnerability to carbon-forcing grows weaker, and if we halt carbon emissions now that the AMOC is shutting down, the cold will be over-compensating. We are already in the first stages of the cooling correction effects of the modern warming in the last century--a Dansgaard-Oeschger event. Every 4th "DO" cycle (every 6000 years) there is an amplified event much more extreme--the Heinrich event. That is happening NOW in a Micronova. Shutdown of the AMOC. We are already at the beginning of an Ice Age. More details in my 2nd book, "Surviving the Micronova."
Very nice lecture, thanks a lot for sharing this
Mam u make amazing videos...ur videos make me love with my subject oceanography..u can explain difficult things in a very easy way. please upload new videos too.
can you apply this to the atmosphere in the same way as you do apply it to the ocean?
Thank you for the very nice lesson 😊
Tamara, I really like your class so much! thank you so much for sharing these.
Hello sir.. A small doubt Can you tell me what if Geostrophic wind's path if coriolis parameter was going towards right in the NH?
Professor!! Indeed, the way you explained this complex topic so easily, there's no one that deserves the " Favorite topic" tag more perfectly than you ☺️☺️
I don't think my scientific calculator is broken, but every time I plug in the values for the f parameter, I get a different value compared to yours. My f value is -0.0001233789. Did I miss a step?
Very Informative yet simple explanation, Thank You
I'm going to do my boring man but I just wanted to say that this is the differential operator nabla and not the gradient, just to avoid people from possible confusion :')
Thanks
Thank you.......... :)
very helpful, thanks!
Excellent.
Hi mam Please help me how can I contact you??
This is great!
That was nice.
This was cool.
thank you so much!!
Great video! Thanks
What about the curvature term? When we see that the Coriolis term can be equal to the pressure gradient, when R0<<1
thanks for the video
Great explanation!
At q#1 isnt dv/dt included im the total acceleration?
A question if you don't mind. I don't really understand what it means to stand at Buffalo and have a planetary vorticity given by the local vertical component of 2 x Omega. How am I to picture the planetary vorticity at Buffalo: in what sense is there spin about the local vertical at Buffalo and what does it's magnitude being smaller than 2 x Omega physically mean? Or is it the curl of the local velocity shear of the earths surface at Buffalo that is the planetary vorticity there?
Thank you for the video, could you please help me with a question professor. For internal tides, in vertical mode decomposition, why is mode zero barotropic and mode 1 2 3 and so on baroclinic. Also, can the barotropic and baroclinic mode be in the same fluid at the saem time, how can we picture this? I mean if the ocean stratified? Thank you very much
could you please answer one of my questions? I don't understand why the density of A and B are the same in the barotropic flow(06:44), isn't A and B in the different isopycnic lines?
Very well explained, thank you!
Legendary lecture thanks a lot
Hello! Thank you very much for your video, it is very clear! Still I have two questions that I hope you can answer me Why is the boundary condition of the model only one? It is also mentioned that there is no flow through the eastern edge, how could this be explained? Greetings from Patagonia Argentina!
from india ...good lecture
